In its early years, what is now Toronto Pearson International Airport was known as the Malton Airport. Established in 1937, it was built by the Toronto Harbour Commission and was originally intended to serve as an alternate airfield to the downtown Toronto Island Airport (now known as Billy Bishop Toronto City Airport). Pearson instead became the primary airport for the Greater Toronto Area and the entire Golden Horseshoe region. Today, Toronto Pearson is the largest and busiest airport in Canada and is among the busiest airports in the world.
