Flights to Toronto will start from May 1 and will be BA’s first route to Canada from Gatwick, with three flights per week.
Las Vegas will be returning with three flights per week from Gatwick, starting on March 27, following "high demand" for flights operating from Heathrow.
The news follows the recent introduction of new long-haul routes to Oakland and Fort Lauderdale in the US.
The additional two destinations take the number of new routes introduced at Gatwick in 2017 to six and the total number of routes flying from the airport to 71.
Sean Doyle, director of networks and alliances at British Airways, said: “Gatwick has always offered a great range of long-haul destinations, but adding Toronto and Las Vegas to the summer schedule will take the number of transatlantic routes to 21, making Canada, the US and the Caribbean more accessible than ever before.
“It’s particularly exciting to be adding Canada to the list of places our customers will be able to explore from Gatwick, and we look forward to welcoming our Canadian customers to London.”
Summer 2018 fares on Toronto flights will start from £453 return and fares to Las Vegas from Gatwick will start from £699 return, including taxes and charges.
