It was expected to be a foggy, slick commute Monday morning for people across the London region.
Environment Canada issued a fog advisory for London, Middlesex County, Oxford County and Elgin County just after 7 a.m.
Freezing fog settled into the area and is leading to near zero visibility in spots and causing some roads to become slippery, the weather agency said in a statement.
Drivers were advised to slow down, watch for tail lights in front of them, and be prepared to stop.
The advisory was lifted later in the morning.
