I have dual citizenship in US and Canada. I have a citizenship card that was issued when I was infant. I would like to apply for a Canadian passport but I am really worried about sending this document to Canada as it is the only document I have that shows citizenship. My gut says to hold onto it and use my US passport if we decide to go to Canada. I know about the strike going on, so if I apply, I will send it through a different shipping company. Also wondering if it would be better to go to Canada and apply in person. I appreciate any insight, thank you!
