The chamber alleges WestJet and Air Canada have engaged in anticompetitive behaviour through a strategy to reduce competition intensity on certain regional Canadian routes.
It says the routes from Saskatchewan are critical not just for travel to and from Calgary, but also for connecting flights from the key hub.
Air Canada says it rejects any allegations of anticompetitive conduct, noting that it continues to serve Saskatoon and Regina with daily flights to Vancouver and Toronto, and beginning on June 1 to Montreal.
WestJet also rejected the allegations and says it is committed to serving Saskatchewan.
The Competition Bureau confirmed that it received the chamber’s complaint, but said it is required to work confidentially and was unable to say if it would be investigating.
