01 · Overview
Ontario’s classic hop to Heathrow
Most Toronto travellers aim for Heathrow because nonstops, lounge access and Piccadilly / Elizabeth line links into central London are straightforward. Gatwick, City and Stansted can appear in one-stop or ULCC-adjacent searches — only switch if total door-to-door time wins.
Budget in CAD. Summer leisure, Christmas and half-term UK school weeks firm fares. Late January–March (outside February break) and late October–November shoulders often soften both flights and Zone 1 hotels.
Compare Air Canada and British Airways in the Travelpayouts widget first, then weigh bag/seat bundles carefully on basic economy.

Heathrow vs other London airports
This page focuses on London Heathrow (LHR) as the primary YYZ destination. Terminal transfers, Heathrow Express and the Elizabeth line shape your arrival plan.
Gatwick can work for southern England itineraries; London City suits docklands business but rarely beats LHR on nonstop convenience from Toronto.
Arrive sleep-deprived: build a soft first afternoon — hotel check-in or luggage storage — before ambitious West End evenings.
03 · Timing
Shoulder months vs summer Europe
July–August and Christmas are premium. Shoulder spring and autumn often deliver the best CAD balance for city breaks.
UK bank holiday weekends firm Zone 1 hotels even when flights look soft — price lodging early.
Red-eye westbounds home can feel long; protect connection buffers if you are not on a true nonstop return.

Who flies YYZ–LHR?
Air Canada and British Airways anchor the nonstop product. Partner one-stops via Montreal, European hubs or the US Mid-Atlantic rarely beat schedule reliability for a week in London.
Premium economy can be worth the CAD uplift on overnight eastbounds if you need to work day one.
Watch fuel surcharges and award charts if redeeming Aeroplan or Avios — cash CAD in the widget is the sanity check.
