Environment Canada has issued a winter storm watch for the Greater Toronto Area and much of southern Ontario
The snow will start Monday evening for the Greater Toronto Area and Golden Horseshoe, continuing through the overnight. Freezing rain and ice pellets will likely spread from Mississauga, Brampton and Oakville areas to London and Sarnia and north to Innisfil. The snow will also begin for Bruce Peninsula and southern portions of Georgian Bay. While, the freezing rain changes over to rain through southwestern Ontario.
As roads become covered visibility could drop to near zero, deteriorating travel conditions rapidly. The lake-effect snow could impact roads like the QEW corridor of western GTA, with easterly winds gusting up to 70 km/h.
On its website Sunday, Air Canada said passengers with bookings to and from Toronto, Montreal and Ottawa on Monday or Tuesday could change their flights without penalty in light of the expected weather.
