Trump has repeatedly criticised Canada’s supply management system for dairy, eggs and poultry. That framework uses production quotas, regulated prices and import limits, which he argues disadvantage US farmers.
The latest measures are also likely to increase pressure on Canadian leaders to reject demands for concessions, French said. In other words, another round of economic pressure may make compromise harder rather than easier, an outcome trade disputes have been known to produce with impressive consistency.
How did the US-Canada trade dispute escalate?
The new restrictions mark another step in a trade conflict that has run for months between two countries with deeply connected economies and a long history as allies.
More than two-thirds of Canada’s total exports generally go to the United States. Canada, meanwhile, is the second-largest US trading partner after Mexico, although American exporters sell into a broader range of markets.
Last month, the White House imposed 50% tariffs on about $20bn (£14.8bn) of Canadian goods after several rounds of negotiations failed. Those duties affected Canadian furniture and wine producers, along with companies selling sporting and fishing equipment.
Ottawa answered with matching tariffs on US products, including:
Those counter-duties took effect just after midnight on Tuesday, prompting Washington’s latest response.
On Monday, Trump also suggested more restrictions could follow. He warned Canadian aircraft manufacturer Bombardier that it would lose access to the US market unless it moved production to the United States.
Who pays for the trade war?
Businesses on both sides of the border have warned that the dispute could raise prices and reduce customer demand. Scott French said the conflict would be “costly for both sides due to the historical level of integration of the North American economy”. Consumers in both countries, he added, would be “the biggest losers”.
Trump has long argued that tariffs can reduce trade imbalances between the US and other countries. His broad tariff campaign has also strained relations with several traditional American allies, which is one way to test a friendship while increasing the price of cheese.
Canadian consumers have already organised a large boycott of American products, particularly alcohol. Some US brands disappeared from shop shelves after Trump began his global tariff campaign last year.
Trade specialist Deborah Elms of the Hinrich Foundation said the new import restrictions could have a “strong” effect on individual Canadian companies that depend on American buyers. Early estimates, however, suggest the overall impact may be relatively modest, covering about $1bn in trade.
Could Washington and Ottawa resume talks?
Elms expects Canada to “hold course for now” while adjusting support programmes for businesses affected by the additional US measures.
The unresolved issue is how the two governments return to negotiations. No new discussions have been arranged since the August breakdown, despite public statements from both sides that they still want an agreement.
“The bigger question is what it will take for the two sides to sit back down together,” Elms said. “The language in these proclamations, as an example, isn’t helpful in getting to the negotiating table.”
For now, tariffs and bans are doing most of the talking. Companies and consumers will receive the bill while officials consider when to resume the conversation.
