Toronto’s main international airport (YYZ) is named in honor of Lester B. Pearson, the 14th Prime Minister of Canada. The facility was officially renamed "Lester B. Pearson International Airport" on January 2, 1984, to commemorate the Toronto-born statesman who won the 1957 Nobel Peace Prize for his role in resolving the Suez Crisis through the creation of the first UN Peacekeeping force. Before the name change, it was simply known as "Toronto International Airport," and before that, "Malton Airport" due to its location in the town of Malton. Pearson is Canada’s largest and busiest airport, serving as the primary gateway for the Golden Horseshoe region. Interestingly, while the airport is named after Pearson, its famous IATA code "YYZ" actually predates the naming; it originated from the railway station code for Malton. In 2026, the airport continues to be a central hub for Air Canada and WestJet, maintaining the legacy of the man who is also credited with introducing Canada’s iconic maple leaf flag during his time as Prime Minister in the mid-1960s.
