Environment Canada issued a fog advisory for Tillsonburg, Ontario, at 6:21 AM on February 14, 2026. The alert warns of near-zero visibility that could make morning travel hazardous across Woodstock and Oxford County.
The weather agency has labeled this a “Yellow” advisory, which means there is a moderate risk of localized disruptions and a high level of certainty in the forecast. Drivers are encouraged to slow down, watch for tail lights ahead, and be prepared to stop suddenly if visibility drops.
For those traveling on Highway 19 or Highway 3, officials recommend using full headlights rather than just daytime running lights. This ensures that rear tail lights are on, making vehicles easier for others to see in the thick fog.
Dense morning fog often impacts local school bus schedules managed by the Southwestern Ontario Student Transportation Services. Under current policies, extremely low visibility typically results in morning bus routes being cancelled entirely instead of just being delayed.
According to the Government of Canada, this colour-coded system is designed to help residents quickly understand weather risks. The fog is expected to clear and the advisory should be lifted later this morning.
