Thick fog is making for a slow morning commute across midwestern Ontario.
Environment Canada issued a fog advisory for the region early Monday morning, warning visibility may be significantly and suddenly reduced to near zero.
Drivers are being reminded to slow down and make sure their vehicle's exterior lights are switched on.
According to the national weather agency, the fog will burn off later in the morning. It will then be mostly sunny with a daytime high of 19 C, except for near Lake Huron, where the temperature will be 12 C.
