Canada is preparing to celebrate its 158th birthday on July 1, 2025. Known as Canada Day, the holiday marks the formation of the Canadian Confederation under the British Colonial Empire. This year, travel trends show a shift towards domestic destinations amid recent political events.
According to Cirium, an aviation analytics company, the busiest air routes for Canada Day are from major U.S. cities near the border. Toronto and Vancouver airports will see most of this traffic, with Montreal taking one spot in the top ten. "Toronto’s Pearson International Airport (YYZ) has the lion’s share," reflecting its status as Canada's largest city and proximity to Chicago and New York.
Seattle-Tacoma International Airport is another key hub for travelers heading to Vancouver. Delta Air Lines offers nearly 3,500 seats from Seattle to Vancouver International. The route benefits from Seattle's large population and many connecting flights.
