You've apparently never experienced a Canadian winter.
Montreal has the Olympic Stadium and Toronto has the Rogers Centre, so it could work fine. Just a bummer that they won't get to play in their "home" parks.

It makes sense, but it sucks for teams like Montreal, Toronto, and Chicago, who will have to play winter games even with the 6-week break.
These next two qualifiers are a chance for players like Johannsson, Diskerud, Kljestan, and Cameron to really state their cases. All are potential starters in Brazil, imo.
