No, children under 18 do not need to take the Canadian citizenship test. The test is only required for applicants aged 18 to 54.
When applying for a child’s citizenship, ensure they meet the eligibility requirements, including having at least one Canadian parent or a parent applying for citizenship at the same time. You will need to submit the required documents and pay the application fee on their behalf.
While children are exempt from the test, they must still attend the Oath of Citizenship ceremony if they are 14 or older. If they are under 14, attending the ceremony is optional, but they will still receive their Certificate of Canadian Citizenship once the application is approved.
