A person aged fourteen (14) or older who is granted Canadian citizenship must take the Oath of Citizenship to become a Canadian citizen. Although children under 14 years of age are welcome, they are not required to take the oath or attend a ceremony. Remember that you will need to stay on screen for the full length of the ceremony. A minor child under 14 years of age must be accompanied by the parent/guardian who submitted/signed the application on their behalf and this is also strongly recommended for minors 14-17 years of age.
