not become an alien; a British subject possessing Canadian domicile; and a person naturalized under the laws of Canada who had not subsequently become an alien or lost Canadian domicile. Aliens, as well as all other British subjects, who wished to immigrate to Canada required permission to land. "Domicile" was declared to have been acquired by a person having his domicile in Canada for three years after having been landed therein, excluding any time spent in "any penitentiary, jail, reformatory, prison, or asylum for the insane in Canada." Although the terms "Canadian citizen" and indeed "Canadian citizenship" were used in this Act, they did not create the legal status of Canadian citizen in a nationality sense. People who had the status of "Canadian citizen" were merely free from immigration controls. In 1911, at the Imperial Conference a decision was made to draft a common nationality code defining British nationals for use across the empire.

The uniform law, which went into effect on 1 January 1915, required a married woman to derive her nationality from her spouse, meaning if he was British, she was also, and if he was foreign, so was she. It stipulated that upon loss of nationality of a husband, a wife could declare that she wished to remain British and provided that if a marriage had terminated, through death or divorce, a British-born national who had lost her status through marriage could reacquire British nationality through naturalisation without meeting a residency requirement. The statute reiterated common law provisions for natural-born persons born within the realm on or after the effective date. By using the word person, the statute nullified legitimacy requirements for jus soli nationals. For those born abroad on or after the effective date, legitimacy was still required, and could only be derived by a child from a British father (one generation), who was natural-born or naturalised. Naturalisations required five years residence or service to the crown. By 1918, the rise of women's suffrage motivated new federal interest in the question of women's nationality, but the country's legislative ability to change its nationality laws was limited by the common code for Dominions of Britain that required legal changes to be
