Key takeaways
  • Ontario divorce is based on breakdown of the marriage, shown by one year of living separate and apart.
  • The one-year period is not interrupted if spouses resumed cohabitation for periods totalling not more than 90 days with reconciliation as the primary purpose.
  • The court has a duty to satisfy itself that there is no possibility of reconciliation, unless that is inappropriate.
  • How a longer or mixed-purpose reunion affects your clock depends on the facts and is worth confirming with a lawyer.

Many couples try again before they accept that a marriage is over. If you moved back in together, even briefly, you may worry that the year you had already counted has been wiped out.

The Divorce Act deals with this directly, and the rule is more forgiving than many people expect. This article explains how the 90-day rule works, what it does not say, and how to keep track of your dates. It is general information, not legal advice.

The one-year separation rule

The only ground for divorce is breakdown of the marriage. It is established where the spouses have lived separate and apart for at least one year immediately preceding the determination of the divorce proceeding. Spouses are deemed to have lived separate and apart for any period during which they lived apart and either of them intended to live separate and apart from the other.

Separately, an Ontario court has jurisdiction only if either spouse has been habitually resident in the province for at least one year immediately before the proceeding starts. That residence test is different from the separation test, though many people meet both at the same time.

What the 90-day rule says

The Act protects couples who attempt to reconcile. The one-year period is not interrupted or terminated if the spouses resumed cohabitation for a period, or periods totalling, not more than 90 days with reconciliation as its primary purpose.

Three details matter. First, the 90 days is a total across all attempts, not a limit per attempt. Second, the purpose has to be reconciliation, as the primary purpose. Third, the rule speaks to whether the clock is interrupted. How the days you lived together are counted is worth confirming with a lawyer.

SituationEffect on the one-year period
One or more attempts to reconcile, totalling 90 days or less, with reconciliation as the primary purposeThe one-year period is not interrupted or terminated
Cohabitation totalling more than 90 daysThe rule in F4 no longer protects the period, so the effect depends on the facts and should be checked with a lawyer
Living together mainly for another reason, such as cost or convenienceNot covered by the reconciliation wording; whether you still count as separated depends on the facts

If you are close to the 90-day line, or unsure what the primary purpose was, get advice before you file.

Why the dates matter beyond the divorce

The separation date is not only about when you can divorce. For property, net family property is the value of property at the separation date, minus debts and excluded property, less the same net value at the date of marriage, and the spouse with the larger amount pays half the difference as an equalization payment. Court applications for an equalization payment must be made within six years of separation or two years after the divorce is final, whichever comes first.

Where the separation date is placed can therefore change the numbers and the deadlines. If you and your spouse see the reunion differently, one of you may argue for a different date. How a reconciliation attempt affects the date used for property is a question for a lawyer, because it turns on the facts.

Reconciliation, the court and your children

In a divorce proceeding, it is the court's duty to satisfy itself that there is no possibility of reconciliation of the spouses, unless the circumstances make that inappropriate. It is one of the court's checks, and a genuine attempt that failed is part of your history.

If you have children, the court must be satisfied that reasonable arrangements have been made for their support before granting a divorce. Spouses must also, to the best of their ability, protect any child of the marriage from conflict arising from the proceeding. A reunion that ends badly can be hard on children, so keep their routine steady.

If you need orders while you sort things out, parties commonly ask for temporary orders on child or spousal support, parenting schedules, or who lives in the family home. If safety is a concern at any point, a restraining order is available to people who were married or lived together for any period, or who have a child together.

What to do next

Good records are the most useful step you can take, because the 90-day rule depends on dates and purpose.

If your spouse files first, a respondent served in Canada or the United States must serve and file an Answer (Form 10) within 30 days. Do not wait to get advice.

Frequently asked questions

Does moving back in together restart the one-year clock?

Not necessarily. The one-year period is not interrupted if the spouses resumed cohabitation for a period, or periods totalling, not more than 90 days with reconciliation as its primary purpose. Longer or different reunions depend on the facts.

Is the 90 days per attempt or in total?

The rule refers to a period, or periods totalling, not more than 90 days. That wording points to a combined total across attempts.

Do the days we lived together count toward the year?

The 90-day rule says the period is not interrupted or terminated. The year itself is measured as time lived separate and apart, so confirm with a lawyer how your days will be counted.

Will a failed reconciliation affect property?

Property is valued at the separation date, so the date used can matter. Whether a reconciliation attempt changes that date depends on your facts, so get advice before you assume.
