Divorce in Ontario: Understanding the Basic Process

The Basics: What a Divorce Legally Does

A divorce is the legal process that ends a marriage. It is a separate legal step from separating — married spouses can live separately, divide belongings, and even work out parenting arrangements without ever being divorced, since separating does not, on its own, end a marriage. Divorce is generally handled by the courts under a federal law, the Divorce Act, which sets out who can apply, on what grounds, and what a court generally needs to be satisfied of before granting one.

This page gives a general, plain-language overview of how the divorce process typically works in Ontario, from the legal grounds through to a general sense of timing. It is meant as a starting orientation rather than a complete procedural manual. For the fuller reference on eligibility, forms, and step-by-step detail, see our complete guide to divorce in Ontario. If you have not yet separated, or want to understand how separation and divorce relate to one another, our guide to separation versus divorce is a useful starting point.

Grounds for Divorce: Separation Is the Most Common Path

Under the federal Divorce Act, a court generally needs a recognized ground before it can grant a divorce. The ground used by most applicants, by a wide margin, is having lived separate and apart for at least one year. The Act also recognizes adultery and cruelty as grounds, but relying on either of these generally requires proving specific conduct to the court's satisfaction, which is why most people find the one-year separation ground to be the simpler and more commonly used path.

Relying on separation as the ground does not mean you need to wait a full year before doing anything. Many people begin gathering documents, getting oriented on parenting and finances, and even preparing their application well before the one-year mark arrives — see our guide to what to do first after separating for a general starting point. What generally cannot happen sooner is the court granting the divorce itself on this ground, since the one-year period is the legal requirement, not just a guideline.

Who Can Apply, and Where

Generally, at least one spouse needs to have lived in Ontario for at least one year immediately before starting the application, and the application is generally filed in the region where either spouse lives. Either spouse can apply on their own, or both spouses can apply together as a joint application — see our guide to joint divorce for how that option compares to a one-spouse application.

It is worth remembering that applying for a divorce is specifically about ending the marriage. Parenting, support, and property issues are generally separate legal questions that can be addressed alongside a divorce application, resolved by separation agreement beforehand, or dealt with through their own court process — they are not automatically decided just because a divorce is granted.

The General Application Process

The steps below reflect a general pattern many divorce applications follow in Ontario. Your own experience may look somewhat different depending on whether you are applying alone or jointly, and whether any related issues are being resolved at the same time.

1. Confirm you meet a ground for divorce

   For most applicants, this means having lived separate and apart for at least one year. See Grounds for Divorce above.

2. Decide whether to apply alone or jointly

   A joint application generally means both spouses are applicants from the start, which can simplify some later steps. See joint divorce for how this compares to applying alone.

3. Prepare and file the application with the court

   This generally includes supporting documents such as a marriage certificate. See documents to collect for a general starting list.

4. Serve your spouse, if applying alone

   A one-spouse application generally needs to be formally served, after which your spouse generally has a set period of time to respond.

5. Address any parenting, support, or property issues, if relevant

   These can generally be resolved by agreement, included in the same court file, or handled separately — see parenting plans and property division for general starting points.

6. Wait for the court's review and required clearance checks

   This generally includes a federal check confirming no competing divorce proceeding exists, discussed further in How Long the Process Can Generally Take below.

7. Receive the divorce order, then wait out the 31-day period

   A divorce generally does not become final until 31 days after a judge grants it. See After the Divorce Is Granted below.

Uncontested vs. Contested Divorce at a Glance

Whether your divorce is uncontested or contested has a significant effect on which general path it follows. The table below gives a high-level comparison; for the fuller picture on each, see our guides to uncontested (Simple) divorce and contested divorce.

An application can also change categories partway through — one that starts out looking uncontested can become contested if a spouse later disagrees with the divorce or raises a related issue, which generally shifts the case into the longer, regular process.

How Long the Process Can Generally Take

There is no single number that applies to everyone, but a few general patterns are worth knowing. An uncontested divorce commonly takes something in the range of a few months from filing to the divorce order, once required steps like a federal clearance check and the court's own review are complete. A contested divorce, moving through Ontario's regular family court process with conferences and sometimes a trial, can generally take considerably longer — often a year or more — though the exact length varies enormously based on how many issues are in dispute and how cooperative both sides are being.

Several general factors can add time to either kind of case: how busy a particular courthouse is, incomplete or inconsistent paperwork, difficulty locating a spouse who needs to be served, or missing supporting documents such as a marriage certificate. None of these are unusual or a sign that something has gone wrong — they are simply common realities of a formal court process.

Timelines vary by court and by case. This page describes general patterns only, not a prediction for your file. Processing times differ between courthouses, and can also change over time as court volumes shift. If timing genuinely matters for your situation — for example, around a specific event or deadline — consider getting individualized legal advice rather than relying on a general range.

After the Divorce Is Granted

One detail that surprises many people: even once a judge signs a divorce order, the divorce is not immediately final. Under the federal Divorce Act, a divorce generally does not take effect until the 31st day after the judge grants it, a period built in to allow time for either spouse to file an appeal. You cannot remarry, and the marriage has not legally ended, until that period has passed without an appeal being filed.

Once the 31-day period has passed, a certificate of divorce confirming the date the marriage legally ended is generally available on request. Our complete guide to divorce in Ontario covers what generally happens after this point in more detail, including practical matters like updating your name or other records.

Getting Help Along the Way

Even a straightforward, uncontested divorce involves formal paperwork and legal requirements, and it is common to want a second set of eyes before filing, especially if parenting, support, or property issues are being addressed at the same time. Getting independent legal advice — rather than relying only on general information or a shared understanding with your spouse — is generally considered good practice, particularly before signing a separation agreement or anything else that resolves a related issue. See our guide to independent legal advice for what that generally involves.

If your situation involves a genuine dispute, or you are simply unsure whether your circumstances point toward an uncontested or a contested path, that is also a reasonable moment to seek advice early, since it can help you plan around a more realistic general timeline from the outset rather than adjusting course partway through.
