The recent escalation of Canada-US tariffs is materially reshaping supply chains and business relationships. Canadian companies—and multinational enterprises with Canadian supply chains—now face heightened legal and operational uncertainty, prompting a reassessment of cost structures, supply‑chain models, and customs‑compliance strategies.

In this bulletin, we provide an overview of Canada's current retaliatory tariff regime, including Canada's retaliatory tariff lists of March 4th, March 13th, and April 9th, as well as what companies can do to mitigate the impact of duties. We further explore the announced remission opportunities for those businesses importing US-origin goods. Lastly, we outline Canadian provinces' efforts to reduce inter-provincial barriers to trade.1

Canada's proposed Productivity Mega Deduction would allow businesses to immediately write off the full cost of newly acquired capital assets, including aircraft and flight simulators, rather than spreading deductions over multiple years.
