Do I need a visa to visit Canada from the UK ?

No visa required If you are UK citizen.

No you don't need a visa if you're a citizen of the UK.... you need a valid passport and a government issued photo ID such as a driver's license

I dont think that you need a visa depending on how long you plan to stay in the country. You will need a passport though.

no - as long as it's just for a holiday. If you want to work you will need a visa - i got a domestic one when i went out to be a nanny

It's the most fantastic country - you will love it!

no just your passport

It's not maditory but if you have a Mastercard or American Express that will do as well.

depends on what passport you are holding. As a British national, no.

NO !!!
Canada is a independant common wealth country as well
