Key takeaways
  • Separation is a fact about how you live, not a status a court grants, and a divorce is not required afterward.
  • For a divorce based on separation, spouses must have lived separate and apart for at least one year before the divorce is decided.
  • Support, parenting and property questions can be dealt with after you separate, whether or not you ever divorce.

Many people search for "legal separation" expecting a form to file or a court status to apply for. In Ontario, it doesn't really work that way, and that surprises a lot of couples.

This article explains what separation means in practice, how it differs from divorce, and which legal questions it can set in motion. It is general information, not advice for your situation.

Separation is a fact, not a court order

Separating generally means that you and your spouse or partner have ended your relationship and are living apart, or living separate lives. It is something that happens in real life. You do not need a judge to approve it.

A divorce is not required after you separate. Provincial law, in Ontario the Family Law Act and the Children's Law Reform Act, deals with support and parenting for married couples who separate but do not apply for a divorce, and for unmarried couples.

How separation differs from divorce

QuestionSeparationDivorce
Does it end the marriage?NoYes. It usually takes effect on the 31st day after the judgment granting it
Is a court judgment needed?NoYes, a judgment under the Divorce Act
Who can be separated?Married and unmarried couplesMarried spouses
GroundNot applicableBreakdown of the marriage

Under the Divorce Act, the only ground for divorce is breakdown of the marriage. One way to show breakdown is that the spouses lived separate and apart for at least one year before the divorce is decided and were living apart when the proceeding started.

The one-year rule and its exceptions

You do not have to wait a year before applying, as long as you are living apart when you apply. The year must have passed before the divorce is granted.

What separation can affect

Because the date you separated matters for property and for deadlines, it is worth noting it down and confirming it with a lawyer if you and your former partner see it differently.

What to do next

Frequently asked questions

Is there a legal separation form in Ontario?

Separation is generally a matter of how you live, not a status granted by a court. Rights about support, parenting and property can still be dealt with under provincial law even if you never divorce.

Do I have to divorce after separating?

No. A divorce is not required after separating, and provincial law covers support and parenting for couples who separate without divorcing.

Can we try to get back together without restarting the one-year clock?

Possibly. Living together again does not interrupt the one-year separation if it lasted no more than 90 days in total and its main purpose was reconciliation.

Do I need a written agreement when we separate?

It is not required to separate, but it helps to record what you agree. A written agreement on child support, parenting arrangements or spousal support must be signed by both parents or caregivers in front of a witness.
