Divorce Mediation in Ontario: A Step-by-Step Guide

Last updated: August 31, 2026

Divorce mediation can help separating spouses resolve important family law issues without asking a judge to make every decision. With the assistance of a neutral mediator, spouses can work toward agreements about parenting, child support, spousal support, property division, debts and the matrimonial home.

Mediation is often less adversarial and more flexible than court. However, it still requires preparation, honest financial disclosure and independent legal advice. It is not suitable for every family, and it does not replace the court process required to obtain a legal divorce.

Quick answer: In Ontario divorce mediation, a neutral mediator helps separating spouses negotiate their own settlement. The mediator does not decide the outcome or act as either spouse’s lawyer. If terms are reached, each spouse should obtain independent legal advice before signing a properly prepared Separation Agreement.

What Is Divorce Mediation?

Mediation is a form of family dispute resolution. A neutral mediator helps separating spouses:

• Identify the issues that must be resolved
• Exchange relevant information
• Discuss possible solutions
• Communicate more effectively
• Record any terms they reach

The mediator does not make a ruling, determine who is right or force either person to accept a proposal. The spouses remain responsible for deciding whether to settle and on what terms.

Under the federal Divorce Act, lawyers have a duty to encourage clients to try a family dispute resolution process where it is appropriate. Although, mediation is one option, but it is not mandatory in every Ontario family law case.

Mediation and divorce are not the same thing

Mediation can help spouses settle the legal issues arising from separation. It cannot legally end the marriage. Only a court can grant a divorce order.

If all other issues have been resolved in a Separation Agreement, spouses may later apply for an uncontested divorce. If they cannot settle, unresolved issues may proceed through negotiation, arbitration or family court.

What Can Be Resolved Through Divorce Mediation?

Depending on the family, mediation may address:

• Parenting time
• Decision-making responsibility
• Holiday and vacation schedules
• Communication about the children
• Child support
• Special or extraordinary expenses
• Spousal support
• Division of property and debts
• Equalization of net family property
• The matrimonial home
• Pensions, investments and business interests
• Life insurance and security for support
• The process for resolving future disagreements
• The terms of a Separation Agreement

Spouses do not have to resolve everything at once. They may settle some issues in mediation and use another process for the remaining issues.

Open vs. Closed Mediation in Ontario

One important decision is whether the mediation will be open or closed.

Closed mediation

In closed mediation, discussions and proposals are generally confidential and cannot usually be introduced in court. The mediator’s report normally states whether an agreement was reached without describing the negotiations.

Closed mediation is common because it allows spouses to explore settlement options without worrying that every proposal will later be used against them.

Open mediation

In open mediation, the process is not confidential in the same way. The mediator may prepare a report describing what occurred, including offers, conduct or the reasons an agreement was not reached. The mediator may potentially be asked to provide evidence.

Open mediation is less common and should be selected only after both spouses understand its consequences.

Confidentiality has limits

Even in closed mediation, confidentiality is not absolute. Exceptions may apply to concerns about a child’s safety, threats of serious harm or other reporting and legal obligations. The mediation agreement should explain the applicable rules before sessions begin.

Ask the mediator to confirm in writing:

• Whether the process is open or closed
• What documents will be produced
• What information may be disclosed
• Whether the mediator can be called as a witness
• What happens to session notes and records

Step 1: Choose a Qualified Family Mediator

Ontario does not have one universal government licence for all family mediators. Training, experience and professional designations can vary.

Before selecting a mediator, ask about:

• Family law training and experience
• Accreditation or professional designations
• Experience with parenting, support and property disputes
• Family violence and power-imbalance screening
• Whether the mediation will be open or closed
• Whether sessions can be held separately
• Hourly rates, retainers and cancellation fees
• How preparation and document review are billed
• What document the mediator prepares after settlement
• Whether the mediator is comfortable with complex assets or high-conflict cases

A mediator may be a lawyer, mental health professional, social worker or another trained professional. If the case has significant financial or legal complexity, experience with Ontario family law is especially important.

Step 2: Complete Intake and Safety Screening

A responsible family mediator should meet with each spouse separately before joint negotiations begin. This intake process usually explains mediation and determines whether it is appropriate.

Screening may consider:

• Family violence
• Coercive or controlling behaviour
• Threats or intimidation
• Significant differences in bargaining power
• Mental health or substance-use concerns
• A spouse’s ability to understand financial information
• Whether either person feels unable to disagree safely
• Whether urgent court protection is required

Screening should continue throughout the mediation, not only during the first meeting.

A history of conflict or family violence does not automatically produce the same answer in every case. Some cases should not proceed through mediation. In others, safeguards such as separate arrival times, virtual participation, shuttle mediation, support persons or lawyer-assisted mediation may reduce risk.

Mediation should not be used to pressure someone into unsafe contact or an unfair agreement.

Step 3: Gather Your Financial Documents

Financial disclosure is essential when mediation addresses child support, spousal support, property or debt. Each spouse should provide complete and accurate information before making final decisions.

Documents may include:

• Personal income tax returns
• Notices of Assessment and Reassessment
• Recent pay statements
• Employment contracts and bonus information
• Bank and investment statements
• RRSP, TFSA and pension information
• Mortgage, line of credit and credit card statements
• Property ownership and valuation records
• Life insurance information
• Business or corporate financial statements
• Trust documents
• Records of foreign property or cryptocurrency
• Existing domestic contracts and court orders
• Ontario Form 13 or Form 13.1, where applicable

The required dates matter. For an equalization calculation, spouses may need values from the date of marriage, the valuation date and the current date.

Do not leave out an asset because its value is uncertain. Identify it and determine whether an appraisal, pension valuation or expert business valuation is needed.

Why full disclosure matters

Section 56(4) of Ontario’s Family Law Act permits a court to set aside a domestic contract in certain circumstances, including where a party failed to disclose significant assets, debts or other liabilities that existed when the agreement was made.

Incomplete disclosure can also:

• Delay the mediation
• Produce an incorrect support or property calculation
• Increase professional fees
• Damage trust and credibility
• Lead to future litigation about the agreement

Disclosure should be treated as a foundation of the settlement, not a formality.

Step 4: Understand Your Financial Position

Collecting documents is only part of the preparation. You should also understand what they mean before negotiating.

Review:

• Each spouse’s income from all sources
• Regular and irregular employment compensation
• Family expenses and cash flow
• Assets and debts
• Potential equalization entitlement
• Child and spousal support ranges
• Pension and retirement assets
• Tax consequences
• Costs associated with keeping or selling the home
• Future financial needs

Complex cases may require help from an accountant, business valuator, pension specialist, financial planner or tax professional.

For example, cash, registered investments, a pension and a business interest with the same stated value may not have the same after-tax value or liquidity. A settlement should not compare assets based only on their headline numbers.

Step 5: Obtain Independent Legal Advice

The mediator is neutral. Even if the mediator is a family lawyer, that person does not act as either spouse’s lawyer and should not provide one spouse with individual legal advice against the other.

Before negotiating major terms, speak with your own Ontario family lawyer about:

• Your legal rights and obligations
• The likely range of court outcomes
• Child and spousal support
• Property division and equalization
• The matrimonial home
• Parenting arrangements
• Limitation periods
• Financial disclosure
• The strengths and risks of your position

Legal advice is particularly important before accepting a final proposal.

Independent legal advice helps demonstrate that each spouse understood the agreement and its consequences. It can reduce the risk of an unfair result or a later challenge to the agreement.

Step 6: Identify and Prioritize the Issues

Prepare a written list of everything that needs to be addressed. Divide the list into:

• Issues already resolved
• Issues requiring more information
• High-priority concerns
• Areas where compromise may be possible
• Urgent temporary arrangements
• Longer-term arrangements

For each issue, consider:

1. What outcome do I prefer?
2. Why does that outcome matter?
3. What information supports my position?
4. What alternatives could meet the same underlying need?
5. What might a court realistically decide?
6. What will happen if no agreement is reached?

This preparation helps distinguish genuine priorities from positions taken because of anger, fear or misunderstanding.

Step 7: Set the Agenda and Exchange Information

At the start of the mediation, the spouses and mediator identify:

• The issues to be addressed
• The order in which they will be discussed
• Outstanding financial disclosure
• Any expert reports or valuations required
• Temporary arrangements needed while mediation continues
• Who may attend the sessions
• A proposed schedule

Some issues depend on others. For example, a decision about whether one spouse can keep the matrimonial home may depend on its value, mortgage financing, equalization and support.

Resolving issues in the right order can prevent wasted time.

Step 8: Attend the Mediation Sessions

Mediation may take place in person or by video. Sessions may involve both spouses together or occur through shuttle mediation, where the mediator moves between separate rooms or virtual meetings.

The number and length of sessions depend on:

• The number of disputed issues
• The complexity of the finances
• Whether disclosure is complete
• The level of conflict
• Each spouse’s ability to make decisions
• Whether experts or lawyers are involved

During the sessions:

• Focus on the issue being discussed
• Ask questions when information is unclear
• Avoid agreeing to terms you do not understand
• Take breaks when needed
• Record items that require legal or financial advice
• Consider the practical effect of each proposal
• Test whether the proposed arrangement will work over time

Effective mediation is not simply about being agreeable. It requires informed, voluntary decision-making and enough time to consider important consequences.

Step 9: Review Proposed Terms Carefully

If the spouses reach common ground, the mediator may prepare:

• A mediation report
• Minutes of Settlement
• A Memorandum of Understanding
• A summary of the agreed terms
• A draft Separation Agreement, where the mediator’s professional role permits it

These documents are not interchangeable. A Memorandum of Understanding or mediation summary is not automatically a binding Separation Agreement.

Before signing anything intended to be final, each spouse should have an independent lawyer review:

• Whether the language accurately reflects the settlement
• Whether the agreement is complete
• Whether support calculations are correct
• Whether property values and debts are properly addressed
• Whether tax consequences were considered
• Whether parenting terms are clear and practical
• Whether the agreement includes an effective dispute-resolution process
• Whether further documents, transfers or court orders are required

Do not assume the mediator’s summary is ready for signature or court enforcement.

Step 10: Prepare and Sign the Separation Agreement

Under section 54 of Ontario’s Family Law Act, separated spouses may enter into an agreement dealing with their rights and obligations.

For a domestic contract to be enforceable under section 55, it must generally be:

• In writing
• Signed by both parties
• Witnessed

Each spouse should sign voluntarily after receiving independent legal advice and complete financial disclosure.

The agreement may also require implementation steps, such as:

• Transferring title to property
• Refinancing a mortgage
• Dividing pension benefits
• Transferring registered investments
• Changing insurance beneficiaries where permitted
• Starting support payments
• Completing an equalization payment
• Preparing a consent court order

Signing the agreement is not always the final administrative step.

Step 11: File or Incorporate Terms Where Appropriate

Ontario allows certain support provisions in a domestic contract to be filed with the court for enforcement. Once properly filed, support terms may generally be enforced as if they were a court order, including through the Family Responsibility Office where applicable.

Parenting provisions require different treatment. A parenting agreement is important evidence of the parents’ intentions, but parenting decisions always remain subject to the child’s best interests. Where appropriate, the parties may ask the court to include agreed parenting terms in a consent order.

Under the Divorce Act, a court may incorporate a parenting plan into a parenting or contact order unless doing so would not be in the child’s best interests.

Your lawyer can advise whether the terms should remain in a Separation Agreement, be filed for support enforcement or be incorporated into a court order.

Step 12: Apply for Divorce if Required

Reaching a mediated settlement does not legally dissolve the marriage.

One or both spouses must still apply to the court for a divorce. In most cases, a divorce may be granted after the spouses have lived separate and apart for at least one year, although the application can be started before that year has passed.

If parenting, support and property issues have already been resolved, the divorce may proceed as an uncontested or joint divorce. The court must still be satisfied that reasonable arrangements have been made for the support of any children of the marriage.

How Much Does Divorce Mediation Cost in Ontario?

There is no standard fee. The total cost can depend on:

• The mediator’s hourly rate
• Intake and screening fees
• The number and length of sessions
• Preparation and document-review time
• Whether lawyers attend
• The need for valuations or other experts
• The complexity of the agreement
• Whether court documents or consent orders are required

Some mediators charge each spouse an equal share. Others permit a different arrangement. Payment of the mediator’s fee does not determine the outcome or give one spouse greater control.

Ontario’s court-connected Family Mediation Services may offer on-site mediation without charge for limited issues and off-site mediation on a sliding-fee scale. Availability, eligibility and service limits should be confirmed with the provider serving the local court.

Mediation is frequently less expensive than contested litigation, but it should not be described as automatically cheap or fast. Poor disclosure, repeated cancellations or entrenched conflict can make the process longer and more costly.

How Long Does Divorce Mediation Take?

A relatively straightforward case may be resolved in several sessions. A case involving a business, pension, multiple properties, disputed income or complex parenting concerns may take much longer.

The timeline is affected by:

• How quickly disclosure is exchanged
• Whether asset values are agreed upon
• The number of disputed issues
• The availability of the spouses and professionals
• Whether temporary arrangements are required
• Whether each spouse obtains legal advice between sessions

A rushed settlement is not necessarily a successful one. The objective should be a complete, informed and durable agreement.

Lawyer-Assisted Mediation

Spouses may attend mediation with their lawyers. Lawyer-assisted mediation can be helpful when:

• The legal or financial issues are complex
• Court proceedings are already underway
• There is a significant difference in legal knowledge or bargaining ability
• The spouses want to complete negotiations in one scheduled day
• Drafting and legal advice are needed as offers develop
• The case is approaching a motion, conference or trial

In other cases, the spouses attend alone and consult their lawyers between sessions. The appropriate format depends on the people, the issues and the risks.

When Mediation May Not Be Appropriate

Mediation may not be appropriate where:

• A person cannot participate safely or voluntarily
• There is serious coercive control or intimidation
• Urgent protection for a spouse or child is needed
• A spouse refuses to provide financial disclosure
• Assets are being hidden, transferred or depleted
• A spouse repeatedly ignores temporary arrangements
• There is an immediate risk that a child will be removed
• A limitation period or urgent court deadline is approaching
• One spouse uses mediation only to delay the case
• A participant cannot understand or evaluate proposed terms

In some cases, mediation may proceed with safeguards. In others, lawyer-led negotiation, arbitration or court may provide a safer and more effective process.

If there is an immediate safety concern, contact emergency services or obtain legal advice about an urgent family court application. Mediation should not delay necessary protective action.

Mediation, Arbitration or Court: What Is the Difference?

Some families use mediation-arbitration, commonly called med-arb. If mediation does not resolve every issue, the arbitrator may decide the remaining issues. Ontario has specific legal requirements for family arbitration agreements, screening and independent legal advice.

Frequently Asked Questions

Is divorce mediation mandatory in Ontario?

No. Mediation is generally voluntary unless the parties have agreed to participate or a specific court-connected process requires an attendance. Lawyers must discuss appropriate family dispute resolution options with clients, but mediation is not suitable for every case.

Can a mediator grant a divorce?

No. A mediator can help spouses settle the issues arising from separation, but only a court can grant a divorce order.

Is a mediator’s agreement legally binding?

Not automatically. A mediator’s summary or Memorandum of Understanding may record the proposed settlement but is not necessarily a binding domestic contract. Final terms should be reviewed by independent lawyers and incorporated into a written, signed and witnessed Separation Agreement.

Do we need separate lawyers if we use one mediator?

Each spouse should obtain advice from a separate lawyer. The mediator must remain neutral and cannot protect both spouses’ individual legal interests. One lawyer cannot ordinarily give independent legal advice to both sides of the same separation agreement.

Can my lawyer attend mediation?

Yes. Lawyers may attend the sessions, participate in a dedicated settlement day or advise their clients between sessions. Lawyer-assisted mediation can be especially useful in complex or high-conflict cases.

Is divorce mediation confidential?

It depends on the mediation agreement and whether the process is open or closed. Closed mediation is generally confidential, but exceptions can apply to safety concerns, reporting obligations and other legal requirements.

Can mediation address parenting arrangements?

Yes. Parents can use mediation to develop a parenting plan covering schedules, decision-making, holidays, communication and future dispute resolution. Any parenting arrangement must remain consistent with the child’s best interests.

What happens if mediation fails?

The spouses may continue negotiating through lawyers, try arbitration, use med-arb or proceed in family court. Partial agreements reached during mediation may still reduce the number of unresolved issues.

Can a Separation Agreement be challenged later?

Yes, in limited circumstances. A court may set aside all or part of a domestic contract for reasons that include significant financial non-disclosure, a failure to understand the nature or consequences of the agreement, or other grounds available under contract law. Parenting and child support terms also remain subject to statutory requirements.

Can we use the same mediator if court proceedings have already started?

Yes. Mediation can take place before or during a court case. The parties should address court deadlines, temporary orders and the proper documentation of any settlement with their lawyers.
