CANADA AND America’s economies are joined on the hip. Some $2bn of commerce and 400,000 folks cross their 9,000km of shared border on daily basis. Canadians on the west coast do extra day journeys to close by Seattle than to distant Toronto. No marvel, then, that the 2 economies have largely moved in lockstep in latest a long time: between 2009 and 2019 America’s GDP grew by 27%; Canada’s expanded by 25%.
