魁北克有common law的，不過，無論common law多少年都不等同於結婚配偶

隻有在有關職業援助、收入稅務、省退休金計劃，和職業補償的方麵，commen law才享有夫妻一樣的權利和義務。其他方麵沒有（“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”）
