The long wait to leave may be ending for some travellers stranded at Toronto's Pearson airport.

Air Canada announced Monday it would resume some flights grounded last Thursday by volcanic ash from Iceland.

The airline said the following flights would depart Pearson airport on Monday night: Paris (8:10 p.m. ET), Zurich (8:55) and Tel Aviv (11:55). Air Canada flights to London, Frankfurt and Munich remain cancelled but the company said it would open flights to other European destinations once the skies over those cities have been deemed safe.

There was no word Monday on whether other airlines were planning to resume their transatlantic flights.

Customers booked on Air Canada overseas flights are being told to check on the status of their flight before leaving for the airport by consulting the company's website or by calling Air Canada's automated flight information system at 1-888-422-7533.

Air Canada has revised its ticketing policy for customers booked on flights that were cancelled. Customers who make alternate travel arrangements can do so without penalty, space permitting, through the company's self-service online rebooking tool on its website.
