My daughter’s father comes from Canadian lineage. His mother is American, but his biological grandparents are Canadian. He was adopted and his last name changed at the age of four, by his stepfather when his mother married. My daughter would like to apply for Canadian citizenship, but not sure how to navigate around this. Her father is no longer in the picture nor would he be willing to help her in anyway and it’s doubtful that he has any of the paperwork surrounding his adoption (its been more than 50 years).

Is my daughter out of luck in this case?
