All these flights are on CRJ, either a 200 or 700 better choice, not great. Look for the CRJ 7/900 flights. First flight out of YYZ could have issues of the water tank/line freezing overnight if the plane is not stored properly during the winter. There have been many cases of no coffee or water in the lavatory. (Relax these are from different water system)

YYZ and MSP are two airports that deal with winter storms better than average.

If you can get on a flight with more time then your comfort zone is better.
