The airline last launched flights to Toronto in 2001, but these were halted by the 9/11 attacks. It also briefly operated to Vancouver between 2012 and 2014.
Virgin has now resumed the Toronto route with the added impetus of attracting passengers wanting to connect to and from India via London, as well as those from the UK wanting to visit Canada itself.
Meanwhile the airline is reducing the number of flights from Heathrow to Seattle from daily to four a week next winter, with the route also being operated by major shareholder Delta, which has a hub at the Pacific coast destination.
