To become a Canadian citizen, you must:
be 18 years of age or older;
be a permanent resident of Canada;
have lived in Canada for at least three of the four years before applying;
be able to communicate in either English or French;
know about Canada; and
know about the rights and responsibilities of citizenship.
Adults must have lived in Canada for at least three years (1,095 days) out of the four years preceding the application. Please note that you cannot meet the residence requirements for citizenship without a minimum of 2 years as a permanent resident. Time spent in Canada before becoming a permanent resident may be counted toward becoming a Canadian citizen if it falls within the four-year period. To find out if you meet the residence requirements to become a Canadian citizen, you can use the residence calculator.
A child (under 18 years of age) must be a permanent resident of Canada to apply for Canadian citizenship. To apply on behalf of your child, you must either:
already be a citizen; or
apply for citizenship at the same time.
Children do not need to have lived in Canada for three years before applying.
avid_2005，我是有移民身份，刚在加生了宝宝回到中国，那我的宝宝在满18岁后还须向加国政府申报吗？如必须申报，那在什么期限内申报？如果因为我及老公均因未能达到5年内住满2年的要求而丧失永久居民的身份，且宝宝在出生后从未回过加国，是否会影响我宝宝的国籍？麻烦了。
