75% fewer flights landed as scheduled at Pearson Airport in Mississauga, Ontario due to heavy fog

About 75 per cent fewer flights than usual landed as scheduled at Pearson Airport in Mississauga on Thursday morning due to heavy fog that set in across the region.

While officials at Pearson said conditions had improved as of late this afternoon and that “regular operations have resumed,” numerous scheduled arrivals were impacted earlier in the day.

“Fog continues to affect operations at Toronto Pearson today. Nav Canada adjusted the morning hourly arrival rate to roughly a quarter of what we see on a typical day and the Federal Aviation Administration (in the U.S.) has relayed this to flights leaving the United States for (Pearson),” airport officials said in a social media post late Thursday morning. “Seven flights have been diverted from Pearson and others will be arriving late, which will affect some connecting passengers.”

Also earlier on Thursday, airport officials said via X (formerly Twitter) that Nav Canada was “managing the flow of aircraft” at Pearson during the morning hours due to the heavy fog, which could create safety concerns for both arriving and departing flights.

A fog advisory from Environment Canada issued Thursday morning warned that “near zero visibility” conditions were expected in some areas, including Pearson.

Late this afternoon, airport officials reported that the foggy conditions had cleared and it “looks like pleasant skies for the rest of the day…regular operations have resumed at Toronto Pearson.”
