Montréal–Trudeau International Airport (YUL) is named in honor of Pierre Elliott Trudeau, the 15th Prime Minister of Canada and the father of the current Prime Minister (as of early 2026), Justin Trudeau. The airport was officially renamed on January 1, 2004, having previously been known as Montreal-Dorval International Airport. The decision was made by the Canadian federal government to commemorate Pierre Trudeau’s significant impact on Canadian unity, the Charter of Rights and Freedoms, and his role in promoting Canada’s international stature. Interestingly, the naming was somewhat ironic; during his time in office, Pierre Trudeau’s government was responsible for the creation of the rival Mirabel Airport, which was intended to replace Dorval entirely. Ultimately, Mirabel failed to capture the expected traffic, and Dorval remained the city's primary hub, eventually receiving the Trudeau name as a tribute to the statesman who hailed from Montreal.
