OTTAWA — Canada has transformed from a predictable USMCA partner into one of the more aggressive users of trade defense instruments in North America, layering retaliatory surtaxes on American goods while simultaneously erecting new barriers against imports produced with forced labor. For exporters selling into Canada, the regulatory environment now demands origin verification at a granular level and an understanding of a remission system that has become as consequential as the tariffs themselves.
The counter-tariff regime, implemented through two orders-in-council effective September 8, 2026, imposes surtaxes of 15%, 25%, or 50% on approximately C$27.6 billion in annual imports of U.S.-origin goods . The rates are tiered by product category: air conditioning machinery, forklifts, and harvesting equipment face 15%; dairy products, sawn wood, toilet paper, carpets, kitchen appliances, rail locomotives, and trailers face 25%; and certain dairy products and steel and aluminum products face 50% . The steel and aluminum surtax rate doubled from 25% to 50% under the amended order .
Crucially, the surtax applies based on origin, not shipment routing. Goods that originate in the United States are subject to the surtax even if they are exported from a third country into Canada, and the origin determination follows the CUSMA marking rules rather than the exporter’s declaration . This closes the obvious workaround of routing U.S.-made goods through Mexico or Europe before shipping to Canada.
The remission system, however, has blunted the practical impact for many importers. Canada assessed C$14.1 billion in counter-tariffs from March 2025 through October 2026, but C$8.9 billion was remitted or relieved, leaving net revenue of only C$5.2 billion . Finance Minister François-Philippe Champagne announced in November 2026 that remission would be extended for “non-steel goods” made in the U.S. and used in Canadian mining, quarrying, and oil and gas extraction, as well as for products used by public health, education, safety, and national security organizations, through June 30, 2028 .
Simultaneously, Canada is narrowing remission to incentivize domestic sourcing. Tariff relief will end for certain U.S.-made trailers as of December 1, 2026, and for aluminum wire, pipes, tubes, and some paperboard products from February 1, 2027 . The Department of Finance framed the changes as “to incentivize the use of domestic inputs,” signaling that the remission system is being calibrated to support Canadian manufacturers rather than simply offsetting tariff costs for importers .
The forced-labor import prohibition represents a separate and potentially broader barrier. A bill introduced in 2026 would prohibit the importation of goods produced wholly or in part by forced labor, defined according to the International Labour Organization’s Forced Labour Convention . The Minister of Foreign Affairs would be authorized to establish a list of goods for which there are reasonable grounds to suspect forced labor, and importers of listed goods would be required to provide information to the Canada Border Services Agency on request, failing which the goods would be deemed prohibited . Customs officers would have authority to detain goods for up to 90 days to make a determination .
For foreign exporters, the forced-labor bill creates a due-diligence obligation that extends beyond documentation into supply chain traceability. The bill does not specify which countries or sectors will be targeted, but the listing mechanism gives the government flexibility to respond to diplomatic and public pressure. Exporters with complex supply chains, particularly in sectors like apparel, electronics, and agriculture, should prepare to demonstrate that their production processes are free of forced labor if their goods are listed.
The economic context for these measures is Canada’s extraordinary dependence on the U.S. market: approximately 70% of Canadian exports go to the United States, and nearly 60% of Canadian imports come from there . The counter-tariffs are a response to U.S. duties imposed on Canadian goods, and the remission system reflects the reality that many Canadian businesses cannot easily replace U.S. inputs. The government has allocated C$7.5 billion to support affected sectors, including a mechanism to diversify export markets .
For exporters to Canada, the operative requirements are now: accurate origin determination under CUSMA marking rules for any goods with U.S. content; awareness of the remission categories and the narrowing eligibility timeline; and supply chain due diligence for forced labor risk. The Canadian market remains open, but the compliance infrastructure required to access it has thickened considerably in the past eighteen months.
