"Dense fog reducing visibility to 200 metres or less is expected until mid morning," says EC in the statement.

"If traveling, be prepared for areas of near zero visibility," EC adds.

The dense fog is not only impacting travel on the roads. Porter Airlines warned of potential delays and cancellations due to the fog and is advising those with air travel plans to check their flight status before heading to the airport.

Pearson airport says operations are running normally.

The fog is expected to lift late morning, but another shot of heavy rain and thunderstorms are possible through the afternoon and evening hours.
