I saw the following image on Airliners.net & Twitter regarding
possible Air Canada A220 routes for when they receive that aircraft starting in 2020.
As I expected, they don't list any "possible new routes" from YOW, but they do have YYT and YWG in red (meaning current routes) which I would be happy about. If YYT can go year-round and YWG can go back to mainline, that would be a positive in my opinion.
and
thread link for the curious.
