The distance between downtown Toronto and its primary international gateway, Toronto Pearson International Airport (YYZ), is approximately 27 kilometers (17 miles). In 2026, the travel time depends heavily on your mode of transport and the city's notorious traffic. By car or rideshare, the journey can take anywhere from 25 minutes in light traffic to over an hour during the morning or afternoon rush along the Gardiner Expressway or Highway 427. The most efficient and predictable way to cover the distance is via the UP Express (Union Pearson Express) train, which departs from Union Station in the heart of downtown. The train takes exactly 25 minutes and runs every 15 minutes, making it the preferred choice for business travelers and tourists alike. If you are flying via the smaller Billy Bishop Toronto City Airport (YTZ), the distance is much shorter—it is located on the Toronto Islands, just a few minutes' ferry ride or pedestrian tunnel walk from the foot of Bathurst Street in the downtown core.
