How do you join the Canadian army if you are a Jamaican citizen?

Answer 1

Become a Canadian citizen. Not trying to be crass here, it's just the option you're limited to. Unlike the UK, which allows citizens of all Commonwealth countries (and Ireland) join its military, such a policy doesn't exist with the Canadian Forces (technically, there is no Canadian Army - their entire military is a single branch).

When I was in the Canadian Army 10 years ago, there were 5 branches. I have met a few Brits and an Australian who were members of the Canadian Forces. It was easier for them to do so because they were from Commonwealth countries so background check can be done. They still had to become Canadian citizens and have completed high school with College and or university as a definate asset. No criminal record either. For non-commonwealth people, you would have to have citizenship for at least 10 years, same education, no criminal record. And a lot of luck. I suspect, with the military and the world state being what it is, it would be even harder to get in if not impossible.

Answer 2

No, you have to have Canadian citizenship I believe, so if you gain Canadian citizenship you can, but it may take awhile as they do a minimum 10 yr background check. I know a woman who lived in Russia for most of her life joined. If you're willing to gain Canadian citizenship though, you should be able to.
