Common law refers to two people living together in a marriage-like relationship without being legally married in Ontario.

In Ontario, a common-law relationship is legally recognized when two people cohabitate continuously in a conjugal partnership. The relationship becomes legally binding after:

  • Living together for 3 years or more, or
  • Having a child together and living in a relationship of some permanence

Common-law partners in Ontario have many similar rights and obligations as married couples, particularly regarding property division, support payments, and inheritance. However, some key legal differences exist, especially concerning property rights and estate planning.
