Say the words "common-law marriage" in Ontario and most people nod along like it's an established legal status — something you slide into automatically after a certain number of years together. It isn't. Ontario has never recognized "common-law marriage" as a form of marriage, and the gap between what people assume and what the law actually provides catches long-term couples off guard, often at the worst possible time: separation. Here's what's myth, and what Ontario law gives common-law partners instead.
There Is No Such Thing as "Common-Law Marriage" in Ontario
Ontario law recognizes two distinct things: being legally married, and being common-law partners — a factual description of an unmarried couple in a relationship, often involving cohabitation. There's no third status called "common-law marriage" that functions as a lesser or delayed form of marriage. You're either married, under the law that governs marriage, or you're not, regardless of how long you've lived together or what language you use to describe the relationship.
What People Usually Assume (and Why It's Wrong)
- "We've been together long enough, so we're basically married." Length of cohabitation alone doesn't create marital status or property rights under Ontario's Family Law Act.
- "The house is half mine because I've lived there for years." Living somewhere, even for a long time, doesn't create an ownership interest by itself.
- "We're common-law, so separating is just like a divorce." The process and the entitlements involved are genuinely different — there's no divorce to obtain, and no automatic property equalization to divide.
What Ontario Law Actually Recognizes
| Legal issue | Married spouses | Common-law partners |
|---|---|---|
| Division of property (equalization) | Automatic right under the Family Law Act | No automatic right, regardless of how long you lived together |
| Matrimonial home | Special possession and equalization protections | No equivalent statutory protection |
| Spousal support | Available | Available only if you meet the Family Law Act's separate support-specific test |
| Ending the relationship | Requires a divorce through the Superior Court of Justice | No formal legal process required to separate |
| Domestic contract type | Marriage contract | Cohabitation agreement |
What Common-Law Partners CAN Claim
The myth cuts both ways — some people assume common-law partners have no rights at all, which also isn't true:
- Spousal support, if you meet the Family Law Act's own test for qualifying as a "spouse" for support purposes — generally a minimum period of continuous cohabitation, or a relationship of some permanence together with a child
- A property claim through general trust or unjust enrichment principles — a legally distinct, and generally harder, path than the automatic equalization available to married spouses
- Parenting and child support arrangements for any children, assessed on the same best-interests basis as for any other parents, married or not
Why the Myth Persists
Part of the confusion comes from casual language: people say "common-law marriage" the way they'd say "married," without meaning anything precise by it. Some benefit programs and tax rules also use spousal-style language for common-law couples in specific contexts, which reinforces the sense that the relationships are treated identically everywhere — even though, as this article shows, they often aren't.
Protecting Yourself Instead of Relying on the Myth
- [ ] Don't assume years together creates an automatic property right — it doesn't
- [ ] Talk to your partner about a cohabitation agreement
- [ ] Keep records of who owns and pays for what
- [ ] Update your will and beneficiary designations to reflect your actual wishes
- [ ] Get legal advice before assuming any "automatic" rights apply to your situation
Frequently asked questions
If we call ourselves common-law, doesn't that create legal rights automatically?
No. "Common-law" describes a factual relationship status, not a legal marriage. Some rights, like a possible spousal support claim, can flow from meeting a specific test — but property equalization does not.
Does it matter how many years we've lived together?
It can matter for specific purposes, such as qualifying for a possible spousal support claim, but it does not create property equalization rights no matter how long the relationship lasts.
Is a cohabitation agreement the same as getting married?
No. A cohabitation agreement is a private contract between partners that can address property, support, and related matters, but it doesn't create marital status or the automatic protections that come with being legally married.
Can we just tell people we're "married" for legal purposes if we've been together long enough?
No. Marital status in Ontario depends on whether you were legally married, not on how long you've cohabited or what you call your relationship informally.
