Its looking a lot like AC will be deploying CR9's on the YYC-YQR route as of May and moving it up to 3 x Daily. If this really does happen it would be fantastic! I think it could bring down the flight time by 20-25% which racks up especially on the Westbound segment.
Story has it AC are moving some of their Q400 fleet back East for those shorter hops.
