Naturalization as a Canadian citizen
A person who is a permanent resident may apply for Canadian citizenship by naturalization (grant) after three years resident in Canada.
The requirements in full are that the person:
is aged 18 years or over
is a permanent resident
has lived in Canada for a total of three years out of the four years preceding the application for citizenship
knows about Canada (a test is required as part of the application process, but only if the applicant is between 18 and 54 years of age)
knows the rights and responsibilities of Canadian citizenship.
Children aged under 18
The naturalization requirements for children under 18 are different to those for adults.
the child should be a permanent resident
a parent of the child should be a Canadian citizen or in the process of applying for Canadian citizenship
The residence and other requirements do not normally apply to those aged under 18.
All applicants for Canadian citizenship aged 14 or over must attend a citizenship ceremony as the final stage of their application.
