Freezing rain is rain that freezes on contact with cold surfaces, creating a layer of ice. The live forecast above shows current freezing rain warnings and conditions across Canada. This hazard is most common in southern Ontario and the St. Lawrence Valley during winter storms.
How does freezing rain form?
Freezing rain develops when snow falls through a warm layer of air, melts into rain, then hits a freezing layer near the ground. The raindrops become supercooled and freeze instantly on roads, trees, and power lines. Check the 10-day forecast to see if a warm front is approaching your area.
What are the main risks?
Ice accumulation of just 2–5 millimetres can make sidewalks and roads extremely slippery. Heavier ice—over 10 mm—can snap tree branches and bring down power lines. Ottawa weather and Toronto weather pages include current warnings for these events. For a broader view, consult the Canada weather hub or a Environment Canada weather map.
How is freezing rain different from sleet?
Sleet is frozen rain that bounces on impact; freezing rain stays liquid until it hits a surface. Sleet piles up like snow, while freezing rain creates a smooth, dangerous glaze. Both require temperatures near 0°C.
Should I drive during a freezing rain warning?
No. Even a thin layer of ice makes roads treacherous. If you must travel, reduce speed, avoid sudden braking, and check The Weather Network for live updates. Many Ontario weather warnings today include travel advisories.
How can I protect my home?
Keep gutters clear to prevent ice dams. Have salt or sand ready for walkways. If ice builds up on power lines, report it to your utility and stay at least 10 metres away. For health tips during power outages, see Health Canada.
