Ottawa Braces for Season's Biggest Snowstorm: Up to 25 cm Forecast
Major Snowstorm to Dump 25 cm on Ottawa

Residents of Canada's capital are preparing for a major winter blast, as forecasters warn the most significant snowstorm of the season is set to hit Ottawa. Environment Canada has issued a weather alert, predicting the system could deposit as much as 25 centimetres of snow on the city.

Storm Details and Timeline

The weather agency indicates the snow is expected to begin falling on Wednesday, January 15, 2026, and continue into Thursday. The forecast suggests a prolonged period of snowfall, which will lead to rapidly accumulating snow on roads and sidewalks. This event is poised to easily surpass any previous snowfall totals witnessed in the region this winter.

Impacts and Preparations Underway

The impending storm is expected to cause considerable disruption to the morning and evening commutes on both days. City officials have likely activated their winter road maintenance plans. As seen in a file photo from Sunday, November 9, 2025, City of Ottawa snowplows will be deployed in force to clear major arteries, but residents should anticipate slower travel and potential delays on public transit.

Environment Canada's warning serves as the primary source for this forecast, emphasizing the potential for heavy, sustained snowfall. Residents are advised to plan ahead, consider postponing non-essential travel, and ensure they have necessary supplies at home.

Context of a Variable Winter

This major snow event for Eastern Canada contrasts sharply with weather patterns being reported in other parts of the country. For instance, while Ottawa gears up for a deep freeze and major shoveling, Edmonton recently experienced one of its warmest January days on record, and a festival in another region is adapting to an unusually warm weekend. This highlights Canada's diverse and often extreme winter climate.

For Ottawans, the focus is now on preparation. The advice is standard but critical for safety: allow extra time for travel, ensure vehicles are equipped with winter essentials, and check on vulnerable neighbours once the storm begins.
