Common-Law Separation in Ontario

More couples in Ontario are choosing to live together without marrying. Common-law relationships can be just as committed and long-lasting as marriages, but when they end, the law does not always treat them the same way. If you are separating from a common-law partner, or you simply want to understand where you stand, here is an overview of how property and support generally work.

Who is a common-law partner in Ontario?

There is no single definition. Different laws use different tests. For example, the federal government may treat you as common-law for tax purposes after 12 months of living together. Under Ontario's Family Law Act, the test depends on which issue you are dealing with. That is why it is important to look at the specific question, such as property or spousal support, rather than relying on a general label.

Property division: the biggest difference

For married spouses, the Family Law Act sets out a process called the equalization of net family property. In simple terms, each spouse calculates the growth in their net worth during the marriage, and the spouse with the larger increase generally pays the other half the difference. The matrimonial home also receives special treatment for married spouses.

These equalization rules do not apply to common-law partners in Ontario. When a common-law relationship ends, there is no automatic sharing of property acquired during the relationship. As a starting point, each person generally keeps what is in their own name.

That does not always mean the story ends there. Depending on the circumstances, a common-law partner may have other legal claims, for example where one partner contributed significantly to property owned by the other. These claims are based on fairness principles developed by the courts, and they depend heavily on the facts, so early legal advice matters.

What about the home?

If the home is registered in both names, both partners generally have an ownership interest in it. If it is registered in only one partner's name, the other partner does not have the same automatic right to stay in the home that a married spouse would have under the Family Law Act. Any claim to an interest in the home would depend on the facts and the legal claims available.

Spousal support can still apply

While property rules differ, spousal support is one area where common-law partners may have rights similar to married spouses. Under Ontario's Family Law Act, common-law partners can be considered "spouses" for support purposes if they:

• lived together continuously for at least three years, or

• are in a relationship of some permanence and are the natural or adoptive parents of a child.

If you qualify, the next questions are whether support is appropriate in your situation and, if so, how much and for how long. These depend on factors such as the length of the relationship, each person's role during it, and current incomes.

Children are protected either way

Whether parents were married, common-law, or never lived together, the rules for children are the same. Parenting arrangements are decided based on the best interests of the child, and child support is generally calculated using the Federal Child Support Guidelines.

Practical steps if you are separating

1. Gather financial information. Collect recent tax returns, CRA Notices of Assessment, pay stubs, and statements for bank accounts, investments, RRSPs, pensions, and debts.

2. Document contributions. If you contributed to a property owned by your partner, such as mortgage payments or renovations, keep records.

3. Think about the children first. A clear, child-focused parenting plan helps everyone through the transition.

4. Get advice before signing anything. A separation agreement can resolve property, support, and parenting issues, but each partner should receive independent legal advice before signing.

Planning ahead: cohabitation agreements

If you are living together, or planning to, a cohabitation agreement allows you to decide in advance how property and support would be handled if the relationship ends. It can bring clarity and peace of mind to both partners.
