How Does Divorce Work in Ontario? A Step-by-Step Guide

Most people who search "how does divorce work in Ontario" are trying to answer one underlying question: what actually has to happen before I'm legally divorced? The honest answer is that "the divorce" — the piece of paper that dissolves your marriage — is often the simplest part of separating. The harder, longer part is usually resolving everything the divorce doesn't cover on its own: who the kids live with, who pays support, and how property gets divided.

This guide walks through both halves, in order, so you know what you're actually signing up for.

Step 1: Understand what "getting divorced" legally means

In Ontario, a divorce is governed by the federal Divorce Act. All it does is legally end the marriage. It does not, by itself, decide:

Parenting arrangements (what the Divorce Act now calls decision-making responsibility and parenting time)
Child or spousal support
Division of property

Those issues — collectively called "corollary relief" — are handled separately, either under the Divorce Act (support and parenting) or Ontario's Family Law Act (property equalization). You can get divorced quickly if those issues are already resolved or aren't contested. You can also be waiting on a parenting or property dispute for a long time while the underlying divorce itself sits ready to be finalized in a single afternoon of paperwork.

This distinction is the single most common source of confusion for new clients, so it's worth sitting with before anything else.

Step 2: Confirm you meet the legal grounds

Under the Divorce Act, you have to show the marriage has broken down. There are three ways to establish that, and one is used in the overwhelming majority of cases:

Separation — you and your spouse have lived separate and apart for at least one year. You don't have to wait out the year before filing; you just can't be granted the divorce until it's complete. The Act allows up to 90 days of attempted reconciliation during that year without resetting the clock.
Adultery — your spouse committed adultery.
Cruelty — your spouse's physical or mental cruelty made continued cohabitation intolerable.

Separation is almost always the path used, because adultery and cruelty require proving fault in court, which adds cost, delay, and conflict most people are trying to avoid.

You'll sometimes hear Canada described as having "no-fault divorce." That's a fair description of how it plays out for nearly everyone in practice — separation alone gets you to the same result without having to prove anyone did anything wrong, and marital misconduct generally doesn't affect how support or property get divided. But it's not literally accurate: adultery and cruelty remain valid legal grounds under the Act. They're just rarely worth using.

You also need residency: at least one spouse must have lived in Ontario (or another Canadian province or territory) for at least one year immediately before starting the application.

Step 3: Decide whether it's a joint or sole application

Joint application: both spouses apply together, having already agreed on the divorce and (ideally) on parenting, support, and property. This is faster and less adversarial — there's no one to "serve," because both of you signed the application.
Sole application: one spouse applies and then formally serves the other with the paperwork. If the other spouse doesn't dispute it, it proceeds largely like a joint application from there. If they file an Answer disputing something, the case becomes contested and moves into case conferences, disclosure, and possibly a trial.

Whether you should file jointly often becomes clear only once Step 4 is underway.

Step 4: Resolve the corollary issues (this is usually the real timeline driver)

Before — or alongside — finalizing the divorce, you and your spouse need to work out parenting, support, and property division. This is where the bulk of the time, cost, and conflict in a separation actually lives, and it can happen through several paths:

Negotiation between lawyers
Mediation, with or without lawyers involved
Collaborative family law, where both spouses and their lawyers commit to resolving things without going to court
Litigation, when an agreement isn't possible and a judge needs to decide

An uncontested, well-documented separation agreement can let you move to the divorce application quickly. A contested property or parenting dispute can take considerably longer than the divorce itself — sometimes years, in genuinely contested cases — because it moves through the Family Law Rules' case conference and motion process rather than a simple paper review.

Step 5: Gather your documents

At minimum, you'll need your original marriage certificate. If you were married in Ontario and don't have it, you can request one through ServiceOntario or the Office of the Registrar General. If you were married outside Canada, a certified translation is required if the original isn't in English or French.

If support or property division is in issue, you'll also need financial disclosure — income documents, statements of property, and related records — but that's driven by the corollary relief process, not the divorce application itself.

Step 6: File the Application for Divorce

The application is filed with the Superior Court of Justice (or, in areas with a Unified Family Court — including London — that same court handles it under one roof). This can typically be done through Ontario's online filing portals (the Ontario Courts Public Portal in the Toronto region, or Family Submissions Online elsewhere).

If you're filing solely, the next step is formally serving your spouse and waiting out the response period. If they file an Answer, the file becomes contested at this point.

Step 7: File the Affidavit for Divorce

Once the one-year separation is complete (or the relevant grounds are otherwise established) and any corollary issues are resolved or not in dispute, you file an Affidavit for Divorce (Form 36) asking a judge to grant the divorce. In most uncontested cases, a judge reviews this on paper — no court appearance required.

Step 8: The Divorce Order — and the 31-day wait

If the judge is satisfied, they grant a Divorce Order. It doesn't take effect immediately: by law, it becomes effective 31 days after it's made. That window exists to allow time for an appeal. You are not divorced until that period has run.

Step 9: Get your Certificate of Divorce

After the 31 days pass, either spouse can request a Certificate of Divorce from the court. This is the official proof of your divorce date — you'll need it if you plan to remarry or if any institution asks for formal confirmation.

What this actually costs and takes

Two things drive cost and timeline, and they're different questions:

The divorce itself, when uncontested and the one-year separation has already run, is largely a matter of paperwork and court processing time — often a matter of a few months from filing to Divorce Order once you're eligible to apply. Court filing fees for a divorce application currently run in the range of a few hundred dollars, split between the initial filing and the final affidavit stage — worth confirming the exact current figure against the court's fee schedule, since these are periodically adjusted.

The corollary issues — parenting, support, property — are the real variable. A fully agreed separation can move in parallel with minimal added time. A contested dispute over parenting time or property equalization can extend the process well past a year, independent of the 31-day divorce window entirely.

Common questions

Do I need my spouse's consent to get divorced? No. If your spouse won't cooperate, you can file a sole application and serve them. If they don't respond within the required period, the case generally proceeds as if uncontested. If they file an Answer disputing the divorce or the corollary issues, it becomes contested.

Can I get divorced without going to court in person? In most uncontested cases, yes. The judge reviews the Affidavit for Divorce (Form 36) on paper. A court appearance is typically only needed if the matter is contested or the judge has questions the paperwork doesn't answer.

Does finalizing the divorce automatically divide our property? No. Property equalization under the Family Law Act is a separate process from the divorce itself. It's worth noting that in Ontario, a former spouse generally has six years from the date of separation — or two years from the date of divorce, whichever comes first — to bring an equalization claim, so this isn't something to let sit indefinitely; confirm current limitation periods with a lawyer before assuming you're past the deadline either way.

What if I don't know where my spouse is? There are court procedures for substituted service (serving through another method, such as a last known address or a person likely to reach them) when a spouse genuinely can't be located. This requires a motion to the court — it isn't something you can decide on your own.

Can we still get divorced if we agree on everything? Yes — this is the joint application path, and it's typically the fastest and least expensive route through the process, provided the one-year separation requirement (or another ground) is already met.

Is common-law separation the same process? No. Common-law couples in Ontario aren't married, so there's no divorce to obtain — but property, support, and parenting issues still need to be resolved, and the rules governing property division in particular are meaningfully different from what applies to married spouses.

Where a lawyer actually changes the outcome

None of the above requires a lawyer as a matter of law — you can self-represent. Where a lawyer earns their fee is almost never the paperwork itself; it's in:

Making sure the separation agreement underneath the divorce actually protects you — on property, support, and parenting — rather than just being fast
Catching issues in disclosure that change what you may be entitled to
Keeping a contested matter from drifting into unnecessary cost and delay
Making sure the divorce order and any corollary orders are actually enforceable down the road
