魁北克有common law的，不过，无论common law多少年都不等同于结婚配偶

只有在有关职业援助、收入税务、省退休金计划，和职业补偿的方面，commen law才享有夫妻一样的权利和义务。其他方面没有（“Québec lawmakers, respecting the freedom of choice of couples living in a de facto union, have deliberately chosen not to extend to de facto couples the same rights and responsibilities that married or civil union couples have under the Civil Code of Québec, regardless of the number of years of cohabitation”）
