The snow has largely fallen and the digging and ploughing has begun across the Greater Toronto and Hamilton area after a major winter storm overnight.
Environment Canada said a snowfall warning remained for Toronto and much of York Region until after 7 a.m., and a winter storm warning was in effect for Halton, Hamilton and Niagara.
Meteorologists said Toronto could see up to a further four centimetres of snow by late Tuesday morning.
The TTC warned that all express bus service was cancelled and streetcar lines would see major delays throughout the morning due to the snowfall.
Bitterly cold temperatures in Toronto have prompted the city’s medical officer of health to issue an extreme cold weather alert today. Toronto will see a high of -10 C but the temperature will feel closer to -20 this morning with the wind chill.
Winter warnings are gradually dropping across parts of Ontario after a potent storm ramped up in intensity through the overnight hours on Monday and pushed heavy snow into the region Tuesday morning.
Drivers are still being warned to postpone any non-essential travel until conditions improve, with very poor visibility reported in areas of blowing snow.
A widespread 15-30 cm of snow is forecast across the region before it eventually tapers Tuesday afternoon, combined with wind gusts of 50+ km/h, making for dangerous conditions on many major routes.
