About the London → Toronto route
London to Toronto is a proper long-haul run — just under 5,700 km and roughly 6 hours 45 minutes in the air. It's not an overnight slog, but it's not a quick hop either. You'll want a decent seat and a good playlist. Air Canada, British Airways, and Virgin Atlantic all fly it non-stop from Heathrow, which means you've got real choice on comfort and price. The route attracts a solid mix of business travellers, UK expats visiting family, and Canadians heading home after European trips. It's well-served enough that fares stay competitive most of the year.
Why travel from London to Toronto?
Toronto genuinely rewards the flight. The city's food scene alone is worth it — Kensington Market is unlike anything you'd find back home, a chaotic, brilliant mix of street food, vintage shops, and indie grocers all crammed together. If you've got family ties to Canada (and so many British people do, thanks to decades of emigration), this route is the direct line home for reunions. Business travellers move constantly between London and Toronto's financial districts — the two cities have deep commercial ties. And honestly? CN Tower at dusk, a Raptors game in winter, the Distillery District at Christmas — Toronto does atmosphere in ways that'll surprise you if you're expecting a grey corporate city.

Practical tips for LHR → YYZ
Fly in September or October for the sweet spot — summer crowds have thinned, fares drop, and the city looks genuinely stunning in autumn. Avoid March break if you hate queues. At YYZ, clear customs before you collect bags (Canada uses a kiosk system — it's quick once you get it). The UP Express train gets you downtown in 25 minutes flat and is absolutely worth it over a taxi. No visa needed for UK passport holders, just an eTA (apply online before you fly, it takes minutes). Toronto runs on Canadian dollars, not USD — easy mistake to make. And don't underestimate westbound jet lag on the way home.
