The Mirabel International Airport was opened in 1975 as replacement for the existing Dorval Airport. Costing $1.8 billion in today’s money, it was a huge drag. On one hand, it was 26 miles from downtown Montreal, so it had very little traffic from passengers.

By the early 00’s, airlines had abandoned the airport and Dorval was expanded and renamed Trudeau Airport. The terminal has since been demolished and the existing property is used for cargo flights and film sets.
