Peter Navarro is the White House Senior Counselor for Trade and Manufacturing. He submitted this to National Post to articulate the U.S. view on trade with Canada. Read the Post’s Carson Jerema’s response.

Article content

Canada has long cultivated the image of America’s friendly, free-trading neighbor. The reality is less polite.

Behind the maple-leaf branding is a protectionist system that singles out American farmers, distillers, automakers, and workers. Canada demands access to the American market while reserving the right to close its own when competition becomes inconvenient.

Article content

President Donald Trump is ending that one-way arrangement with three proclamations imposing additional 50 per cent tariffs in response to Canada’s obstruction of American dairy exports, government-directed blockade of American alcoholic beverages, and punitive tariff system targeting U.S. made vehicles.

Article content

Article content

The authority is Section 338 of the Tariff Act of 1930. It permits additional duties of up to 50 per cent when another country discriminates against American commerce or favourrs competitors. The duties take effect 30 days after the proclamations, giving Canada time to end them.

Article content

These are not blanket tariffs. Each proclamation targets selected products to offset a burden on American commerce.

Article content

Section 338 authorizes the President to offset the full burden, not merely mirror the offending product. Tariffs on Canadian dairy, alcohol, or autos alone would not equal the damage caused by Canada’s measures, while autos and auto parts are already covered by a separate Section 232 regime. The proclamations therefore extend to additional Canadian goods. The goal is a comparable burden until Ottawa lifts its burden on American producers. This is reciprocal trade enforcement, not economic aggression.

Consider dairy.

Article content

Article content

Canada’s supply-management fortress uses production quotas, administered prices, import controls, and prohibitive over-quota tariffs. Its tariff schedule imposes rates of approximately 241 per cent on some fluid milk, 245.5 per cent on cheese, and 298.5 per cent on butter.

Article content

These are megatariffs designed to stop trade.

Article content

President Trump’s United States-Mexico-Canada Agreement secured additional quota access for American dairy producers. Canada then manipulated that access.

Article content

Under Canada’s allocation rules for the USMCA cheese quota, retailers cannot receive allocations. Yet under Canada’s agreement with the European Union, retailers may participate in the comparable quota. European cheese therefore receives access denied to American cheese.

Article content

That is discrimination by nationality.

Article content

The dairy proclamation answers with an additional 50 percent tariff on targeted Canadian goods, including milk powders, whey products, milk proteins, lactose, and casein.

Article content

Next comes alcoholic beverages.

Article content

Beginning in March 2025, Canadian provinces and territories used their control over wholesale purchasing and retail distribution to remove American beer, wine, bourbon, whiskey, and other beverages from Canadian commerce.
