Researchers at the University of Torontoβs School of Cities have launched Mapping Tariffs β an interactive tool showing how vulnerable each Canadian city is to U.S. tariffs. πΊοΈ
Key findings:
Toronto: 3,027 businesses (3.2%) and roughly 66,000 employees (4%) directly exposed
Vaughan: ~1,000 businesses (5.7%), 32,555 employees who work there (12%), and nearly 12,000 workers who live there (6.7%)
Windsor: 4.5% of businesses impacted; ~12,100 employees (11.6%)
Toronto CMA (Ajax to Milton): 7.3% of businesses potentially impacted; 200,000+ employees (13.5%)
The map has been continuously updated with each round of tariffs, most recently on Sept. 1. Researchers are currently working on a revision to reflect changes to Section 338 tariffs on alcohol and dairy.
βItβs clear in all of our analysis that this new round of tariffs basically widens and deepens the effects on Canadian cities and neighbourhoods,β said Tara Vinodrai, a professor at U of T. βToronto is not immune from that.β
