What to Expect at a Trial Management Conference (TMC) in Ontario

In Ontario, a Trial Management Conference (TMC) is the final mandatory step before a family trial. You must file a detailed Trial Management Conference Brief (Form 17E), and hiring a family lawyer to prepare your witness list and trial record typically requires a legal retainer between $5,000 and $15,000 CAD.

Reaching the trial stage in an Ontario family law dispute is an incredibly serious milestone. After months or even years of stressful negotiations regarding spousal support or parenting time, a trial means a judge will finally make binding decisions for your family. However, you do not simply walk into a courtroom and start arguing.

Before the actual trial begins, whether you are at the Superior Court of Justice in Toronto, Ottawa, or Hamilton, you must attend a Trial Management Conference (TMC). 📅 This crucial meeting is not meant for settling the case, but rather for organizing the logistics of the upcoming trial. This plain English guide explains exactly how to prepare your evidence, estimate your time, and navigate the TMC process.

Step-by-Step Process for a Trial Management Conference in Ontario

The Ontario Family Law Rules strictly guide how a TMC is conducted. The judge’s primary goal is to ensure that both sides are completely ready so that the trial runs efficiently without wasting valuable court resources.

Step 1: Complete the Trial Management Conference Brief (Form 17E)

Your lawyer will help you draft a highly detailed Form 17E. This document outlines the specific legal issues that remain unresolved, such as child support arrears or property division. You must clearly state exactly what orders you are asking the trial judge to make, providing a strict roadmap for the court.

Step 2: Finalize Your Witness List

At the TMC, there are no surprises allowed. 👥 You must provide a complete, finalized list of every single witness you intend to call to the stand. This includes character witnesses for parenting time disputes, financial experts, or local Ontario police officers. You must also provide a strict time estimate for how long you will spend questioning each person.

Step 3: Update Your Financial Disclosure

If your case involves spousal support, child support, or the division of property, your financial documents must be perfectly up-to-date. You will likely need to file a newly sworn Financial Statement (Form 13 or 13.1) if your previous one is more than 30 days old, completely detailing your current income, assets, and debts in Canadian dollars.

Step 4: Create the Formal Trial Record

The applicant is generally responsible for creating and filing the Trial Record. 📚 This is a massive, carefully indexed binder containing all the original pleadings, applications, answers, and prior temporary court orders. It ensures the trial judge has all the official paperwork neatly organized before opening arguments begin.

Step 5: Attend the TMC Hearing

The TMC itself is typically a relatively short appearance before a judge. The judge will review your time estimates, confirm that all procedural steps are finished, and strictly order both parties to agree on a joint document brief. Once the judge is satisfied, your case will finally be placed on the official trial scheduling list.

How Much Does it Cost to Prepare for Trial in Ontario?

Going to trial is notoriously the most expensive part of any family law dispute in Canada.

  • Lawyer Retainers: Preparing for a TMC and a subsequent trial requires a massive amount of legal work. A law firm will typically require a trial retainer ranging from $10,000 to $30,000 CAD.
  • Court Fees: Setting a family matter down for trial at the Superior Court of Justice generally involves a formal scheduling fee of roughly $445 CAD.
  • Expert Witnesses: If you need a Chartered Business Valuator or a child psychologist to testify, they often charge between $3,000 and $10,000 CAD for their court preparation and appearance time.

How Long Does the Process Take?

Frequently Asked Questions (FAQ)

Can we still settle our case at the Trial Management Conference?

Yes, absolutely. While the main goal of the TMC is logistical planning, you can legally settle your dispute at any time before the trial begins. If both parties suddenly agree on a parenting time schedule or support amount, the TMC judge can draft a final consent order right then and there.

Can I add a new witness after the TMC is finished?

Generally, no. Ontario family courts heavily frown upon trial by ambush. If you suddenly try to add a surprise witness after the TMC, the trial judge will likely block them from testifying unless you can prove an extreme, unforeseeable emergency.

Do I have to speak during the TMC?

If you have hired a family lawyer, they will do almost all of the talking for you. The judge will address your lawyer regarding procedural deadlines and evidentiary rules. You are simply there to observe and provide quick instructions to your lawyer if a scheduling issue arises.

What happens if my ex refuses to show up to the TMC?

If a respondent completely ignores the court date without a valid medical excuse, the judge may strike their pleadings. This means you could be permitted to proceed to an uncontested trial, essentially winning your requested orders by default.
