RE:RE:AC flight cancellations out of Torontohttps://flightaware.com/live/cancelled/yesterday/yyz
Yesterday, About 4% flights canclled out of Toronto. Similar numbers out of Van and Montreal.
A quick look at cancelled flights (in last 2 days) out of Toronto shows that many of the flights were at multi flight routes, leading to flight consolidation.
