Canadian manufacturers facing some of the steepest U.S. tariffs are also operating on some of the thinnest profit margins, leaving them with less room to absorb the costs and disruptions of trade disputes and other economic pressures.
Canada’s automotive and steel industries have faced production disruptions and layoffs, while the petroleum sector, with its much higher profit margins, has faced fewer direct consequences.
Statistics Canada data show that motor vehicle parts manufacturers recorded a profit margin of 4 percent in the second quarter of 2026, compared with 7 percent for primary and fabricated metal producers, and 15 percent for petroleum product manufacturers. Pharmaceutical and paint manufacturers recorded one of the highest margins, at 18 percent.
Canada’s automotive industry relies on supply chains that cross the U.S. border repeatedly, with parts and components moving between plants before vehicles are finished. Tariffs can therefore affect manufacturers even when their own products are exempt, disrupting production schedules, increasing costs, and complicating investment decisions.
Automotive Among Lowest-Margin Industries
Statistics Canada data show that motor vehicle parts manufacturers recorded $8.4 billion in revenue in the second quarter, while other transportation equipment manufacturing sector, including aerospace, rail, and ship, reported $13.9 billion in revenue and a profit margin of 4 percent.
Primary and fabricated metal product manufacturers, a category that includes steel and aluminum producers, recorded a 7 percent profit margin. The industry has faced some of the steepest U.S. tariffs imposed on Canadian products.
Plastics and rubber manufacturers posted an 8 percent margin, placing them in the middle of the manufacturing industries examined.
Profit margins indicate how much of a company’s revenue remains as profit after expenses, which can act as a measure of an industry’s ability to withstand financial pressure. In general, a manufacturer operating on a 4 percent margin has less room to absorb rising costs or falling sales than one earning a 15 percent margin.
Petroleum and Pharmaceuticals Lead
At the other end of the spectrum, pharmaceutical, paint, and other chemical product manufacturers recorded an 18 percent profit margin, while petroleum product manufacturers posted a 15 percent margin.
Computer and electronic equipment producers recorded a 12 percent margin.
Canada’s petroleum industry has faced a different economic environment than automotive and metals manufacturing. Energy products have generally dodged additional U.S. tariffs, although the sector remains exposed to fluctuations in commodity prices and broader economic conditions, particularly during conflicts in the Middle East.
The Statistics Canada figures don’t suggest that Washington deliberately targeted industries with thinner margins. They do, however, show that some of the Canadian manufacturers facing the greatest trade pressures are operating with less financial cushion than other sectors.
