Posthaste: Here's how Trump's fresh wave of tariffs will hit Canada the hardest

Donald Trump’s fresh wave of tariffs that took effect this weekend could cost tens of thousands of jobs across the country, according to a well-known economist.

Trevor Tombe, a professor of economics at the University of Calgary, estimates that the new levies could result in nearly 90,000 jobs lost — about 0.4 per cent of Canada’s labour force — many of them in provinces and sectors not directly exposed to the tariffs.

The new section-338 tariffs landed Saturday after Prime Minister Mark Carney suspended trade talks with the United States just hours before the Friday night deadline.

The 50-per-cent levies on $28-billion worth of Canadian goods covers a wide range of products including machinery and electronics, furniture, alcohol, food and clothing. Carney has pledged to match the U.S. tariffs dollar for dollar.

Tombe, writing for The Hub, estimates that if the tariffs remain in place and sales of the affected goods drop that 52,000 jobs in Canada are directly at risk. Another 35,000 jobs lost in suppliers and service providers to the exporters brings the total to over 87,000. Job losses on that scale would push the country’s unemployment rate from 6.4 per cent to 6.8, he said.

Ontario, the country’s manufacturing hub, will be hit the hardest. Tombe estimates this province could lose 36,000 jobs, Quebec, 18,000, British Columbia, 11,000 and Alberta, 9,000.

Alberta stands out as an example of the wide-reaching impact of the tariffs, he said. Even though its own exports are barely affected by the new levies, the province would lose jobs as services supporting exporters elsewhere are disrupted.

Despite this, economists, including Tombe, do not expect the new tariffs to derail Canada’s economy. Estimates on the hit to gross domestic product range from a decline of 0.5 per cent to a couple of tenths of a percentage point.

The $28 billion covers just 5 per cent of the goods Canada exports to the United States, or about 0.8 per cent of its GDP.

Royal Bank of Canada economists estimate that Canada’s average effective tariff rate rises to about six per cent from three per cent, “no longer the lowest among major U.S. trade partners, but still below the average U.S. tariff rate on imports from all countries (close to 7 per cent).”

The targeted exports do include some products previously exempted under the Canada-United-States-Mexico Agreement (CUSMA), but 80 per cent of Canada’s exports to the U.S. will remain duty-free.

One big unknown is how this latest development will affect business sentiment, which was just starting to pick up again.

While the impact on trade “sounds digestible in the aggregate, some specific businesses/industries would be hit extremely hard,” wrote Robert Kavcic, senior economist at BMO Capital Markets.
