这个在加拿大各省不同。比如魁北克省没有同居伴侣分后资助的要求。其他各省也不尽相同。下面是加拿大政府有关网站：

其中说：

“Under provincial law, common-law partners in Quebec are not entitled to spousal support when they separate. (In Quebec, common-law partners are usually referred to as "de facto spouses.") In other provinces and territories, a common-law partner may be eligible for spousal support from the other partner. This may depend on how long the couple lived together before they separated. For example, in some provinces and territories a common-law couple must live together for two or three years before either partner is eligible for spousal support.

Provincial and territorial rules vary across Canada. You are encouraged to check the website of your provincial or territorial Ministry of Justice or Attorney General for this information or you may contact a lawyer.”
