Same-Sex Divorce in Ontario: Does the Process Differ?

If you're a same-sex married couple in Ontario considering divorce, here's the short answer: the process is exactly the same as it is for any other married couple. Same statute, same court, same forms, same grounds. There's no separate track and no extra hurdle simply because both spouses are the same gender.

Where things can get genuinely more complicated is when a same-sex couple married outside Canada — particularly in a country that didn't recognize same-sex marriage at the time, or still doesn't. This guide covers what stays identical and where you should actually pay closer attention.

What's Identical, Full Stop

Ontario's Divorce Act — the federal law that governs how a marriage legally ends — doesn't distinguish between spouses based on gender in any way. For every married couple, same-sex or not:

• The same court has jurisdiction: the Superior Court of Justice. The Ontario Court of Justice cannot grant a divorce for anyone.
• The same grounds apply: you generally need to show the marriage has broken down, most commonly demonstrated by living separate and apart, or in less common cases by a spouse's adultery or cruelty.
• The same "corollary relief" is available: decision-making responsibility, parenting time, contact, child support, and spousal support all use the same tests and terminology regardless of the spouses' genders.
• If you own property together, the same Family Law Act equalization and matrimonial home rules apply to married same-sex spouses exactly as they do to married opposite-sex spouses.
• The same residency rule applies: at least one spouse generally needs to have been habitually resident in Ontario for a set period immediately before filing.

There's no separate application form, no separate court stream, and no additional documentation required purely because of the spouses' genders.

Where things do get more complex is around marriages performed outside Canada, or a couple's current country of residence — not the Ontario divorce process itself.

If You Married in a Country That Didn't Recognize Same-Sex Marriage

Canadian federal law permits same-sex marriage nationally, and it also includes a narrow, specific pathway allowing some couples who married in Canada — including couples who came here specifically because same-sex marriage wasn't available where they lived — to obtain a Canadian divorce even if they wouldn't otherwise meet the usual residency test. This provision is technical and fact-specific, so if it might apply to you, get advice from a family lawyer early rather than assuming either way.

If You Now Live in a Country That Doesn't Recognize Your Marriage

As a general rule, whether Canada treats your marriage as valid turns on whether it was validly performed where and when it took place — not on whether your current country of residence recognizes same-sex marriage today. That said, how your divorce will later be recognized in that other country is a separate question from how Canada treats your marriage, and it depends on that country's own law, not Ontario's. If you expect to need your divorce recognized somewhere that doesn't recognize same-sex marriage, raise that with a lawyer before you file, not after.

Residency and Jurisdiction Still Apply the Same Way

Ordinarily, Ontario's Superior Court of Justice has jurisdiction over a divorce where at least one spouse has been habitually resident in the province for at least one year immediately before the proceeding starts (this residency rule is set by federal statute and is worth confirming hasn't changed before you rely on it). Same-sex couples meet this test the same way anyone else does — through where they actually live, not where they married.
