How Much Does It Cost to Bring a Motion for Summary Judgment in Ontario?

Bringing a motion for summary judgment in Ontario typically costs between $10,000 and $30,000 CAD in legal fees. While this is a significant upfront investment, a successful motion can save your business the $50,000 to $100,000+ CAD it generally costs to take a complex corporate dispute all the way through a multi-year civil trial.

Corporate litigation can drain a company’s resources rapidly, tying up valuable capital and management focus. If your business in Hamilton, London, or Markham is locked in a commercial contract dispute, you might not need to endure a lengthy, multi-year trial. In Ontario, the Rules of Civil Procedure offer a powerful shortcut for straightforward disputes.

Under Rule 20, a motion for summary judgment allows a party to ask a judge of the Superior Court of Justice to make a final ruling based entirely on written evidence and transcripts, arguing that there is “no genuine issue requiring a trial.” This strategy is highly effective for clear-cut cases, such as an undisputed unpaid debt or a blatant breach of contract. However, drafting the extensive motion materials requires heavy legal lifting. 💼

Step-by-Step Summary Judgment Process in Ontario

A summary judgment is not a simple letter to the judge; it is essentially a “mini-trial” conducted on paper. The procedural requirements are incredibly strict, and retaining an experienced commercial law firm is generally mandatory for success. Here is how the process unfolds.

Step 1: Assess the Viability of the Motion

Before spending thousands of dollars, your lawyer must objectively evaluate your case. Summary judgment is appropriate only when the documentary evidence is so overwhelming that a judge does not need to hear live witnesses to assess credibility.

If the dispute hinges on a “he-said, she-said” verbal agreement or complex, conflicting expert opinions, the judge will likely dismiss the motion and order a full trial. Identifying the true nature of the dispute is the most critical first step. 🔍

Step 2: Draft the Notice of Motion and Affidavits

If the strategy is viable, your legal team will draft a Notice of Motion and highly detailed Sworn Affidavits. An affidavit is a written statement of facts sworn under oath by you or your corporate officers.

You must attach every relevant document-contracts, emails, invoices, and bank statements-as an exhibit to the affidavit. This creates the factual foundation that the judge will read. Drafting airtight affidavits takes dozens of billable hours, making this the most expensive phase of preparation. 📑

Step 3: Conduct Cross-Examinations on Affidavits

Once your affidavits are served, the opposing party has the legal right to cross-examine the person who swore the document. This is done out of court in a boardroom, with a certified court reporter present.

Your lawyer will also cross-examine the opposing party on their responding affidavits. The court reporter produces a written transcript of these interrogations, which is then submitted to the judge to highlight any lies, inconsistencies, or admissions made by the other side. 📜

Step 4: Draft Factums and Argue the Motion

Finally, your lawyer will draft a Factum, which is a persuasive legal essay that ties your evidence to Ontario case law, proving why you deserve to win.

Both sides will then attend a motion hearing at the local Superior Court. The lawyers will present their arguments to the judge, who will usually “reserve” their decision and issue a written ruling a few weeks later. If you win, the lawsuit is effectively over, and you receive a legally enforceable judgment. 🔑

How Much Does it Cost in Ontario?

Because a summary judgment condenses all the legal arguments of a trial into a massive document package, the upfront legal fees are heavy. Costs are driven by the volume of evidence and the hours spent conducting cross-examinations.

  • Initial Assessment & Strategy: $1,500 to $3,000 CAD.
  • Drafting Affidavits and Motion Records: $5,000 to $12,000 CAD.
  • Cross-Examinations (Lawyer time & Court Reporter fees): $3,000 to $8,000 CAD.
  • Drafting Factums and Court Attendance: $4,000 to $10,000 CAD.
Litigation PathwayEstimated Total Legal Fees (CAD)Risk Factor
Summary Judgment Motion$10,000 – $30,000+If you lose the motion, you must still pay for a full trial later, plus cost awards.
Full Civil Trial (Superior Court)$50,000 – $150,000+Massive financial drain and years of corporate distraction.

It is important to note the risk of adverse costs. In Ontario, if you bring a summary judgment motion and lose, the judge will typically order you to pay a portion of the other side’s legal fees.

How Long Does the Process Take?

While much faster than a standard trial, a summary judgment still requires patience. Gathering evidence, drafting affidavits, and scheduling cross-examinations usually takes 3 to 5 months.

Getting a date to argue the motion before a Superior Court judge depends heavily on the local courthouse backlog. In Toronto or Ottawa, you may wait an additional 4 to 8 months for a hearing date. Overall, expect the summary judgment process to take roughly 6 to 12 months from start to finish. ⌛

Frequently Asked Questions (FAQ)

What is a “Partial” Summary Judgment?

A partial summary judgment resolves only specific parts of a lawsuit. For example, a judge might rule that a breach of contract definitely occurred, leaving only the exact calculation of financial damages to be decided at a later trial.

Can I bring a summary judgment in Small Claims Court?

No. The formal Rule 20 Summary Judgment process is specific to the Superior Court of Justice. However, Small Claims Court has a simpler mechanism called a “Motion to Strike” for claims that are frivolous or legally baseless.

What happens if the judge dismisses my motion?

If the judge decides there is a genuine issue requiring live witnesses, they will dismiss your motion. The lawsuit will then proceed down the normal, lengthy path toward a full civil trial, and you may be ordered to pay the opposing party’s legal costs for the motion.

Can the other side stall the summary judgment?

Yes, opposing counsel will often try to delay the process by refusing to schedule cross-examinations or requesting extensions to file their responding materials. Your lawyer may need to seek case management intervention from a judge to keep the timeline moving.

Is a summary judgment decision legally final?

Yes, it has the exact same legal weight as a verdict reached after a full trial. However, like any final ruling in Ontario, the losing party has the right to file an appeal with the Ontario Court of Appeal if they believe the judge made a specific error in applying the law.
