I remember a press release on AC's site this summer saying that YTZ-YUL service would be restored, but... aircanada.com still doesn't recognize YTZ, even when Porter Airlines is taking reservations for November flights to YOW. What gives?

Big political stink between the Port Authourity and Jazz compounded by the fact Porter has the Terminal building all locked in for themselves.

Essentially Jazz was booted out for not renogotiating fairly and in good faith and the port folks wanting to see the airport thrive are more than willing to help Porter stave off off any predatory Jazz tactics.
