Parts of Ontario are about to get slammed with up to 20 cm of snow

After a messy mix of freezing rain, strong winds, and snow this week, southern and eastern Ontario are preparing for yet another wintry blast of weather. 

According to The Weather Network's latest report, a fast-moving low-pressure system is expected to bring more snowfall and strong winds across the region on Friday, with the potential for a second storm over the weekend. 

The system, which is pushing in from the West Coast, is set to deliver anywhere from five to 20 centimetres of snow to the province on Friday. The heavy precipitation is expected to kick off early Friday near the Lake Huron shores and reach the GTA by late morning. 

A clipper system is expected to move into the region Friday morning and continue through the evening. Snowfall totals of 5-10 cm are possible for Toronto, with up to 15 cm across parts of Southern Ontario.

"The heaviest snowfall occurs west of Toronto in the morning, with the GTA seeing its heaviest snow by mid-morning to lunch hour," the report reads. "Later, heavier snowfall shifts east to areas like Oshawa, Peterborough, and Kingston." 

Mild temperatures will mean cities like Toronto and Hamilton will experience a mix of both rain and wet snow, which will affect total accumulations. Make sure to keep your parkas and snowboots on hand, because snow is expected to return to Toronto on Friday evening, before finally tapering off by Saturday morning. 

Strong winds are also set to accompany the snow, resulting in reduced visibility, especially in areas around the GTA. 

"With strong winds and above-ground power infrastructure, some areas may see power outages due to downed power lines. Prepare for slowdowns during Friday's evening commute and stay updated on weather alerts," the report continues. 

On Saturday, we'll see a temporary break from the active weather, although temperatures will remain below seasonal averages. On Sunday, another system would bring "significant snow and rain," so if you have any errands you need to run, you might want to plan your outings for Saturday instead. 

Temperatures in Toronto are expected to range from a Friday morning low of -3 C to an afternoon high of 2 C, before dipping to -4 C on Saturday morning. 

According to The Weather Network's Spring 2026 forecast, Ontario will see periods of mild weather throughout March and April, although these breaks will likely be interrupted by cold snaps. In April, near normal or above normal precipitation is expected, which will undoubtedly include "more snow and ice for much of the province including Toronto, Ottawa, and Thunder Bay."
