加拿大護照想用回本姓..因現隨夫姓氏

Sorry for the passing away of your spouse.

I suggest you to bring along the original copies of your marriage certificate, the death certificate of your spouse, the existing documents/cards, and go to the respective Government Departments to apply for the change of new documents.

Or you might spend some monety to approach a lawyer and do these process under his/her advices.

I have tried my best to help you.
