依照移民法对枫叶卡在5年内满2年的规定如下：
(a) a permanent resident complies with the residency obligation with respect to a five-year period if, on each of a total of at least 730 days in that five-year period, they are
(i) physically present in Canada,
(ii) outside Canada accompanying a Canadian citizen who is their spouse or common-law partner or, in the case of a child, their parent,
(iii) outside Canada employed on a full-time basis by a Canadian business or in the federal public administration or the public service of a province,
(iv) outside Canada accompanying a permanent resident who is their spouse or common-law partner or, in the case of a child, their parent and who is employed on a full-time basis by a Canadian business or in the federal public administration or the public service of a province, or
(v) referred to in regulations providing for other means of compliance;
意思是以上5种情形都可以算做是5年内住满2年而进行换发新的枫叶卡，其中第2项就是你陪伴公民配偶在海外（加拿大以外的地区）的日子也能算在730天里面，既然还是要算730天，所以我认为你配偶如果在第5年末才拿到公民，然后回到中国和你一起生活，这样你已经来不及在这个5年内达到730天的要求了，既然这5年无法满足居住730天的条件，就没办法换新的发枫叶卡
