ok, can an American move to Canadaicon and legally own / purchase firearms? and once said American moves to Canada, does he lose his citizenship in the US?

reason I ask, i want to move to Canada for a few or more years but not permanently and join the northern rangers. I contacted the rangers and they said I can legally join as long as I am a Canadian citizen.

Also, a few of my buddies who have friends / family say that Canada still has a workforce unlike the US. there be work up north fellers!!!
