Toronto is under fog Sunday and drivers are warned to be careful. Environment Canada issued a fog advisory Saturday night that remained in effect Sunday morning. But it says the fog is expected to lift later on Sunday morning. Air travellers are advised to check on the status of their flights before heading to the airport because of possible delays and cancellations. Photos from across the City showed a fog that forced delays at Toronto Pearson Airport. Photos from Tom Podolec filed to CTV show a traffic-snarling blanket. Podolec reported on Twitter that flights were going around and taking more than one attempt to land.
