What is a cohabitation agreement in Canada?
A cohabitation agreement is a written contract between two people who are living together or planning to live together outside of marriage. It sets out how property, debts, and support obligations will be handled during the relationship and on separation. In many provinces it is recognized under the provincial Family Law Act.
Do common-law partners have the same property rights as married spouses in Canada?
No. In most provinces, common-law partners do not have the same automatic property division rights as married spouses. In Ontario, for example, the Family Law Act property equalization provisions apply only to married spouses. Common-law partners generally rely on constructive trust claims, which are more complex to establish in court.
Is a cohabitation agreement legally binding in Canada without a lawyer?
Yes, provided it meets the requirements of the provincial family law legislation. Generally it must be in writing, signed by both parties, and witnessed. It is strongly recommended that both parties independently review the agreement, even if neither uses a lawyer, to reduce the risk of a court setting it aside for unconscionability or duress.
What can a cohabitation agreement cover in Canada?
It can address ownership of property brought into the relationship, how property acquired during the relationship is divided on separation, spousal support obligations, treatment of debts, and arrangements for pets or shared assets. It cannot override child support obligations.

Can a cohabitation agreement become a marriage contract if we later marry?
Yes. In Ontario and most provinces, if parties to a cohabitation agreement later marry, the agreement continues to bind them as a marriage contract. You should review and update the agreement at the time of marriage to ensure it reflects your current intentions.
How do the rules differ by province for cohabitation agreements?
Ontario's Family Law Act explicitly provides for cohabitation agreements. British Columbia's Family Law Act gives common-law partners similar rights to married spouses after two years of cohabitation, making a cohabitation agreement particularly important to vary those default rules. Quebec operates under the Civil Code and has no automatic common-law partner property rights.
What makes a cohabitation agreement unenforceable in Canada?
A court may set aside a cohabitation agreement if there was no financial disclosure, if one party was under duress or did not understand the agreement, if it was unconscionable at the time of signing, or if there was fraud or misrepresentation. Full and frank financial disclosure by both parties is essential.

Does a cohabitation agreement need to be notarized in Canada?
No. A cohabitation agreement does not need to be notarized in Canada. It must be in writing, signed by both parties, and witnessed by an independent witness. Some provinces require two witnesses. Review the specific requirements of your province.
What can and cannot be done without a lawyer for a cohabitation agreement?
Drafting, reviewing, and signing a cohabitation agreement can all be done without a lawyer. However, having independent legal advice for each party significantly strengthens the agreement's enforceability. If the agreement is later challenged, a court is more likely to uphold it if both parties had the opportunity to obtain legal advice.
