Key takeaways
  • Ontario has no special legal status called a trial separation, so what counts is how you live and what each of you intends.
  • Spouses can try to reconcile for up to 90 days in total without interrupting the one-year separation period for divorce.
  • The date you separate can fix the valuation date for dividing property, so it is worth recording honestly.

Many couples take a break before deciding whether the relationship is over. You might be living in different places, or under one roof in separate rooms, and you may both hope things improve. It is natural to wonder whether this break already has legal effects.

This page explains how Ontario and federal law treat separation, reconciliation attempts, divorce timing and property. It is general information, and a lawyer can apply it to your situation before you rely on any date.

Is a trial separation a legal separation?

There is no formal step or registration that makes a separation official. For divorce, spouses are treated as having lived separate and apart for any period during which they lived apart and either of them intended to live separate and apart. Only one spouse needs that intention.

For dividing property, the valuation date is the earliest of several dates. The first of those is the date the spouses separate and there is no reasonable prospect that they will live together again. That wording means the realistic chance of getting back together can matter, so a break that both of you genuinely expect to end soon may be viewed differently from a final split.

Some couples separate but keep living in the same house. Justice Canada notes that a lawyer can explain the factors courts consider when deciding whether spouses are separated. How a court would see your arrangement depends on the facts.

The 90-day reconciliation rule

If you try to reconcile, the Divorce Act protects the separation period up to a point. The one-year separation period is not interrupted if the spouses resume cohabitation for one period, or several periods totalling, not more than 90 days with reconciliation as the primary purpose.

Justice Canada describes the same idea in practical terms: spouses can live together for up to 90 days, either before or after filing the divorce application, to try to reconcile. If it does not work out, the divorce can continue as if they had not spent the time together.

How a trial separation affects divorce

Marriage breakdown for a divorce is established if the spouses have lived separate and apart for at least one year immediately before the court decides the divorce, and were living separate and apart when the proceeding started. A trial separation that turns permanent can therefore become the start of that year.

There are other routes. Breakdown can also be established without the one-year period if the other spouse committed adultery, or treated you with physical or mental cruelty that makes continued cohabitation intolerable.

If one spouse becomes unable to form an intention to continue living separate and apart, the separation period is not interrupted only for that reason, if the court finds the separation would probably have continued.

Effects on property, the home and benefits

IssueWhat to know
Property divisionWhen married spouses separate, the spouse with the smaller net family property is entitled to one-half of the difference between the two.
ValuationProperty you owned at separation is valued as of the day you separated.
Time limitAn equalization application cannot be brought after the earliest of two years after divorce, six years after separation with no reasonable prospect of resuming cohabitation, or six months after the first spouse's death.
The homeBoth spouses have an equal right to possession of a matrimonial home, whoever holds title.
Common-law partnersCommon-law couples are not legally required to split property acquired while living together, and items generally belong to whoever bought them.
SupportFor support claims, two unmarried people who cohabited continuously for at least three years, or who have a child and a relationship of some permanence, are covered.

For tax benefits, the CRA says to report a separation only after you have been separated for more than 90 days because of a breakdown in the relationship. The effective date is the day you started living apart. For common-law status, the 12 continuous months of living together includes any period you were separated for less than 90 days.

What to do next

Frequently asked questions

Does a trial separation start the one-year divorce clock?

Spouses are treated as living separate and apart for any period they lived apart and either of them intended to. Whether your break qualifies depends on how you lived and what each of you intended, so keep a record.

Can we try to reconcile without restarting the clock?

Yes, within limits. The one-year period is not interrupted if you live together for one period, or several totalling, not more than 90 days with reconciliation as the primary purpose.

Do I have to tell the CRA about a trial separation?

The CRA says to report a separation only after you have been separated for more than 90 days because of a breakdown in the relationship. A change must then be reported by the end of the month after the month the status changed.

Can my spouse make me leave the home during a trial separation?

Both married spouses have an equal right to possess the matrimonial home, whoever holds title, and without a court order a non-owning spouse cannot be put out simply because the other owns it. These rules apply to married spouses, so unmarried partners should get advice about their rights and options.
