The guidelines state that a person needs to reside in Canada 1095 days out of a four year period previous to applying for citizenship. Up to now, these residency regulations have not been tightly defined. The government has been looking at amending the Citizenship Act for years, but no new act has made its way through Parliament that deals with a change in residency. It is, therefore, possible that even if you do not have 1095 days of residency, you could still apply and become a citizen of Canada, although it is not as automatic.
