Billy Bishop Toronto City Airport — Toronto, Canada

Billy Bishop Toronto City Airport (YTZ) occupies Toronto Island, just offshore from downtown Toronto, Ontario, and is named after World War I flying ace Billy Bishop. Uniquely positioned within walking distance of the city's financial district via a pedestrian tunnel, YTZ primarily serves business travelers seeking a faster alternative to Toronto Pearson International Airport. The airport is operated largely by regional carriers flying short-haul routes to destinations across Canada and parts of the northeastern United States. Its short runway and urban location have made it a subject of ongoing debate regarding noise, expansion, and jet aircraft restrictions. Despite these constraints, YTZ remains one of Canada's busiest airports by passenger volume.
