Canadian nationality law

Canadian nationality law details the conditions by which a person is a national of Canada. The primary law governing these regulations is the Citizenship Act, which came into force on February 15, 1977 and is applicable to all provinces and territories of Canada.

Citizenship Act
Loi sur la citoyenneté

15 February 1977

With few exceptions, almost all individuals born in the country are automatically citizens at birth. Foreign nationals may naturalize after living in Canada for at least three years while holding permanent residence and showing proficiency in the English or French language.


Canada is composed of several former British colonies whose residents were British subjects. After Confederation into a Dominion within the British Empire in 1867, Canada was granted more autonomy over time and gradually became independent from the United Kingdom. Although Canadian citizens have no longer been British subjects since 1977, they continue to hold favoured status when residing in the UK. As Commonwealth citizens, Canadians are eligible to vote in UK elections and serve in public office there.

Acquisition and loss of citizenship[edit]

Entitlement by birth, descent, or adoption[edit]

Nearly all individuals born in Canada receive Canadian citizenship by birth,[68] including those who were born in Canadian airspace, internal and territorial waters,[69] and Canadian-registered ships and aircraft.[70] The only exceptions are children born to two foreign parents with at least one who is employed by a foreign government, an employee of a foreign government, or an organization with diplomatic immunity.[71] Abandoned children found before the age of seven are assumed to have been born in Canada, unless contrary evidence is found within seven years of discovery.[72]


Children born overseas are Canadian citizens by descent if either parent is a citizen otherwise than by descent (meaning by birth in Canada or naturalization). Citizenship by descent is limited to only one generation born outside of the country,[73] other than children or grandchildren of members of the Canadian Armed Forces.[74] Adopted children are treated as if they were naturally born to the adopting parents and are subject to the same regulations regarding birthplace and descent.[75][76]
