A Canadian court awarded $800,000 in damages to a couple defamed by serious false allegations of sexual assault and criminal misconduct spread through social media.

Ontario's Rules of Civil Procedure now include strict amendments requiring lawyers and expert witnesses to certify the authenticity of every citation and authority used in court materials. These new anti-hallucination provisions impose significant penalties for presenting AI-generated fabricated authorities, fundamentally shifting accountability for artificial intelligence use in litigation.

The Alberta Court of King's Bench has confirmed its jurisdiction to grant injunctive relief against the Alberta Energy Regulator despite a broadly worded statutory privative clause. This landmark decision, arising from Sumerian Oil & Gas's application to stay a suspension order affecting approximately 900 wells, represents one of the first considerations of the Supreme Court of Canada's recent Democracy Watch ruling and may significantly impact future disputes involving AER orders.

The British Columbia Court of Appeal has left open the possibility that pharmaceutical manufacturers may owe a duty of care to develop safer alternatives to their existing products, even when those products are properly approved and labeled.

I.F. contrasts sharply with a recent California Supreme Court ruling that rejected such a "duty to innovate," potentially setting Canada on a divergent path in product liability law.

Effective September 8, 2026, Canada implemented retaliatory tariffs on certain U.S. goods in response to the initial 50% tariffs imposed by the US under Section 338 of the Tariff Act of 1930. To operationalize these measures, the Canada Border Services Agency (CBSA) issued Customs Notice 26-23, establishing binding administrative rules on how the surtax will be applied, calculated, and collected.

With Labour Day now behind us, Parliament Hill is gearing up for its September 21 return. Canada’s counter-tariffs on nearly $28 billion in American goods are now in force, and the United States has already escalated in response: President Trump has signed measures to ban certain Canadian alcohol, dairy-related products, molasses, non-alcoholic beer, motorcycles and mopeds from entering the U.S. market as of September 29, while modifying the list of Canadian goods subject to 50% tariffs effective September 15 and directing action to remove Canadian-origin products from U.S. government procurement schedules.

Under Order in Council 1358-2026, the Québec government authorizes, from September 7, 2026 to January 31, 2027, the Centre d'acquisitions gouvernementales (the “CAG”) to depart from the general principle that public calls for tenders must be open and without discrimination to foreign suppliers from jurisdictions bound by an intergovernmental agreement with Québec.

A regulatory shift now under consideration in Ontario could reshape how the province’s medical aesthetic clinics operate. The proposal, which would change how nurses are authorized to administer medical aesthetic services, invites a broader look at how Ontario currently regulates cosmetic injections and how the proposed changes would align the province more closely with the regulatory frameworks already in place elsewhere in Canada. While these procedures are often marketed as routine “spa” services, they remain medical acts that involve prescription products and carry clinical risks.

On July 29, 2026, Health Canada announced that it had obtained a permanent injunction against a Québec-based company in connection with the sale of unauthorized injectable peptides in Canada.

Unmanned Aerial Systems (UAS), commonly referred to as drones, are increasingly used in Canada for commercial purposes such as infrastructure inspection, real estate photography, agriculture, filmmaking, mapping and resource exploration. Their advantages are clear: they are flexible, relatively inexpensive and capable of collecting information from angles and locations that would otherwise be difficult to access.

The new framework effectively positions public drug and supplemental benefits plans as payers of last resort. Where a member is entitled to alternative coverage, that coverage must be accessed first, and the public plan will only pay in limited circumstances and only up to the unpaid portion of the claim.
