Canada’s escalating trade confrontation with the United States is reshaping grocery purchasing and supply chains, as consumers avoid U.S. goods while retailers expand domestic sourcing, diversify imports and make country-of-origin information more visible. Vince’s Market president Giancarlo Trimarchi said his four Greater Toronto Area stores now source about 90% of their produce from Canada, including Quebec strawberries instead of U.S. supplies. The shift comes after trade talks collapsed on Aug. 21 and President Donald Trump imposed 50% tariffs on $20 billion of Canadian products, followed by additional import restrictions and Canadian retaliation. The dispute is occurring despite the United States-Mexico-Canada Agreement, under which most U.S. exports enter Canada duty-free, and the two countries’ extensive economic ties. Canada’s vegetable-import share from the United States fell to 62.6% in July from 69% in July 2023, while more than half of fruit imports still came from the United States. Canada is investing about C$3 billion over a decade in greenhouses, but harsh winters, higher costs and provincial regulations remain obstacles to greater food self-reliance.
