Can my US born son live in Canada with his Canadian Born Parents

[Olychamp]

Hi,

Just wondering if my US son can live in Canada with my wife and I (both Canadian born) with just his US birth certificate? He does have a Naturalization card, but we have lost it. We really don't want to have to replace it if it's not necessary. Thanks!

You will need it at some point to prove that he is a citizen or he may need it himself. Maybe you will not need it today or tomorrow or next week but you should replace it.
