I was born in Ontario, Canada in 1950 to Canadian born parents. Moved to US in 1962 and became a US citizen in 1972. At that time, Canada did not recognize dual citizenship. In 2009, an Amendment to the Canada Citizen Act stated you were a Canadian citizen if “you were born or naturalized in Canada on or after January 1, 1947 and lost your Canadian citizenship.” Not sure if 'lost' is the same as 'relinquished' or 'revoked' (don't recall signing any documents for Canada revoking or relinquishing my citizenship at the time I became a US citizen) and whether I qualify now to obtain either a Canadian passport or citizenship certificate. Also, do I have to actually establish residency in Canada in order to regain my citizenship? I don't want to start the application process with it's nonrefundable fees unless I know that 1) I qualify for citizenship, 2) whether it's better to obtain a passport or a citizenship certificate, and 3) I don't have to move to Canada to regain citizenship. The Canadian Immigration website and the Passport website are not clear on the requirements to regain my Citizenship. Any insight is appreciated along with what specific documents are required.
