How to File a Plaintiff’s Claim for Unpaid Invoices in Vaughan

5 Jun 2026 3 min read No comments Local Civil Litigation & Small Claims Vaughan
💡

To recover unpaid invoices up to $35,000 CAD in Ontario, your business can file a Plaintiff’s Claim in Small Claims Court. The standard filing fee is currently $108 CAD, and you must serve the legal documents correctly to initiate the lawsuit.

Small businesses in Vaughan-from contractors in Concord to local service providers in Woodbridge-rely entirely on healthy cash flow. When a client refuses to pay a legitimate invoice after multiple requests, pursuing civil litigation may be your only realistic option to recover the funds.

In Ontario, the Small Claims Court is a branch of the Superior Court of Justice designed to handle disputes under $35,000 CAD in a more streamlined manner. 💰 Filing a lawsuit signals to the debtor that you are serious, and often prompts a settlement before you even see the inside of a courtroom.

Step-by-Step Process in Vaughan

While the Small Claims process is designed to be accessible to the public, missing a single procedural step can result in your claim being dismissed. Following these guidelines ensures your legal action is valid.

Step 1: Send a Final Demand Letter

Before involving the courts, always send a formal demand letter. 📧 Outline the exact amount owed, attach the unpaid invoices, and give a firm deadline (usually 10 to 14 days) to pay before legal action commences. This demonstrates to the judge that you tried to resolve the issue amicably.

Step 2: Draft the Plaintiff’s Claim (Form 7A)

If the deadline passes, complete Form 7A. You must clearly identify the defendant’s exact legal name (especially if they are a corporation) and summarize the dispute. Keep your explanation concise and factual, attaching your contracts, emails, and invoices as evidence.

Step 3: File the Claim with the Court

You can file your claim online through the Ontario government’s portal or in person at the local courthouse serving York Region. 💻 The clerk will review your documents, stamp them with a court seal, and assign you a unique file number.

Step 4: Serve the Defendant

You cannot simply mail the claim. The stamped Plaintiff’s Claim must be personally served to the defendant within six months of filing. Most business owners hire a process server to ensure service is done according to the strict rules of the court, followed by filing an Affidavit of Service.

How Much Does it Cost in Ontario?

Going to Small Claims Court involves initial investments, but if you win, the judge typically orders the losing party to reimburse your filing fees. 💸

Court ProcedureEstimated Cost (CAD)
Filing the Plaintiff’s Claim$108 CAD
Process Server Fees$100 to $250 CAD per defendant
Requesting a Default Judgment$89 CAD (if they fail to respond)
Setting a Trial Date$294 CAD

Many businesses choose to hire a licensed paralegal to handle the entire process. Paralegal representation for a Small Claims action typically ranges from $1,500 to $3,500 CAD depending on whether the case settles early or goes to a full trial.

How Long Does the Process Take?

Once the defendant is served, they have 20 days to file a Defence. ⌛ If they file a Defence, the court will schedule a mandatory Settlement Conference, which usually happens 3 to 6 months after filing. If the matter is not resolved at the conference, getting a final trial date in the York Region court system can take an additional 8 to 14 months.

Frequently Asked Questions (FAQ)

What if the unpaid invoice is over $35,000?

If the debt is higher than $35,000 CAD, you must either waive the excess amount to keep it in Small Claims Court, or hire a civil litigation lawyer to file a formal Statement of Claim in the Superior Court of Justice.

Is there a time limit to sue for an unpaid invoice?

Yes. Under the Ontario Limitations Act, you generally have exactly two years from the date the invoice became overdue (or the date they last acknowledged the debt) to file your lawsuit.

Can I claim interest on the unpaid invoices?

Yes. You can claim the interest rate specified in your contract. If you did not have a written contract with a specific rate, you can claim pre-judgment interest as determined by the Courts of Justice Act.

Do I have to hire a lawyer for Small Claims Court?

No, you are allowed to represent yourself or your corporation. However, utilizing a licensed paralegal or a civil litigation lawyer is highly recommended to avoid costly procedural mistakes.
