On the morning of February 17, 2026, Environment Canada issued a weather alert for Aurora, Ontario, warning residents of near-zero visibility caused by dense fog. The advisory, which also covers Newmarket and Georgina, comes as humidity levels reached 100 per cent and temperatures stayed just above freezing at 0.7°C.
Commuters are being told to prepare for sudden drops in visibility that could make morning drives and school drop-offs hazardous. Officials suggest that drivers use their full headlights, reduce their speed, and keep extra space between vehicles until the fog clears later this morning.
The fog arrives while the York Region District School Board is testing a new way to handle weather delays. As of January 5, 2026, Student Transportation Services of York Region has started using two separate zones to decide if school buses should be cancelled during localized weather events.
While the fog is expected to lift, more difficult weather is on the way for the middle of the week. A winter storm watch has been issued for Wednesday, February 18, 2026, with 10 to 15 centimetres of snow and ice pellets expected to hit the region.
