The Divorce Process in Ontario, Step by Step

Divorce Coach vs Therapist vs Lawyer Who Does What

When I ask new clients what scares them most, it’s rarely one dramatic thing. It’s the fog — not knowing what happens next, how long it takes, what it costs, or which decisions actually matter. So let’s burn off the fog. Here is the Ontario divorce process, start to finish, in the plain English I wish someone had handed me at the beginning of my own.

One orientation point first: ‘getting divorced’ is really two things. There’s resolving the issues — parenting, support, property — and there’s the divorce itself, the legal end of the marriage. Most of the time, money, and stress lives in the first part. The second is mostly paperwork.

Step 1: Separation — and why your separation date matters

There is no such thing as ‘filing for separation’ in Ontario. You are separated when at least one spouse decides the marriage is over and communicates it — no form, no court, no witness. You can even be separated while living under the same roof, which is common when housing is expensive and kids need stability; what matters is that you’re living independent lives (separate rooms, finances, routines).

Here’s the part almost everyone underestimates: your separation date generally becomes the valuation date for dividing property. The numbers on that day — accounts, debts, home value — anchor the entire financial settlement. Note the date, note the evidence for it (a text, an email, a moved-out bedroom), and start documenting. In a high-conflict divorce, expect the date itself to be disputed if it’s financially convenient to dispute it.

Step 2: Full financial disclosure

Both spouses must exchange complete, honest financial information — income, assets, debts, everything. This isn’t optional and it isn’t a courtesy; agreements built on incomplete disclosure can be set aside later. Practically, this means gathering roughly three years of tax returns and notices of assessment, recent pay stubs, and statements for every account, investment, pension, and debt.

This step is where high-conflict spouses play games — slow-walking documents, ‘forgetting’ accounts, undervaluing businesses. Your best defence is boring and unbeatable: your own meticulous file, built early. (This is exactly what my Divorce Command Center was designed for.)

Step 3: Resolving the issues — four possible routes

Parenting arrangements, child support, spousal support, and property division can be resolved through any of four routes, and the route you choose drives your cost, timeline, and stress more than any other single decision:

  • Negotiation — lawyers (or you, with advice) exchange offers until terms are agreed. Fastest and cheapest when both sides are reasonable.
  • Mediation — a neutral mediator helps you reach agreement. Powerful and cost-effective, but it assumes two people negotiating in good faith. With a high-conflict ex, go in prepared and structured, or choose a more protective route.
  • Collaborative process — both spouses and specially trained lawyers commit to settling without court.
  • Court — the route of last resort, and sometimes the necessary one when the other side won’t disclose, won’t negotiate, or safety is at issue. If a court application starts, expect to attend the Mandatory Information Program (MIP) — a required information session — and then a case conference where a judge helps narrow the issues before anything is decided.


The numbers that decide the issues aren’t mysterious, by the way. Child support follows the Federal Child Support Guidelines tables, based mainly on the payor’s income and number of children. Spousal support is guided by the Spousal Support Advisory Guidelines (SSAG) ranges. Property division follows Ontario’s equalization system — I’ve written a full plain-English guide to that here

Step 4: The separation agreement (or court order)

Whatever you resolve gets written into a legally binding document — a separation agreement if you settled it yourselves, or a court order if a judge decided. For a separation agreement to hold up, each spouse needs independent legal advice, and disclosure must have been honest. This document governs your next chapter: don’t rush it, and don’t sign anything under pressure. Support terms can be filed with the Family Responsibility Office (FRO), which enforces payments so you’re not chasing them personally.

Step 5: Filing for the divorce itself

Most Ontario divorces proceed on the ground of one year of separation. (Adultery and cruelty exist as grounds, but they’re rarely used — they must be proven and they don’t improve your financial outcome.) You can file the application before the year is up; the divorce is simply granted after it passes. If you agree on everything, a joint or uncontested application is largely a paperwork exercise — court filing fees total roughly $670, paid in stages, and many people complete this step with minimal legal help.

Step 6: The divorce order and certificate

The court grants a Divorce Order, which takes effect 31 days later. After that, you can request the Divorce Certificate — the document you’ll need if you remarry. That’s it. The marriage is legally over; the rebuilding chapter begins.

How long does it all take, and what does it cost?

An uncontested divorce where everything is agreed: often 4–6 months from filing to order, with costs in the hundreds to low thousands. A contested, high-conflict file: one to three years is realistic, with legal costs commonly in the $15,000–$30,000+ range per spouse. Read those two sentences again — the gap between them is the financial case for staying strategic, documented, and un-baitable, which is precisely the work I do with coaching clients.

Frequently asked questions

Do we have to live in separate homes to be separated?

No. Separated under one roof is legally recognized — what matters is living independent lives. Document the change in arrangements.

There’s no legal requirement, and simple uncontested divorces are often done with minimal help. But get independent legal advice before signing any separation agreement, and get a lawyer involved early if children, significant assets, or a high-conflict spouse are in the picture. Limited-scope retainers make this affordable.
For the divorce and the finances — essentially no. Ontario runs a no-fault system; bad behaviour in the marriage doesn’t buy a better property split. Conduct matters mainly where it affects parenting or where litigation conduct (hiding assets, breaching orders) triggers costs consequences.
