London to Montréal (LHR–YHU) — Airlines, Schedules & Connections

British passport holders need an Electronic Travel Authorization (eTA) to fly to Canada. The eTA costs CAD 7 (about $5), is processed in minutes (most approved instantly), and is valid for 5 years or until passport expiry, whichever comes first. Apply at canada.ca/eta. Each entry allows stays of up to 6 months. If arriving by land or sea from the US, no eTA is required.

Passport must be valid for the duration of the stay. Border officers may ask for proof of onward travel, accommodation, sufficient funds, and ties to the UK. The 6-month stay limit is per entry, and there is no hard annual cap, but frequent extended stays will draw scrutiny. For longer stays, apply for a visitor record extension inside Canada (CAD 100) before the 6 months expire.

Direct flights from London Heathrow to Toronto run about 7 hours 40 minutes, to Vancouver about 9 hours 20 minutes. Air Canada, British Airways, and WestJet operate nonstop service. Canada uses the Canadian dollar (CAD), trading at roughly 1.36 CAD per $1. No vaccination requirements for UK arrivals. Canada uses the metric system but road speeds are in km/h. A UK driving license is valid for short-term visits in all provinces.
