Legal Definition of Marriage Under Canadian and Ontario Law

In Canada, marriage is governed federally by the Civil Marriage Act and, for divorce, by the Divorce Act. Both laws define marriage as a legal union between two people. Ontario family law, including the Family Law Act, is built on this same foundation.

From a legal perspective:

  • A marriage can only exist between two spouses
  • Only those two spouses acquire automatic rights and obligations related to property division, spousal support, and divorce
  • Courts do not assess or validate alternative relationship structures when determining marital status
