Can a common-law partner claim spousal support in Ontario?
Yes, once a couple meets the qualifying threshold under the Family Law Act — three continuous years of cohabitation, or a relationship of some permanence with a child together — either partner can apply for spousal support. The same factors that apply to married spouses govern the claim: the length of the relationship, the roles each partner played, financial dependency, and any economic disadvantage suffered as a result of the relationship.
Judges use the Spousal Support Advisory Guidelines (a federal framework) as a reference tool when calculating ranges for amount and duration. While these guidelines are not binding, Ontario courts rely on them heavily. The length of cohabitation typically affects the duration of any support awarded.
If the relationship does not yet meet the statutory threshold, no support right exists under the Family Law Act, though a claim might theoretically arise in contract or equity in unusual circumstances. Getting clarity on your eligibility early — ideally before or immediately at separation — is important because limitation periods can affect your ability to claim.
