Any of those places can expect anywhere from 10 to 20 centimetres of snow on Sunday night going into Monday morning. Weather Canada says if you're in one of those regions, you should be wary of "quickly changing and deteriorating" travelling conditions. "Rapidly accumulating snow could make travel difficult over some locations." Luckily (or not so luckily, depending on how much you like sledding), most of southern Ontario is free from any snow-related weather advisories. But that's not to say snow is out of the cards. In Toronto, for instance, Weather Canada says there's a 40% chance of flurries on Monday, when temperatures will dip to -9 C.
