Visitors travelling to Canada by air are now expected to get an electronic travel authorisation (eTA) to enter Canada. For more information about the eTA system, and to apply online, visit the official Canadian government website. See Entry requirements
If you’re visiting Canada you’ll need an eTA to board your flight unless you’re otherwise exempted (for example, if you have a valid Canadian visa or a permanent resident card). If you have British-Canadian dual nationality you won’t be able to apply for an eTA and you’ll need to present a valid Canadian passport to board your flight to Canada.
Terrorists are likely to try to carry out attacks in Canada. See Terrorism
Around 724,000 British nationals visit Canada each year. Most visits are trouble free.
If you’re abroad and you need emergency help from the UK government, contact the nearest British embassy, consulate or high commission.
Take out comprehensive travel and medical insurance before you travel.
