Cheap Flights from Toronto to London — $235

Toronto is served mainly by Toronto Pearson International (YYZ) and Billy Bishop Toronto City Airport (YTZ), with several smaller regional fields nearby. Pearson functions as the city’s primary international hub, typically handling most long-haul and legacy-carrier flights (Air Canada, WestJet and many global carriers) and can feel busier and more full-service. It sits about 22 km northwest of downtown; travel options include the UP Express train (roughly 25–30 minutes, moderate fares), GO Transit and taxis or rideshares (30–45 minutes depending on traffic, higher cost). Billy Bishop, adjacent to the waterfront, primarily hosts regional and some transborder carriers and is often seen as more convenient for downtown access (a short ferry or pedestrian tunnel and under 15 minutes to the core). Pros: Pearson’s broad route network and amenities; Billy Bishop’s quick city access. Cons: Pearson can involve longer transfer times and variable traffic; Billy Bishop offers fewer long-haul options and can be pricier per seat for short-haul convenience.

London is served by several distinct airports, each suited to different traveler needs. Heathrow (LHR) is the main international hub, favored by full-service carriers and alliances for long-haul and premium connections; it can be pricier than other options and sits about 15–25 km west of central London. The Heathrow Express links to Paddington in roughly 15–20 minutes (higher fares), while the Elizabeth Line, Piccadilly Line, and frequent buses or taxis offer 30–60 minute journeys at lower cost. Gatwick (LGW) operates as a major south-of-London international and leisure gateway with a mix of full-service and low-cost airlines; it’s around 40–50 km from central London and reachable by 30–40 minute Gatwick Express or 30–60 minute trains and coaches, with fares spanning budget to mid-range. Stansted (STN) and Luton (LTN) are typically budget-carrier dominated and positioned further out—about 60–70 km north/northeast—making bus or coach transfers (45–90 minutes) and rail-plus-shuttle combos common low-cost options. London City (LCY) serves business travelers as a compact, centrally located airport in the Docklands, roughly 10 km east of the centre, with quick DLR and bus links (15–25 minutes) but limited long-haul services and typically higher fares. Each airport offers trade-offs between convenience, comfort and ticket cost: Heathrow and London City can be more comfortable and quicker for central access, while Gatwick, Stansted and Luton often offer cheaper flights at the expense of longer transfers and simpler facilities.

In different months, ticket prices from Toronto to London vary: minimum — $253 (June 2026), maximum — $305 (September 2026). Typically, the flight costs $287–$295.
