The carrier will fly daily from Gatwick to Toronto and up to three times a week to Montreal.
Up to two flights a week will also run to Toronto from both Glasgow and Manchester over the winter.
Return fares from Gatwick start at £406 to Toronto and £407 to Montreal.
The winter flight programme offers onward connecting flights from both Canadian gateways to eight winter sun destinations in the US, Mexico and the Caribbean, including Fort Lauderdale, Dominican Republic and Cuba.
Transatlantic flights are operated by a combination of widebody Airbus A330s and single aisle A321LR aircraft.
