Summary
Former Bank of England Governor Mark Carney has voiced a strong response to Donald Trump’s recent threat to impose new tariffs on Canada should he return to the U.S. presidency. During a live segment, Carney emphasized the importance of multilateral trade agreements, such as USMCA (United States-Mexico-Canada Agreement), warning that Trump’s proposed protectionist measures would destabilize long-standing trade relationships between the two countries.
Carney pointed out that tariffs like those Trump threatens undermine economic stability and investor confidence. He stressed that Canada relies on effective trade frameworks to maintain growth, and revisiting past policies—especially those settled by USMCA in 2020—could unravel key gains made in North American trade.
Trump’s history with tariffs during his first term included levies on Canadian steel and aluminum, which sparked trade tensions. Carney warned that similar actions could lead to retaliatory measures and reduced cross-border collaboration. The ex-central bank chief also cautioned that such policies are “short-sighted” and tend to inflate costs for American businesses and consumers alike.
In his address, Carney championed diplomacy and pointed out that Canada has remained a dependable trade partner that abides by international rules. His tone, while diplomatic, signaled growing concern among Canadian policymakers about the direction of U.S. politics as the 2024 election looms.
While Carney didn’t name specific policies for Canada to adopt in response, he highlighted that continued engagement with American stakeholders and diversified trade ties—particularly with Europe and Asia—are among the best defenses against isolationist policies.
Analysis
Mark Carney’s reaction isn’t just a political statement—it’s an economic warning. As a seasoned economist and former central banker, he understands the ramifications of tariff escalation better than most. His comments suggest that if Trump wins in 2024 and enacts new tariffs, the economic consequences could be felt across industries in both countries.
Here’s why this matters:
- Trade agreements like USMCA were designed to prevent exactly this scenario: unilateral, politically motivated trade barriers that disrupt supply chains.
- Canada’s economy is export-driven, with nearly three-quarters of its exports going to the U.S. New tariffs would damage core sectors such as aluminum, steel, automotive, and agriculture.
- Investors and companies dislike uncertainty. Tariff threats could result in delayed investments, job losses, and increased supply chain costs.
A potential second Trump term could revive a combative approach to trade. This raises concerns similar to those voiced in 2018 when Canada faced steep U.S. tariffs. Businesses and trade organizations would have to brace for disrupted pricing, reduced competitiveness, and higher consumer costs.
Protectionism is a tax on your own people—and it’s not a sustainable basis for prosperity.

Long-term, Canada may need to accelerate trade diversification. Carney subtly hinted at this, suggesting that increased reliance on markets in Europe and Asia could insulate the country from the volatility of U.S. politics.
Industry experts tend to agree: while Trump tapped into real grievances regarding manufacturing job losses, trade barriers are a blunt tool. The Canadian Chamber of Commerce reiterated in a recent report that “stable, rules-based trade” is the only viable long-term strategy for prosperity.
As 2024 approaches, this will be a key area of focus in Canadian economic policy circles. Should Trump win, Canada may be forced to rework its strategy from collaboration to containment.
