The Greater Toronto Area has a couple of chances to see snow on Monday, and up to five centimetres could fall each time.
Lake-effect flurries are forecast from Monday morning to early afternoon on the north shore of the Golden Horseshoe, including the Greater Toronto Area.
Environment Canada says the bands of snow could be heavy at times and reduce visibility to near zero. Up to five centimetres of snow is possible.
Later in the day, another two to five centimetres of snow could fall as an Alberta clipper passes through southern Ontario. The snow is expected Monday afternoon to Tuesday.
The Alberta Clipper will first coat northern Ontario with snow. Northwestern Ontario could see five to ten centimetres on Monday morning.
North of Lake Superior, 15 cm of snow may fall as snow squalls boost the total amount. Environment Canada says drivers should prepare for winter driving conditions and low visibility.
