Mapping Tariffs visualizes the impact of U.S. tariffs on Canadian businesses. “Since May 2025, Tara Vinodrai and Karen Chapple have led a team of researchers at the School of Cities to develop interactive mapping and visualization tools that measure and explore the potential impacts of tariffs on jobs and businesses across Canadian cities and communities at the neighbourhood and city level. Our tools illustrate the highly localized and uneven potential impacts of U.S. tariffs reflecting Canada’s underlying urban, regional and sectoral specializations.” CTV News coverage.
