Page "Montréal-Mirabel International Airport" Paragraph 4

It is 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, though a lack of traffic meant that Mirabel was never expanded beyond its first phase.

It is one of only two non-capital airports with fewer than 200, 000 passengers a year to be part of the National Airports System.
