What Is Causing Flight Cancellations Across Canada Today?

Flights to and from Toronto are being cancelled or delayed today, July 2, primarily due to a severe and prolonged extreme heat wave blanketing the region. The intense heat and high humidity have reduced air quality, prompting Environment Canada to issue an orange heat warning and creating challenging operational conditions for airlines and ground crews at both Toronto Pearson (YYZ) and Billy Bishop (YTZ). As Canada’s busiest aviation gateway, disruption in Toronto has also contributed to delays and cancellations spreading through airline networks serving cities including Montreal, Ottawa, Vancouver, Halifax, Quebec City, Edmonton, and Victoria.
