Divorce in Canada is governed primarily by the federal Divorce Act, which applies uniformly in every Canadian province and territory. The Divorce Act sets the grounds for divorce, defines parenting arrangements, and establishes the framework for child and spousal support. Provincial family law governs parenting and support for unmarried couples, property division, separation agreements, and court procedures.
Under Canadian divorce law, the only ground most married couples need to establish is marriage breakdown. In practice, over 97% of Canadian divorces use the no-fault ground of living separate and apart for one year, a straightforward test that applies equally across every Canadian province.
The Civil Marriage Act and the Divorce Act together form the cornerstone of Canadian marriage and divorce legislation, and neither requires proof of fault, adultery, or wrongdoing to proceed. Adultery and physical or mental cruelty remain available as grounds, but they are rarely used because they add cost and complexity without improving the outcome.
