My father is a Canadian citizen by birth (born in Canada), my mother and I are both American citizens. We all live in the United States (my father as a green-card permanent resident -- he has been an ex-pat my whole life). I am 26 years old.
Am I eligible to claim Canadian citizenship?
You probably are a Canadian citizen, in which case, yes.
The page on citizenship rules suggests that you have been a Canadian citizen from birth because your father is a Canadian citizen born in Canada.
Some countries will adjudicate your claim to citizenship as part of an initial passport application, but Canada seems to want you to apply for a certificate of citizenship first, which costs $75 and takes about five months (Canadian dollars).
