Tariffs and Turmoil: How a Canada–U.S. Trade War Would Reshape Canadian Employment

Tariffs may begin as political leverage, but their real cost is economic and often paid in jobs.

As Canada faces growing uncertainty around U.S. trade policy, including the threat of renewed tariffs on steel, aluminum, automotive parts, and agricultural exports, the stakes for the Canadian labour market are rising. While headlines focus on foreign policy and diplomacy, the deeper impact is felt at home, on factory floors, supply chains, and job postings.

Here’s what a renewed tariff war with the United States could mean for employment in Canada.

1. Immediate Impact: Sector-Specific Job Losses

The United States is Canada’s largest trading partner, accounting for nearly 75% of total exports. Tariffs on Canadian goods entering the U.S. reduce demand by making them more expensive for American buyers. The effect is especially acute in:

• • Automotive manufacturing (Ontario)
    
  • Steel and aluminum production (Ontario, Quebec)
    
  • Agricultural exports (Prairies and Atlantic Canada)
    
  • Lumber and forest products (British Columbia)
    

If tariffs return or increase, Canadian exporters will likely face cancelled orders, reduced output, and frozen hiring, eventually resulting in layoffs.

Case in point: In 2018, when the U.S. imposed tariffs on Canadian steel and aluminum, estimates by the Canadian Steel Producers Association suggested over 6,000 direct and indirect jobs were at risk.

2. Supply Chain Disruptions and Workforce Insecurity

Tariffs do not just affect exporters. They ripple across entire supply chains:

• • Parts suppliers, logistics firms, and warehouse operators may see declining volumes
    
  • Professional services (engineering, marketing, and sales) tied to affected sectors may contract
    
  • Contract and seasonal workers will face heightened insecurity as employers cut flexible labour first
    

The result is a chilling effect on employment certainty, even in sectors not directly subject to tariffs.

3. Decline in Business Confidence and Hiring Activity

Tariff uncertainty leads to hesitation in capital investment and hiring. Employers in export-heavy industries tend to:

• • Delay or cancel expansion plans
    
  • Avoid permanent hires in favour of temporary or casual labour
    
  • Freeze new recruitment until trade terms are clarified.
    

According to a 2024 survey by the Business Council of Canada, 64% of exporting firms said they would reconsider their hiring plans if tariffs resumed under a more protectionist U.S. administration.

4. Regional Disparities in Employment Losses

Tariffs disproportionately impact provinces with strong trade linkages to U.S. markets:

• • Ontario (automotive, tech components, machinery)
    
  • Quebec (aluminum, aerospace)
    
  • British Columbia (lumber, mining equipment)
    
  • Prairie provinces (grain, beef, canola exports)
    

In these provinces, job losses will be more concentrated and visible, increasing regional inequality and straining provincial labour supports.

5. Long-Term Risks: Talent Drain and Deindustrialization

If tariffs are sustained, companies may:

• • Shift operations to the U.S. to avoid cross-border penalties
    
  • Relocate high-value functions (engineering, R&D) closer to American clients
    
  • Rely more on automation and less on human labour to offset costs
    

These trends can result in a long-term decline in domestic job creation, especially in advanced manufacturing and tech-enabled trades, driving skilled workers to seek opportunities abroad, often in the very markets Canada is losing access to.

Conclusion: Tariffs Hurt Jobs Even Without a Trade War

While tariffs are often framed as tools of trade negotiation, their domestic effects on employment are immediate and regressive. In a deeply interconnected North American economy, tariff escalation with the U.S. would jeopardize not just GDP, but the livelihoods of hundreds of thousands of Canadians across industries and regions.

Canada’s labour market resilience depends not only on innovation and immigration but also on the stability of our trading relationships. For policymakers, defending open access to the U.S. market is not just a diplomatic priority. It is an employment strategy.
