Canadian nationality law details the conditions in which a person is a national of Canada. 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. As Commonwealth citizens, Canadian citizens have favoured status when residing in the United Kingdom; those living in the U.K. are eligible to vote and serve in public office or non-reserved government positions.
