Cheap flights from London to Toronto

December is the cheapest month on this route, and the dated fares on this page let you compare it with the rest of the year. Winter is the softer season for transatlantic travel, though the run-up to Christmas and the days around New Year fill up quickly in both directions. Late spring and summer are the busiest, when school holidays in Canada and the UK overlap. Midweek departures, especially Tuesday and Wednesday, usually cost less than Friday or Sunday flights. Book well ahead for summer and the Christmas peak; for quiet weeks in autumn and late winter you can often leave it later.

The airline mix on this route is wide. Full-service carriers such as Lufthansa, Swiss, Brussels Airlines, TAP Portugal and Icelandair sell connections through their own hubs, and a checked bag and meals are usually part of the fare. Edelweiss Air and Air Baltic work in a similar way on their networks, and Portug appears in the results too. WestJet and Air Transat are the Canadian carriers you will see most on the non-stop side, and they sell fares in tiers, so a hand-baggage-only ticket costs less than one with a checked bag and a seat choice. On connecting itineraries, check whether the whole trip sits on one ticket, because that decides who rebooks you when a flight is delayed.

Most long-haul arrivals land at Pearson International, west of the city, and you reach the centre by train or bus, with taxis and ride shares outside the terminals. Billy Bishop City A/P sits on the island by the harbour, close to downtown, and it handles regional traffic rather than the transatlantic flights. If your ticket says Toronto but not which airport, check it before you book ground transport, because the two are on opposite sides of the city. At Pearson, allow time for immigration, and keep your onward booking handy if you are connecting to another Canadian city.

Country facts: Wikidata

• Check which London airport you leave from, since Heathrow, Gatwick, Stansted, Luton and London City sit far apart.
• On WestJet and Air Transat fares, confirm whether a checked bag is included or sold as an extra.
• If you build the trip from two separate tickets, a missed connection is yours to fix, not the airline's.
• Carry a valid passport and check Canada's entry rules, including any visa or electronic travel authorisation, well before you fly.
• Compare December fares with the summer months, because the cheapest month on this route is not when most people travel.
• For a December trip, book ahead of the Christmas rush, when seats on both direct and connecting options go quickly.
