Lowest fares from Toronto to London
What to know before you book Toronto to London
Toronto to London is one of the busiest routes out of Pearson: Air Canada, British Airways and Virgin Atlantic fly nonstop to Heathrow, and Air Transat flies to Gatwick. The overnight flight takes about seven hours, so you land in the morning UK time.
Heathrow or Gatwick?
Heathrow (LHR) is on the Elizabeth line and the Piccadilly line, and the Heathrow Express reaches Paddington in about 15 minutes. Gatwick (LGW) is south of the city, about 30 minutes to Victoria on the Gatwick Express. Pick the airport that fits where you're staying, not just the cheaper fare: a cross-London transfer can eat the saving.
Get your UK ETA first
Canadians need a UK Electronic Travel Authorisation (ETA) before boarding. It costs £20 since April 8, 2026, and you apply in the official UK ETA app or on GOV.UK. Most decisions are quick, but apply a few days ahead, and only through the official government site.
Using London as a gateway
Fares from Toronto to London are often lower than to other European cities, and trains and short flights connect onward. If you book the next leg separately, leave a long gap: if your first flight is late, the second airline doesn't have to wait or rebook you.
