Montréal–Mirabel International Airport
airport in Mirabel, Quebec, Canada
Montréal–Mirabel International Airport (IATA: YMX, ICAO: CYMX), originally called Montréal International Airport, widely known as Mirabel and branded as YMX International Aerocity of Mirabel, is a cargo and former international passenger airport in Mirabel, Quebec, Canada, 21 nautical miles (39 km; 24 mi) northwest of Montreal. It opened on October 4, 1975, and the last commercial passenger flight took off on October 31, 2004.
The airport is mainly used for cargo flights, but it is also home to medevac and general aviation flights, and hosts a manufacturing plant for Airbus, where final assembly of the Airbus A220 (formerly Bombardier CSeries) is conducted. Bombardier Aviation produced the Bombardier CRJ700 series of regional jets at the factory until early 2021. The former passenger terminal apron is now a racing course, and the terminal building was demolished in 2016.
Prior to the demolition of the passenger terminal, Montréal–Mirabel International Airport was classified as an airport of entry (AOE) by Nav Canada and was staffed by the Canada Border Services Agency (CBSA). A smaller AOE for general aviation with no more than 15 people on board is still available from Hélibellule, Nolinor, and Mirajet. In addition it is one of ten Canadian airport classified as an airport of entry for cargo flights. It is part of the National Airports System and it was one of two airports in Canada with sufficient right-of-way that can be expanded to accommodate 50 million passengers per year, the other being Toronto Pearson International Airport. A lack of traffic meant that Mirabel was never expanded beyond its first phase.
This brief starts where responsible research should: with the source description of “Montréal–Mirabel International Airport” as airport in Mirabel, Quebec, Canada. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the places & architecture register because the source frames it as airport in Mirabel, Quebec, Canada. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated Sep 22, 2026. The linked authority identifier is Q794552. Authority coordinates are 45.682, -74.005. None of the 3 selected statements returned an explicit reference. The first chronological checks are 1975, 2004, 2021 and 2016.
Architectural summaries often privilege surviving fabric and can understate demolished phases, contested use or displaced communities. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
