Fifty Percent US Tariffs Set to Hit Canadian Exporters August 19, Deepening Manufacturing Job Losses

Canadian manufacturers are bracing for a fresh blow as new fifty percent US tariffs on a wide range of Canadian goods are set to take effect on August 19, deepening a job crisis that has already cost the country tens of thousands of manufacturing positions.
President Donald Trump signed the measures on July 20 through a series of presidential proclamations invoking Section 338 of the US Tariff Act of 1930, a provision that allows the president to impose duties on countries found to discriminate against American commerce. The proclamations cite Canadian provincial restrictions on US alcohol sales along with broader trade grievances in the dairy and automotive sectors. According to the Office of the US Trade Representative, the new duties affect close to twenty billion dollars in annual Canadian exports, and unlike earlier rounds of tariffs, they apply even to goods that currently qualify for duty free treatment under the Canada United States Mexico Agreement.
The timing has alarmed economists and labour groups. Statistics Canada recorded a national unemployment rate of 6.5 percent in June, with manufacturing among the hardest hit sectors. Roughly 61,000 manufacturing jobs have disappeared since a recent employment peak in January 2025, a wave that has already claimed positions at steelmakers, auto parts suppliers and truck manufacturers across Ontario and Quebec.
Prime Minister Mark Carney called the new duties disappointing and said Ottawa remains ready to engage intensively with Washington to resolve outstanding issues. His government has pointed to a broader strategy of diversifying Canadian trade beyond reliance on the United States, including a newly concluded agreement with the United Arab Emirates and the free trade negotiations recently launched with Turkiye.
Trade lawyers and industry groups are urging affected companies to review the full list of covered products before the August 19 deadline and to prepare for the compliance changes that come with it, including new rules affecting goods held in foreign trade zones. For workers in export dependent communities, the coming weeks bring renewed uncertainty about whether further layoffs are ahead.
This is a developing trade story; further details on the affected product list are expected in the coming weeks.
