We weren't married — just living together. Can my partner claim spousal support when we separate?
Yes — under specific conditions. In Ontario, unmarried cohabiting partners (common-law partners) can claim spousal support if they meet either: (1) continuous cohabitation of 3 years or more, or (2) cohabitation of some permanence with a child of the relationship. The calculation rules, three entitlement bases, and SSAG formulas all mirror married couples. Critical difference: common-law partners do NOT have automatic property division rights (no Net Family Property equalization). Common-law claimants must bring their support claim within 2 years of separation. For entitlement basics, see who is entitled to spousal support; for amount and duration, read how amount and duration are determined; for the broader common-law vs marriage comparison, see common-law vs divorce in Ontario.
Key Points
Yes — and this is one of the biggest blind spots for clients from China, who often assume 'no marriage certificate = nothing to settle.' That assumption costs real money: one partner forfeits years of legitimate spousal support, while the other faces unexpected payment obligations they were never warned about.
Under section 29 of Ontario's Family Law Act, 'spouse' for support purposes includes — beyond married couples — two categories of cohabitants: (1) continuous cohabitation of 3+ years in a conjugal relationship, OR (2) relationship of some permanence with a child of the relationship (this category does NOT require 3 years).
Detailed Answer
What counts as a 'conjugal relationship'? Courts weigh: shared residence; financial interdependence (joint accounts, shared rent or mortgage); sexual relationship; public presentation as a couple; joint vacations and family activities; recognition of the relationship by children, family, and friends. It's not about whether you signed a cohabitation agreement — it's about the actual nature of the relationship.
Common-law vs married — key differences: (1) spousal support eligibility — same standards apply once the conditions are met; (2) three entitlement bases — compensatory, non-compensatory, contractual all apply; (3) SSAG calculation — same formulas; (4) property division — this is the critical gap! Common-law partners do NOT have automatic Net Family Property equalization rights. Property disputes must be pursued through common-law remedies like constructive trust, which is harder and more uncertain than statutory equalization.
Two-year limitation period: under the Family Law Act, unmarried cohabitants must claim spousal support within 2 years of separation or risk losing the right. Married couples also face limitation periods, but the 2-year common-law rule is stricter and more frequently missed — a classic 'sleeping rights' trap.
Practical examples: (1) 8-year cohabitation, never married, two children, mother stayed home full-time for last 5 years — meets both '3-year' and 'child of relationship' tests, strong compensatory claim, likely several thousand CAD/month with 4-8 year duration; (2) 2-year cohabitation, never married, one child — doesn't meet 3 years but meets 'permanence + child' test, claim still available; (3) 4-year cohabitation, no children, both employed full-time, comparable incomes — meets 3-year duration but entitlement may be weak, depends on specific compensatory or needs basis.
Special note for clients from China: Chinese law generally does not produce spousal support obligations from unmarried cohabitation. Clients from China often assume Ontario works the same way — a dangerous misunderstanding. Common cross-border complications: couple met and cohabited in China before immigrating to Ontario; one partner came on a work permit dependent on the other and could not work; one partner has Chinese assets undisclosed in Canada.
