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
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.

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.
