Flight cancellations & delays have been plaguing Pearson on Sunday after snowfall Saturday.

Over 100 Sunday flights between Toronto, Quebec & the eastern US impacted after a similar number of cancellations Saturday.

The Greater Toronto Airports Authority blames Saturday's snow & a storm hitting northeastern states for the scrapped or delayed flights.

The airport hopes to have the backlog cleared by Sunday night.

If you're flying out of Pearson or expecting someone flying in, check the status of your flight before heading out to the airport.
