Do the matrimonial home rules apply to common-law couples in Ontario?

No. They apply to married spouses only.

Ontario’s Family Law Act defines a spouse, for property purposes, as either of two persons married to each other, or who together entered into a marriage that is voidable or void in good faith. Part I of the Act, which creates the equalization payment, and Part II, which creates the matrimonial home protections, both run on that definition. A couple who lived together without marrying sits outside both parts, so a home they lived in together does not acquire matrimonial home status at all. What that status is, and what it does for a married couple, is set out on its own page.

Three consequences follow, and each one surprises somebody every year. There is no equalization, so each of you keeps your own property and the increase in its value. There is no equal right of possession, so a partner who is not on title has no automatic right to remain in the home. And there is no consent rule, so the registered owner can list, sell or mortgage the property without the other partner’s permission.

The three year rule is where almost everybody gets caught. Section 29 of the Act does extend the word spouse to two people who have cohabited continuously for at least three years, or who are in a relationship of some permanence and are the parents of a child. That extension applies to Part III, which is support. It does not reach Part I or Part II. Three years of living together can create a spousal support obligation and still leave you with no claim on the house.

A partner who is not on title is not necessarily without a remedy. Someone who contributed financially, or in another way, to property the other holds title to may be able to advance a claim, as unjust enrichment or as a trust claim over the property itself. Those claims turn on the facts and the documents, they are difficult to prove, and they belong with a family lawyer. We do not assess them, and neither should anyone who is not one.

If both of your names are on title, you are co-owners and the house sells the way any jointly owned house sells. Both of you sign, and neither can transfer the whole property alone, not because the Family Law Act says so but because you each own a share of it.

What changes any of this is a written agreement. A cohabitation agreement or a separation agreement can give a common-law partner rights the Act does not, and neither is enforceable unless it is in writing, signed and witnessed. Our post on common-law separation covers what each one can do.
