Ottawa's latest bout of freezing rain has come and gone, with Environment and Climate Change Canada officially lifting the weather warning after a period of icy precipitation coated roads, sidewalks, and surfaces across the city.
What Happened
Ottawa was hit with freezing rain that prompted an official weather warning, with Carleton University among the local institutions that flagged the alert for students and staff navigating campus. Freezing rain — which forms when supercooled water droplets freeze on contact with surfaces — creates some of the most treacherous conditions of the winter season, turning every step and every commute into a potential hazard.
The warning has since been lifted, signalling that the precipitation has moved out of the region and temperatures have stabilized enough to reduce the icing risk.
Still Slippery Out There
Just because the warning is over doesn't mean the danger is. Residual ice on untreated surfaces can linger well after freezing rain stops, especially in shaded areas, side streets, and pedestrian pathways that haven't been salted or sanded. Ottawa residents should continue to:
- Watch their step on sidewalks, parking lots, and stairs
- Allow extra time when driving, as black ice can persist even when roads appear clear
- Check on neighbours, especially elderly residents who may need help with icy walkways
- Wear appropriate footwear — ice cleats or boots with aggressive grip make a real difference
Freezing Rain Season in Ottawa
Ottawa's shoulder seasons — late fall and early spring — are prime time for freezing rain events. The city sits in a geography that makes it particularly susceptible to the temperature inversions that cause this type of precipitation. Unlike a blizzard, freezing rain arrives quietly and leaves behind a thin, deceptively dangerous glaze.
The City of Ottawa's roads and public works crews typically respond quickly to freezing rain events, deploying salt trucks and sand to major roads and intersections. However, residential streets and bike paths are often slower to be treated, so extra vigilance in those areas is always warranted.
Stay Informed
For the latest road conditions, residents can check the City of Ottawa's winter road maintenance map online. OC Transpo may also adjust schedules or routes during severe icing events, so checking the transit app before heading out is always a good idea during icy weather.
Environment Canada's weather alerts for the Ottawa-Gatineau region are updated in real time at weather.gc.ca — bookmarking that page during the spring transition season is a smart move.
Stay safe out there, Ottawa. Spring is close, but it's not quite done with us yet.
