The CUSMA Precipice: A Systemic Threat to the Canadian Labor Market

As Canada-U.S. Trade Minister Dominic LeBlanc and chief trade negotiator Janice Charette return to Washington to meet with United States Trade Representative Jamieson Greer, the stakes have shifted from diplomatic friction to a systemic economic threat. While Ottawa frames these discussions as a defense of national interests, a new report suggests the potential fallout from a CUSMA collapse would be catastrophic for the Canadian workforce.

As CityNews Toronto first reported, a study conducted by Oxford Economics for the Canadian American Business Council warns that Canada could lose 102,000 jobs if the Canada-U.S.-Mexico agreement is terminated. The risk is not confined to a single sector; while manufacturing would be hit hardest by tariffs, the report notes that the service sector would suffer as reduced disposable income lowers consumer spending and diminished trade reduces demand for professional services, construction, and transportation.

The industrial casualties would be widespread. Oxford Economics identifies the most vulnerable sectors as electronics, chemicals, wood and paper products, machinery, metals, and autos. Geographically, the impact would be most acute in Quebec, Ontario, Manitoba, and New Brunswick.

This is not merely a theoretical risk. CityNews Toronto reports that a new round of 50 per cent American tariffs on various Canadian goods is scheduled for Aug. 19. Critically, these tariffs contain no exemptions for goods that comply with CUSMA, signaling a departure from previous trade dynamics.

The human cost of this instability is what concerns labor advocates most. Bea Bruske, president of the Canadian Labour Congress, has cautioned that Canadian workers cannot be used as "bargaining chips" in a trade war. While Bruske argues that Canada must not sign a "bad deal" simply because President Donald Trump threatens to exit the agreement, she explicitly questioned the government's readiness, asking what the specific plan is to protect communities and workers if the U.S. walks away.

The scale of the dependency is staggering. The Oxford Economics report estimates that approximately 2.5 million jobs in Canada are tied to the bilateral trade relationship. Beyond immediate job losses, the report warns of "substantial transition costs" as businesses are forced to dismantle and rebuild complex supply chains developed over decades.

Ottawa has attempted to pivot toward diversification. Julian Karaguesian, a McGill University lecturer and former Finance Canada special adviser, notes that while U.S. trade has declined, trade with non-U.S. partners is rising. This aligns with a Liberal government goal to double non-U.S. exports over ten years. Indeed, Global Affairs Canada spokesperson Samantha Lafleur stated that non-U.S. exports of services and goods totaled $96.2 billion in the first quarter of this year, and a spring economic update noted a $33 billion increase in such exports in 2025 over 2024.

However, diversification is a long-term strategy for a short-term crisis. The Oxford Economics report emphasizes that a successful renegotiation would not only protect jobs but create 98,000 Canadian positions and add approximately $846 CAD per Canadian household annually. Conversely, the report warns that the current status quo is not a neutral baseline, as existing tariffs already stifle export growth and keep unemployment elevated.

As LeBlanc and Charette negotiate, the gap between Ottawa's diplomatic optimism and the stark reality of the labor market's vulnerability remains a critical point of failure.
