NW has traditionally been a larger player in Western Canada through flights from its MSP hub than in Central and Eastern Canada. I wonder if transborder flights from places like YYC, YEG, YWG, YVR and even places like YUL, YQB and YHZ have been as affected as flights from YYZ. NW seems to have gotten most of their Western Canada flights out reasonably on time yesterday, canceling only 1 YWG-MSP flight. YYZ seems to be the huge mess - especially Air Canada's Terminal 1. That's not surprising, given that YYZ offers more trans-border flights than any other airport in the country.
