Toronto To London: A Straightforward Transatlantic Route
What to expect flying from Toronto to London, including flight length, airport flow, and arrival routines.

Toronto to London is one of the more approachable transatlantic routes on the map, with a flight time of around 7 hours eastbound, similar to the New York to London route but starting a little further north and west.
It is also a route many travelers use to connect onward across Europe, since London serves as a well connected gateway for continuing trips.
Flight Timing And Direction
Eastbound flights from Toronto commonly depart in the evening and land in London the next morning, a familiar overnight pattern for this part of the world. The five hour time difference means you lose sleep hours quickly, so resting on the plane matters more than it might seem beforehand.
Westbound back to Toronto, flights tend to depart London around midday and land back in Toronto the same afternoon, which is a considerably easier direction to adjust to.
Airport Considerations In Toronto
Toronto's main international terminal is well organized, though security and check in lines can lengthen quickly during the evening departure rush that overlaps with several transatlantic flights leaving around similar times. Winter weather can occasionally slow ground operations, so build a little extra time into your plans during colder months.
If you are flying in from another Canadian city to connect in Toronto, treat that domestic leg with the same caution as an international connection, since a delay can cascade quickly.
Airport Considerations In London
On arrival in London, expect the walk from gate to immigration to take a while, and expect lines to vary depending on how many long haul flights land around the same time as yours. Electronic passport gates have sped things up for many travelers, but not everyone qualifies to use them.

Once through arrivals, train and taxi options into the city are plentiful, though morning crowds mean a taxi may be a calmer option if you are traveling with a lot of luggage or feel particularly tired.
Onward Connections From London
If your trip continues beyond London, give yourself a wider buffer than the minimum connection time suggests, especially after an overnight arrival when queues at immigration and security can be unpredictable. It's a route where a little extra patience at the planning stage saves stress later.
Making The Most Of Arrival Day
Because you land into a full London day after an overnight flight, plan something light for the first few hours, a walk, a coffee, maybe an early check in attempt, before committing to anything more demanding.
- Rest on the eastbound leg whenever possible, since the arrival is a full working morning.
- Allow extra time for evening security lines out of Toronto.
- Consider a taxi over public transport on arrival if you are carrying heavy luggage.
- Build a wider buffer for any onward connection out of London.
Documents, Currency, And Local Orientation
Canadian passport holders do not need a visa for short visits to the United Kingdom, but it is worth double checking current entry rules before you fly, since requirements for pre-travel authorization have shifted in recent years. Bringing a printed copy of your return flight details or itinerary can speed up questions at the border if an officer asks about your plans.
The UK uses pounds rather than the Canadian dollar, and contactless card payment is widely accepted on buses, the Underground, and in most shops, so carrying a lot of cash is rarely necessary. A UK-compatible plug adapter is worth packing, since Canadian and British sockets are not the same shape despite both using similar voltage in some devices.

- Confirm current UK entry requirements for Canadian travelers before departure.
- Pack a UK plug adapter rather than assuming Canadian chargers will fit.
- Rely on contactless card payment for buses and the Underground instead of cash.
