Canada is a major global mining jurisdiction and a leading producer of minerals such as potash, uranium, gold, nickel, iron ore, copper, zinc, aluminum and diamonds. The mining sector contributes significantly to Canada’s exports and supports economic activity across the country.

Canada is a federation, and the legal framework for mining is a mix of Federal and provincial law. Under Canada’s Constitution Act, 1867, provinces primarily own and regulate mineral resources, including exploration and mining on provincial Crown lands, while the Federal government has jurisdiction over certain related matters, including mining on Federal lands, foreign investment, interprovincial and international trade and aspects of environmental regulation. Each province and territory has its own mining legislation governing mineral tenure, royalties and environmental and safety requirements.

Regulatory authorities vary by jurisdiction. Typically, provincial ministries administer mineral tenure and mining operations, while provincial environmental and occupational health and safety regulators oversee those aspects of mining. At the Federal level, Natural Resources Canada develops mining and mineral policy. Certain commodities are subject to specific Federal oversight, including uranium, which is regulated as a strategic nuclear material and requires Federal licensing by the Canadian Nuclear Safety Commission under the Nuclear Safety and Control Act (Canada).

Canada’s legal system is based predominantly on the common law in nine provinces and three territories, with the civil law system applying in Québec.

Canada is a party to the Convention on the Recognition and Enforcement of Foreign Arbitral Awards (New York Convention), which has been in force in Canada since 1986 and is implemented through the Federal United Nations Foreign Arbitral Awards Convention Act (Canada), together with corresponding provincial legislation. As a result, foreign arbitral awards are generally enforceable in Canadian courts, subject to limited statutory defences. Canada is also a signatory to other international investment treaties and trade agreements that provide protections to foreign investments, including mining investments.

Canada launched a comprehensive Critical Minerals Strategy in 2022 to secure the supply of minerals considered essential to clean technologies, economic resilience and national security. The Strategy, led by Natural Resources Canada, sets out a whole‑of‑government framework covering the full value chain from exploration to reclamation.

The Federal government has identified a list of critical minerals comprising 34 minerals and metals, including lithium, cobalt, graphite, nickel, rare earth elements, uranium and potash. The Strategy is supported by approximately C$3.8 billion in Federal funding announced in Budget 2022 to advance critical mineral exploration, processing capacity, infrastructure and domestic and allied supply‑chain development.

Key objectives of the Strategy include accelerating responsible project development, improving coordination and efficiency in permitting and regulatory processes, attracting domestic and foreign investment in critical mineral projects and ensuring high standards of environmental protection, Indigenous participation and social responsibility.

In parallel, a number of provinces and territories have adopted their own critical minerals strategies and policy initiatives, and several jurisdictions have undertaken regulatory and administrative reforms aimed at facilitating the development of critical mineral projects while maintaining environmental and consultation requirements.

Overall, Canadian government policy strongly promotes critical minerals development through targeted funding, tax credit and infrastructure programs, alongside a heightened and rigorous foreign investment review regime under the Investment Canada Act for transactions involving strategically sensitive critical mineral assets.

Canada supports mining through a combination of tax incentives and targeted funding programs.

A key support is a flow-through share arrangement, by which exploration companies can issue flow-through shares which allow them to “flow” Canadian exploration and development expenses to investors, enabling investors to deduct those amounts in computing taxable income and, for eligible expenses, claim an additional tax credit.

Federally, the Mineral Exploration Tax Credit (METC) provides a 15% non‑refundable credit for eligible exploration expenses renounced to flow‑through share investors and the Federal government has proposed extending the METC to March 31, 2027.

Canada also introduced the Critical Mineral Exploration Tax Credit (CMETC) in Budget 2022, a 30% non‑refundable credit for specified critical mineral exploration expenses incurred in Canada and renounced to flow‑through share investors, available for qualifying agreements through March 31, 2027.

Provinces may offer complementary incentives. For example, in Saskatchewan, the Saskatchewan Mineral Exploration Tax Credit (SMETC) provides a 30% provincial credit, and the combined Federal/provincial incentives may result in an overall credit of 45% to 60% depending on the applicable Federal credit.

Beyond tax measures, Federal programs support critical minerals projects and value chains through infrastructure and research and development funding, including the Critical Minerals Infrastructure Fund (CMIF) and the First and Last Mile Fund (FLMF). Additionally, the Government of Canada’s Budget 2025 materials and related announcements describe a proposed C$2-billion Critical Minerals Sovereign Fund to make strategic investments (including equity, loan guarantees and offtake agreements) in critical mineral value chains.

In addition to tax incentives and grants, Federal Crown corporations such as the Business Development Bank of Canada (BDC) and Export Development Canada (EDC) provide financing and risk‑management solutions that can support mining companies and critical minerals value chains, including in connection with international transactions.

With the limited exception of the production of uranium (see more below), Canada does not have any blanket restrictions on foreign investment in the metals and mining sector. The Federal Investment Canada Act (ICA), however, is a statute of general application governing investments in Canadian assets or businesses by non-Canadian investors.

The ICA contains two notification and review regimes: (i) The “net-benefit to Canada” regime, which applies to an acquisition of control of a Canadian business; and (ii) a national security review regime, which applies to all investments by non-Canadian investors in Canadian companies or assets.

Net-benefit to Canada regime

An acquisition of control of a Canadian business by a non-Canadian investor is either notifiable or reviewable under the ICA.

The financial threshold for a net‑benefit review varies depending on the country of ultimate control of the investor. For private investors from “trade agreement” countries (i.e. ultimate control resides in a country with which Canada has a trade agreement, like the USA, Mexico or European Union member states), the review threshold is relatively high (approximately C$2.179 billion in enterprise value for 2026, indexed annually). Lower thresholds apply to World Trade Organization investors. State‑owned enterprise (SOE) investors and non-WTO investors are subject to even lower financial thresholds for review, both based on the book value of the Canadian business’s assets.

Where a net‑benefit review is required, the government considers factors such as economic impacts, employment, productivity, technological development, competition and compatibility with national policies. The review process is often political; nevertheless, most reviewable investments under the net benefit to Canada regime are allowed to proceed with commitments or undertakings from the investor to satisfy the “net benefit to Canada” test.

In 2022, the Canadian government issued a policy statement that acquisitions of control of Canadian businesses involving critical minerals by foreign SOEs or investors closely tied to foreign governments would be approved under the net‑benefit test only on an exceptional basis. This policy remains in place but is not binding on the new Canadian government.

Where an acquisition of a Canadian business by a non-Canadian falls below the relevant thresholds and is not reviewable, it is merely notifiable and the investor must provide a notice at any time prior to the closing of the investment or within 30 days thereafter.

National security review regime

The ICA also contains a national security review mechanism (akin to CFIUS in the United States) that allows the Canadian government to review, prohibit or impose conditions on a broad range of direct and indirect investments by non-Canadians on the basis of national security concerns. Any investment, regardless of the size of the target Canadian business or of the investment, can be reviewed to determine if it could be “injurious to national security.”

SOE investments in the Canadian critical minerals mining sector receive heightened scrutiny under the national security review regime.

Significantly, the Canadian government has adopted, but not yet implemented, new legislation that would require the pre-closing notification of foreign investments in certain prescribed sectors. The prescribed sectors have not yet been identified, but critical minerals are likely to be included in the new regulation.

Uranium policy

A distinct foreign ownership policy applies to uranium mining. Under the Federal Non‑Resident Ownership Policy in the Uranium Mining Sector (NROP), non‑Canadian ownership of a uranium‑producing mine is generally limited to 49% once, or if, the project achieves its first commercial production. There are exemptions where the project is Canadian‑controlled in fact or no suitable Canadian partners are available.

Canada generally imposes no restrictions on the repatriation of capital, profits interest or dividends by foreign mining investors. The Canadian dollar is freely floating and fully convertible, and Canada maintains no general foreign exchange or capital controls. As a result, dividends, interest, return of capital, debt repayments and sale proceeds may be remitted abroad freely through normal banking systems.

The principal constraints on outbound payments arise from taxation and financial reporting rules. Payments to non‑residents may be subject to withholding tax under Part XIII of the Income Tax Act (Canada), with a default rate of 25% that is commonly reduced under Canada’s tax treaties.

In addition, Canadian financial institutions must report large international electronic funds transfers to Financial Transactions and Reports Analysis Centre of Canada (FINTRAC) under Canada’s Proceeds of Crime (Money Laundering) and Terrorist Financing Act. Apart from routine tax compliance and anti-money-laundering reporting, Canada imposes no special limits on the repatriation of earnings or capital by foreign investors.

Canada does not impose general export quotas or bans on mineral commodities. Mining companies are generally free to export mineral products. There is no national requirement that raw minerals be beneficiated or processed domestically prior to export.

Limited exceptions exist at the provincial or sector‑specific level. For example, Ontario’s Mining Act provides that mining rights are subject to a condition requiring that ores or minerals be treated and refined in Canada, failing which the Crown may declare the tenure void. Newfoundland and Labrador and Nova Scotia have pursued similar local‑processing policy objectives, albeit through different, project‑specific legal mechanisms.

Certain commodities are subject to Federal export licensing. In particular, exports of uranium and other nuclear substances, equipment or related technology require licensing by the Canadian Nuclear Safety Commission under the Nuclear Safety and Control Act and associated regulations, reflecting Canada’s nuclear non‑proliferation obligations.

Exports of rough diamonds from Canada require a Kimberley Process Certificate issued under the Export and Import of Rough Diamonds Act (Canada), which implements Canada’s international commitments to prevent international movement of conflict or “blood” diamonds.

Canada generally does not impose export tariffs on minerals or metals. Canada’s tariff legislation is focused on imports rather than exports, and Canada’s trade policy generally discourages export duties or quantitative export restrictions.

Imports may be subject to customs duties under the Customs Tariff and applicable trade agreements, and Canada has trade remedy mechanisms for specific products, including anti‑dumping and countervailing duties under the Special Import Measures Act (Canada).

Imported mining equipment is subject to Canada’s standard 5% Goods and Services Tax (GST) at the time of importation, but GST is a broadly applicable consumption tax rather than a tariff and is generally recoverable by registered businesses by way of input tax credits.

From time to time, Canada and its trading partners have imposed or responded to retaliatory tariffs on certain metal products, such as steel and aluminum, in the context of broader trade disputes (for example, U.S. Section 232 measures and Canada’s counter‑measures). These actions reflect temporary trade policy responses and are not persistent features of Canada’s mining law or tariff regime.

Canadian mining law does not require any government entity or local partner to hold an equity interest in mining projects. Mining claims and leases may be held entirely by private companies, whether domestic or foreign, and there is no requirement for state equity participation, free‑carried interests or compulsory joint ventures.

Although governments typically own Crown mineral rights and receive royalties and rents, these are non‑equity fiscal instruments and do not confer ownership, control or profit participation. Governments act as resource owners and regulators, not project partners, unless they choose to participate voluntarily.

Similarly, there is no general legal requirement to transfer equity to Indigenous governments. Equity participation and profit‑sharing arise through negotiated impact benefit agreements rather than statutory ownership requirements.

In Canada, minerals are generally owned by the Crown, except where historic freehold mineral title exists. Mining companies do not acquire fee simple ownership of land but instead hold statutory mineral tenure, typically a mineral claim or mining lease, authorizing exploration and, where applicable, extraction.

Under the Constitution Act, 1867, provinces own most mineral rights and have primary jurisdiction over the exploration, development and management of non‑renewable natural resources, while the Federal government retains jurisdiction over matters such as Federal lands, foreign investment review, nuclear regulation, interprovincial and international trade and certain environmental matters. Accordingly, provincial Crowns issue most mining tenure under provincial legislation, though in limited areas mineral rights must be acquired from private owners.

A mineral claim is generally a transferable statutory exploration right but will typically have limited project‑finance utility relative to leases, with security regimes varying by province. Transfers are usually effected by registry registration, with approval requirements varying by province. By contrast, a mining lease is generally considered an interest in land that may be mortgaged or charged as security, subject to statutory conditions, registration and often ministerial approval. Title to minerals remains with the Crown (or freehold owner) until lawful extraction.

In Canada, mineral rights are often legally distinct from surface land rights. Ownership of a mineral claim or lease does not, by itself, confer ownership of or an unconditional right to use the surface land. Where minerals are Crown‑owned or otherwise severed from surface title, a mining operator must obtain lawful surface access in addition to mineral tenure.

If the surface is Crown land, surface access is typically obtained through a government‑issued surface lease, licence or permit. Where the surface is privately owned, the mining company generally negotiates a surface access agreement with the landowner, including compensation for disturbance, loss of use and damages. Across Canada, mining statutes provide mechanisms to ensure reasonable access. Surface owners may not unreasonably refuse access where minerals are severed but are entitled to fair compensation. If an agreement cannot be reached, either party may apply to a statutory tribunal, arbitrator or court to determine access terms and compensation.

Surface owners retain ownership and may continue compatible land uses, while mining operators must minimize disturbance, ensure safety and rehabilitate the land in accordance with environmental and closure requirements. Overall, the legal framework balances subsurface extraction rights with surface ownership through compensation and regulated access.

Prospectors and exploration companies in Canada typically obtain exploration rights over Crown‑owned minerals by registering a mineral claim or by obtaining an exploration licence or permit under provincial or territorial mining legislation. These tenure systems are often described as “free entry” (or modified free entry) in the sense that eligible applicants may acquire mineral tenure over available Crown lands by applying/recording the right in the prescribed manner, rather than through a negotiated Crown contract.

Historically, claims were acquired by physically staking posts on the ground and then recording the claim with the mining recorder, but many Canadian jurisdictions now administer claim acquisition through electronic, map‑based registry systems. Under these systems, the applicant selects available parcels/cells on a digital map and registers the claim electronically, with the registry serving as the authoritative public record of mineral title and changes. Claim registration is generally inexpensive and processed quickly, often instantaneously or within days where electronic systems are used, with government fees typically limited to modest per‑cell or per‑hectare charges.

Within the bounds of exploration tenure, claimholders can typically carry out early‑stage activities such as prospecting, sampling, surveys and drilling. However, activities that disturb land or the environment often trigger separate approvals under the jurisdiction’s exploration/land‑disturbance framework (for example, plans/permits for certain early exploration activities or an authorization for “impact‑causing” work).

Exploration claims are typically issued with an initial term of one or several years, varying by jurisdiction, and are maintained under a “use it or lose it” system. To keep a claim in good standing, the holder must perform prescribed exploration/assessment work (or make payments in lieu where permitted) and submit the required reports through the registry/reporting process. Failure to maintain the claim typically results in forfeiture of the mining tenure.

If a project advances toward development, the exploration claim must generally be converted into a mining lease or similar production‑stage tenure to support commercial or production‑level extraction. Conversion requirements vary, but commonly include application fees/rents and, in some jurisdictions, survey and public notice steps tied to the lease issuance process.

Relative to exploration claims, leases are typically treated as the longer‑term production tenure. However, a mining lease secures mineral rights only and does not, by itself, authorize mining operations. Commercial mining may proceed only after obtaining the separate environmental, operational, and mine permits required under applicable legislation, and the sequencing of lease issuance and permitting varies by jurisdiction.

Once an exploration property advances toward commercial mine development, the proponent will generally need to secure a mineral lease or equivalent production‑stage tenure from the Crown over the relevant mineral lands. A lease is typically the tenure used to support commercial extraction and project finance, whereas a claim is primarily an exploration right. As a general framework, once exploration has identified mineral reserves warranting mine construction, the proponent must obtain a mining lease along with environmental and other permits.

A mining lease is a statutory property interest issued under provincial/territorial mining legislation that grants the lessee the right (subject to its terms) to extract minerals from the leased area and sell them once extracted. It does not convey fee simple title to land and is not, by itself, a “permit to mine.” In other words, the lease secures mineral rights, while mine construction and operation are controlled through separate regulatory approvals.

The requirements to obtain a lease vary by jurisdiction but commonly include: (a) holding valid underlying mineral tenure over the lands (often a claim), (b) satisfying prescribed work/technical requirements, (c) providing a survey plan or legally sufficient description of the lease lands and (d) paying applicable application fees and/or rent. Some jurisdictions link lease issuance to broader project readiness (e.g. approval of rehabilitation and restoration plans, issuance of environmental authorizations and formal survey plans).

Lease term and renewal are also jurisdiction‑specific. Terms commonly run for multi‑decade periods with renewal opportunities, varying by jurisdiction.

As previously mentioned, holding a lease does not eliminate permitting obligations. Commercial mining generally proceeds only after obtaining the separate environmental, operational and mine permits required under applicable legislation.

First, projects may require an environmental assessment under Federal and/or provincial/territorial regimes, and regulators increasingly coordinate to avoid duplication. Second, proponents typically require a mine construction/operations approval (often issued under a mines or environmental protection statute or regulation) covering the mine plan, environmental protection measures and operating conditions.

Closure and reclamation obligations are central and are often integrated into the front end of approvals. Across Canada, a mine closure plan (or equivalent) is commonly required before mine production can proceed and the proponent must typically provide financial assurance to secure estimated closure costs. Closure planning is site‑specific and typically includes progressive reclamation, cost estimates, temporary closure planning and post‑closure monitoring concepts.

In limited circumstances, mineral interests may be privately held rather than Crown‑owned. In those cases, the proponent typically acquires the economic mineral rights by private agreement, but the construction, operation and closure of a mine remain governed by the same statutory permitting, environmental assessment and reclamation regimes that apply to mining on Crown mineral lands.

Mining operations conducted on Crown‑owned mineral lands are generally subject to statutory royalties or production‑based payments payable to the Crown under applicable mining legislation and/or the terms of the relevant mineral lease. These payments compensate the Crown for the extraction of non‑renewable public resources and operate separately from general income taxation. Royalty structures vary by jurisdiction and, in some cases, by commodity, but commonly take the form of profit‑based, net‑value‑based or hybrid regimes, with some provinces applying gross revenue or volume‑based royalties for specific minerals.

Royalty obligations are typically established by statute and incorporated by reference into Crown mineral dispositions. In addition to royalties, tenure holders are commonly required to pay annual land rents or licence fees, which are typically nominal and designed to maintain mineral rights rather than capture resource value. Failure to comply with royalty or tenure‑related payment obligations may give rise to statutory enforcement measures, including interest and penalties, recovery against production or proceeds, and, in serious cases, suspension or cancellation of mineral tenure. In summary, production from Crown mineral lands is subject to a jurisdiction‑specific royalty framework grounded in public ownership of mineral resources and enforced through the mineral tenure system.

Mineral claims and mining leases are generally transferable, but the degree of government oversight typically increases as tenure advances from exploration to production. Early‑stage exploration titles (such as unpatented claims) are often more freely transferable, subject to registration requirements, whereas mining leases or other production‑stage tenures commonly require ministerial consent to an assignment to ensure continued regulatory compliance and public‑interest oversight. Once approved, the transferee generally assumes all obligations attached to the tenure.

There is also an important distinction between claims and leases from a financing perspective. While exploration claims are usually transferable statutory interests and are generally viewed as having limited standalone collateral value, mining leases are more commonly treated as durable property interests capable of supporting project financing. As a result, security is more readily taken over mining leases than over exploration claims, whether through property-based charges or functional equivalents under secured transactions regimes. The creation, registration and enforcement of security interests is typically subject to statutory conditions and, in many cases, government consent. In practice, assignments and encumbrances of mineral tenure are permitted but are subject to oversight to protect the public interest and maintain accurate tenure records.

Indigenous peoples in Canada (First Nations, Métis and Inuit) hold constitutionally protected rights highly relevant to mineral exploration and mining. Section 35 of the Constitution Act, 1982 recognizes and affirms existing Aboriginal and Treaty rights. While there are no Indigenous ownership or participation quotas in mining, projects operate within a constitutional framework requiring meaningful engagement with Indigenous communities where their rights may be affected.

Under Supreme Court of Canada jurisprudence, the Crown (Federal or Provincial, as applicable) has a legal duty to consult and where appropriate accommodate Indigenous groups when it contemplates conduct – such as granting approvals, licences or permits – that may adversely affect Aboriginal or Treaty rights, including Aboriginal title (Haida Nation v. British Columbia, 2004 SCC 73; Mikisew Cree First Nation v. Canada, 2005 SCC 69). The depth of consultation depends on the strength of the asserted rights and potential impacts. When the strength of the claim is strong and the impacts are high, then consent of the Indigenous group may be required. Modern treaties may also impact the content and scope of the duty to consult, with some treaties establishing co-management regimes. Although consultation is often carried out procedurally by proponents or fulfilled by regulatory processes, the legal duty remains with the Crown.

Canada has adopted legislation to implement the United Nations Declaration on the Rights of Indigenous Peoples (UNDRIP) at the Federal level. One province and one territory have also passed legislation implementing UNDRIP in their jurisdictions. Free, Prior and Informed Consent (FPIC) has not been interpreted as an automatic veto under Canadian law. However, the interaction between FPIC and the constitutional duty to consult has not yet been finally determined in Canadian law.

Mining in Canada is subject to extensive environmental regulation at both the Federal and provincial levels. Proposed mining projects may trigger environmental assessment requirements before approvals can be granted. At the Federal level, certain large mining projects are designated under the Impact Assessment Act (Canada) and require a Federal impact assessment where they exceed prescribed thresholds or engage areas of Federal jurisdiction, such as impacts on fish habitat, Indigenous rights or Federal lands.

In addition, each province and territory has its own environmental assessment legislation applicable to mining projects (e.g. British Columbia’s Environmental Assessment Act and Saskatchewan’s Environmental Assessment Act). For major projects, Federal and Provincial authorities often coordinate their review processes to avoid duplication. Environmental assessments typically involve baseline environmental studies, evaluation of potential impacts on water, wildlife, air quality, communities and Indigenous rights, extensive public and Indigenous consultation and the imposition of mitigation measures and conditions as part of the final approval decision. Completion of the assessment is generally a prerequisite to key project permits.

Following environmental assessment approval, mining projects require numerous regulatory permits, including mine construction and operating permits, water use licences, air emissions approvals and tailings management authorizations. Mining activities must also comply with Canada’s Fisheries Act, which prohibits the deposit of deleterious substances into waters frequented by fish unless expressly authorized by regulation.

Mine closure and reclamation are core regulatory requirements for mining operations in Canada. Provincial and territorial mining legislation generally requires proponents to plan for closure early in the project lifecycle and to submit a mine closure or reclamation plan for regulatory approval. These plans typically address the rehabilitation of disturbed lands, long‑term stability of waste rock and tailings facilities, removal or decommissioning of infrastructure, management of contamination and site revegetation or approved end land uses.

A critical feature of these regimes is the requirement to provide financial security, such as a bond or letter of credit, sufficient to cover the estimated cost of closure and reclamation. This security is intended to protect the Crown from assuming remediation liabilities if a mine is abandoned or the operator becomes insolvent and is generally released only once closure objectives have been achieved.

Environmental compliance is subject to ongoing regulatory oversight. Inspectors may conduct audits and site inspections and issue compliance or remediation orders. Serious non‑compliance can result in substantial monetary penalties, prosecution under Federal or provincial environmental laws, personal liability for directors and officers in appropriate cases and suspension or revocation of permits. Mines are also subject to ongoing monitoring and reporting obligations, with climate‑related considerations increasingly forming part of regulatory approvals for major projects.

Mining health and safety in Canada is primarily regulated at the provincial and territorial level through occupational health and safety legislation. These regimes impose detailed requirements addressing core mining hazards, including ground control, ventilation, explosives, equipment safety, emergency preparedness, worker training and incident reporting and are enforced through regular inspections by provincial mine safety regulators. In many jurisdictions, mandatory mine rescue and certification programs also apply.

Certain mining activities are subject to additional Federal oversight. In particular, uranium mines and mills are regulated by the Canadian Nuclear Safety Commission under the Nuclear Safety and Control Act (Canada), which imposes specialized requirements addressing radiation protection, occupational exposure limits and nuclear safety, in addition to applicable provincial health and safety rules. Serious safety breaches may result in significant penalties, including prosecution of corporations and, in appropriate cases, individuals, under occupational health and safety laws.

Climate‑related disclosure is an area of increasing focus for the Canadian mining sector. While there is currently no mining‑specific climate disclosure statute, Canadian reporting issuers remain subject to general securities law requirements to disclose material risks, which may include climate-related risks. The Canadian Securities Administrators (CSA) previously proposed National Instrument 51‑107 (climate-related disclosure), but as of April 2025, the CSA has paused further work on a new mandatory climate disclosure rule. Separately, the Canadian Sustainability Standards Board (CSSB) has issued Canadian Sustainability Disclosure Standards (CSDS 1 and CSDS 2) effective for annual periods beginning on or after January 1, 2025, which are voluntary but could potentially influence future regulation. At the project level, major mining developments subject to Federal impact assessment must assess greenhouse gas emissions and climate impacts and many operating mines are already required to quantify and report emissions under Federal or provincial carbon pricing regimes.

Canada does not currently impose sector‑specific decarbonization obligations on market participants across the mining value chain (such as compulsory emissions reductions, technology mandates, or renewable energy requirements). Instead, decarbonization obligations arise indirectly through economy‑wide climate legislation. At the Federal level, Canada has legislated national greenhouse gas reduction targets – net‑zero emissions by 2050 and a 40–45% reduction below 2005 levels by 2030 – under the Canadian Net‑Zero Emissions Accountability Act, but these targets are binding on the Federal government rather than on individual mining companies or sectors.

For mining companies, the primary binding decarbonization obligation arises through carbon pricing. Most mining operations are subject to the Federal Greenhouse Gas Pollution Pricing Act or equivalent provincial regimes, which apply output‑ or intensity‑based pricing systems to large industrial emitters and impose financial costs on emissions above applicable benchmarks, without prescribing how reductions must be achieved.

Mining-sector climate obligations are primarily shaped by economy‑wide frameworks (carbon pricing and fuel standards) rather than a mining‑specific emissions statute. Current and pending reforms focus instead on strengthening carbon pricing design, expanding climate‑related disclosure and implementing fuel‑standard regulations, reinforcing a predominantly market‑based and technology‑neutral approach to decarbonization.

In addition to climate‑related disclosure and economy‑wide decarbonization targets, Canada’s climate framework includes several laws and regulations that may affect market participants across the mining value chain. The most significant is carbon pricing. Under the Greenhouse Gas Pollution Pricing Act (Canada), greenhouse gas emissions are priced through a Federal fuel charge and an Output‑Based Pricing System (OBPS) for large industrial emitters. Mining operations are typically subject to the OBPS or equivalent provincial systems that apply carbon costs to emissions above sector‑specific intensity benchmarks, rather than mandating specific technologies or reductions.

Other climate‑related measures indirectly affect mining. Federal Clean Fuel Regulations require gasoline and diesel suppliers to progressively reduce the carbon intensity of fuels, influencing fuel costs for energy‑intensive operations.

Alongside these obligations, the Federal government offers incentives, including refundable clean‑technology investment tax credits, to support industrial decarbonization.

No further comment.

A significant recent development in Canada is the increased policy emphasis on accelerating mine development, particularly for critical minerals, while maintaining existing environmental and Indigenous consultation requirements. Both Federal and provincial governments have acknowledged that lengthy permitting and approval timelines can deter investment and have introduced initiatives aimed at improving regulatory efficiency and reducing duplication.

At the Federal level, the Building Canada Act establishes a framework to identify and advance major projects deemed to be in the national interest, including certain mining and critical minerals projects, with the stated objective of streamlining Federal review and approval processes and improving regulatory certainty. In parallel, the Federal government has committed to enhanced coordination with provinces under the Impact Assessment Act to avoid duplicative assessments for major resource projects.

At the provincial level, Ontario enacted the Building More Mines Act, 2023, which amended the Mining Act with the objective of modernizing and streamlining aspects of the mine development and closure planning process, as part of Ontario’s broader critical minerals strategy.

Canada has also increased its engagement in international cooperation on critical minerals, reflecting the strategic importance of secure mineral supply chains for clean technology and advanced manufacturing. Overall, the regulatory environment continues to evolve in response to growing demand for minerals, geopolitical considerations and competitiveness concerns, making ongoing monitoring of legal and policy developments important for mining proponents and investors.
