They are also doing YYC-PHX, both YYC and YEG are daily.
Here is the press release:

It mentions RSW increasing to 5x weekly, MIA to 4x weekly and NAS to 2x weekly, which have been posted here previously.
It also says CUN is going to 10x weekly, but I don't see it loaded yet, just daily service. Perhaps they're including the 3x weekly TS flights in that count - although they aren't bookable through Porter.
I still don't see YOW-PHX loaded either, so it indeed appears to have gotten the axe.
