ECCC says communities near the Niagara Escarpment and the Dundalk Highlands may receive even more than 35 cm.
The snow is starting around noon on Saturday and expected to continued into Sunday evening, so make your travel plans accordingly. Basically, we are being advised to avoid the roads as much as possible over the next day and a half.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to ONstorm@ec.gc.ca or post reports on X using #ONStorm.
So, Family Day Monday should be epic for skiing and tobogganing enthusiasts, but Sunday might be better suited for outdoor activities that don’t require driving; shovelling the driveway for example, or perhaps playing games, puzzling or reading.
Be safe everyone!
