Is it possible you’re a Canadian citizen? Citizenship and Immigration Canada says:
A new law amending the Citizenship Act will come into effect on April 17, 2009. The new law will give Canadian citizenship to certain people who lost it and to others who will be recognized as citizens for the first time. It will also protect the value of citizenship by limiting citizenship by descent to one generation outside Canada.
Look for the questionnaire to help you determine if you are able to claim Canadian citizenship.
