Air Canada (AC.TO) after trade Tuesday issued an update on its operations after recent severe winter storms in Eastern Canada and the Monday crash of a plane operated by a U.S. rival at its Toronto Pearson global hub that caused injuries but no fatalities.

Eastern Canada was hit by a snow storm over the long weekend holiday, while a Delta Air Lines (DAL) plane crashed Monday afternoon when landing at Toronto's main airport, flipping over and leading to extensive delays with other flights over the last 24 hours and more.

Air Canada has cancelled approximately 1,290 flights over the past six days due to the storm and the accident. Fortunately, none of the Delta passengers were killed, but 21 were injured and taken to hospital.

"We are currently restoring our service, adding extra flights and capacity where possible. However, the necessary and ongoing reductions in the number of take-offs and landings permitted at our global hub in Toronto is slowing the speed of recovery. We anticipate it may take several more days, depending on the weather, to return to fully normal operations. We appreciate our customers' understanding during this time," Air Canada said in a statement.

Air Canada shares closed down $0.27 to $17.48 on the Toronto Stock Exchange.
