Flights between Heathrow and Toronto: what a delay is worth
Leaving Heathrow
£520 per passenger, UK261
Leaving Toronto
£520 per passenger, UK261
Toronto is outside the UK and EU, so coming back this only applies if a UK or EU airline operated the flight.
Either figure is payable only when the delay was within the airline's control. A technical fault, a crew shortage or a late inbound aircraft all count; genuinely extraordinary circumstances such as severe weather or an air traffic control restriction do not.
Heathrow and Toronto are 5,707 km apart (Over 3,500 km), and that distance is all that decides the amount. Which figure applies depends only on which end of the route you departed from, not which way you were travelling.
In the last 12 months, 4,383 flights operated between Heathrow and Toronto, and 1.1% were 3 or more hours late, the threshold where £520 per passenger becomes payable under UK261 (€600 under EU261).
Punctuality is up on last year: 72.3% of flights ran on time against 71.8% in the twelve months before, and the average delay fell from 19.3 to 16.5 minutes.

Your rights on this route
Every flight leaving Heathrow for Toronto is covered by UK261, whichever airline operates it. Flights the other way, leaving Toronto for Heathrow, are covered too if a UK or EU airline operated them; a flight that way on a non-UK, non-EU carrier falls outside UK261, though the Montreal Convention may still give you a claim. See the full breakdown on the 3-hour rule. Cancelled instead of delayed? Broadly the same amounts apply under different conditions. See cancelled flight compensation. Flying somewhere else in Canada?
