Canadian by Descent with an adopted parent.
I am receiving mixed messages regarding my eligibility of Canadian Citizenship by descent. My Gen 0 is my great-great-grandmother, born in Quebec. My grandfather adopted my mother as an infant. It is my understanding my mother is eligible for Canadian Citizenship through CIT 0010. We're currently battling with the state to locate a Certified Adoption Decree, which is turning out to be a very difficult process, even though we know the identities of her birth parents.
Where I come in is that I plan on applying for proof of citizenship using CIT 0001, as I've already sourced all of the required documentation to provide the line of descent to my grandfather. I was told by a Canadian immigration attorney that I am eligible, but my mother must submit her application using form CIT 0010, and that we should include the applications in the same mailer in separate envelopes. He said that I am not applying to be granted citizenship through my mother, but as an individual by descent, and I should include a letter of explanation that my mother was adopted.
u/tabbysthreads appears to have had success with her children being approved using this process. So I am very confused by what I hear on this subreddit with people being told they are ineligible, where as my conversation with a Canadian immigration attorney & u/tabbysthreads experience seem to say otherwise. In short, I'm going to go ahead and apply once we get the adoption decree and I'll let y'all know what happens. The worst thing that could happen is I'm rejected and am out of $55.
