Family mediation in Ontario — how it works and what it costs

Family mediation in Ontario is a process where a neutral third party — the mediator — helps both spouses reach an agreement on parenting, support, or property without going to court. The mediator does not make decisions. They run the conversation, structure the issues, and help both sides find common ground. Whatever you agree gets written into a separation agreement (or a court order, if a court file is already open). Most Ontario family files that settle without litigation settle through mediation or assisted negotiation, not court.

There are two streams in Ontario: court-connected mediation (subsidized or free, available at every courthouse) and private mediation. Court-connected services are run by the Ministry of the Attorney General (the MAG) (ontario.ca/page/family-mediation-services). Private mediation is provided by OAFM-accredited mediators (the Ontario Association for Family Mediation, the profession's accrediting body) — usually family-law lawyers or social workers with mediation training.

What can family mediation settle?

Parenting time and decision-making, child support, spousal support, division of property, and the matrimonial home — the same issues a judge would decide, settled across a table instead. Mediation does not require agreement up front; it requires willingness. It works when both spouses can negotiate in good faith, in person or virtually. Mediation cannot grant the divorce itself — that stays a court order — but it can settle everything underneath it, so the divorce becomes paperwork.

Court-connected vs private mediation

Court-connected mediation is available at every Ontario courthouse, before or during a court case. The on-site service at the courthouse is free; off-site mediation through the court-connected program charges a sliding-scale fee based on income. Private mediation typically runs $300 to $500 per hour, usually split between spouses, with most files resolving in 6 to 15 hours over two to four months.

Stream	Court-connected	Private
Cost	Free on-site; sliding scale off-site	$300–$500/hr, often split
Provider	MAG-run accredited mediator	OAFM-accredited lawyer or social worker
Best for	Cost-sensitive, court-adjacent files	Complex files needing continuity

Court-connected fits cost-sensitive files and cases already near a courtroom, often booked around a case conference — the first meeting with a judge in a family court file. Private mediation fits more complex files where you want continuity with one mediator across every session.

How much does mediation cost in Ontario?

On-site court-connected mediation at the courthouse is free. Off-site court-connected mediation charges a sliding-scale fee based on each spouse's income. Private mediation costs $300 to $500 per hour, and most files take 6 to 15 hours in total — $1,800 to $7,500 per file, usually divided between you. Compare that with a contested court file, which commonly runs $7,500 to $35,000 per side.

What happens if you cannot agree on a mediator?

You do not need to agree on a name to start. In the court-connected stream, the service for your courthouse matches you with an accredited mediator — there is no name to fight over. In the private stream, the usual path is that each of you proposes two or three names from the OAFM directory and you book a short intake call with one you can both accept. If you still cannot land on a name, use the court-connected service, or consider family arbitration — a process where the neutral actually decides.

When mediation is not the right route

Mediation is not right when there is family violence or a power imbalance that stops one spouse from negotiating safely. Mediators screen for this, and many will not take cases involving physical violence; courts will not enforce mediated agreements where coercion is present. It also does not work when one spouse will not participate — the mediator cannot compel attendance. If the other side refuses, the route is court (see the family court process in Ontario and which family court forms you will need) or arbitration. If mediation settles most but not all issues, collaborative divorce is the more structured out-of-court option, with a lawyer at every meeting. See mediation vs litigation for the full comparison.

Is a mediated agreement legally binding?

Not by itself. Mediation produces an agreement in principle. It becomes binding when it is written into a formal separation agreement (or a court order, if a file is open) and signed by both spouses — ideally after each of you takes independent legal advice, a short review with your own lawyer or paralegal. Until that step, what you agreed in the room is a plan, not a contract.

How to start mediation this week

If you and your spouse are still talking — even with strain — try court-connected mediation first. It is free at the courthouse and low-cost off-site, and the mediators are accredited. Book through the courthouse closest to where you live; the booking line is on the Ontario family mediation services page. For a more complex file, look for an OAFM-accredited mediator and expect 6 to 15 hours over two to four months.

Either way, bring a written list of what you want to resolve — and bring your numbers. Run your child and spousal support ranges free before the first session, so you negotiate from the table amount instead of a guess. The mediator's job is to help you decide; your job is to know what you are deciding. To see where Cairn fits before you book, see what we do.
