Flights from Toronto to London
The Toronto–London Heathrow corridor is one of the busiest transatlantic connections in the North Atlantic network, covering roughly 5,700 kilometres with a typical westbound block time around seven hours and an eastbound flight of closer to six and a half hours thanks to the jet stream. Air Canada is the dominant carrier and operates the route from Toronto Pearson's Terminal 1, typically deploying Boeing 787 Dreamliners and occasionally 777s; American, Lufthansa, and Iberia also serve the pairing, often as extensions of their own hub networks. A practical note worth flagging: most transatlantic arrivals into Heathrow land at Terminal 2 or Terminal 5, so confirm your terminal before booking an onward train or taxi, as the transfer between terminals eats meaningful time. On fares, shoulder seasons in late January through March and again in October tend to offer the lowest economy pricing, while business-class award availability on Air Canada's Aeroplan program is often strongest on midweek departures.
