First Snow Possible in Ontario This Weekend as Cold Front Eyes GTA and Snowbelt

A warm-tilted seasonal outlook from Environment Canada sits alongside short-range guidance calling for GTA flurries.

Overview

  • Environment Canada says Sunday, November 9 is the most likely window for the GTA to see flurries with a passing low-pressure system bringing rain and wet snow.
  • Northern parts of the GTA and higher elevations toward Lake Simcoe are more likely to see mainly snow and localized accumulation, while lakeshore areas favor a rain–snow mix.
  • Forecasters expect little to no sticking in Toronto’s core because ground temperatures remain too warm, with any early snow most likely limited to grassy surfaces north of the city.
  • The Weather Network projects a significant weekend cooldown and says parts of Ontario, including the snowbelt, could see the first accumulating snow and potential lake-effect early next week.
  • ECCC’s November–January outlook leans mild for Southern Ontario and does not forecast seasonal snowfall amounts, and officials say model agreement on the weekend system should sharpen by Thursday or Friday.
