Montreal Metropolitan Airport (MET) in Longueuil operates as a counterpoint to the scale and sprawl of Trudeau. Built on an existing airfield long used for private and regional aviation, the site has been reworked to handle scheduled commercial service with a focus on short- and medium-haul routes.

The terminal is compact by design—just over 20,000 square metres—with a layout that keeps most of the process within a short walk. Nine boarding bridges, a few dozen check-in counters, and a small security footprint reflect that positioning, as does a passenger capacity capped at around four million annually. Airlines operating here tend toward regional and low-cost carriers using smaller aircraft.

Rather than expanding into a full-service international hub, MET leans into efficiency: quick curb-to-gate transitions, minimal retail, and infrastructure calibrated for volume without congestion. It’s an airport built around throughput, not spectacle.
