How to Collect an Unpaid Invoice Through Ontario Small Claims Court as a Sole Proprietor
You did the work, sent the invoice, waited, followed up, and eventually took your client to Ontario's Small Claims Court. The court agreed with you — the judgment says the client owes you money. But the judgment does not come with a cheque attached, and the client has not paid.
As a sole proprietor or freelancer, you are now in a peculiar position. The amount you are owed — typically $2,000 to $15,000 for unpaid services — is large enough to matter to your business but small enough that hiring a paralegal at $150–$250 per hour could eat a significant chunk of the recovery. You need to enforce the judgment yourself, and you need to do it without spending more than the judgment is worth.
Why Sole Proprietors Face a Different Calculus
An unpaid invoice judgment for a sole proprietor is not an abstract legal matter. It is money you already earned that is sitting in someone else's bank account. Every week it stays uncollected is a week your cash flow takes the hit.
Under CJA s. 29, representation costs awarded are generally capped at 15% of the amount claimed, unless the court finds unreasonable behavior. If the amount claimed was $5,000, that cap is $750. Court filing fees and process-server disbursements are separate from the cap and are recoverable as disbursements. A paralegal who charges $200 per hour and works five hours on your case bills $1,000 — up to $250 of representation costs may remain unrecovered, on top of the invoice that was already unpaid.
The enforcement tools themselves cost the same for everyone: $68 for an examination, $144 for a garnishment, $68 for a writ. These fees are recoverable as disbursements on top of the judgment. The difference between a sole proprietor who recovers most of the judgment and one who recovers half is knowing which tools to use and in what order.
The Enforcement Path for an Unpaid Invoice
Start With the Examination ($68)
File Form 20H (Notice of Examination) to summon the debtor — your former client — to answer questions under oath about their finances. For sole proprietors collecting on unpaid invoices, the examination often tells you one of three things:
The debtor is a business with revenue. You learn the business bank account, the volume of receivables, and whether the business pays regular supplier invoices. Bank garnishment targeted at the business account right after a deposit cycle is your best tool.
The debtor is an individual with a job. Wage garnishment captures 20% of their net pay every period. On a typical salary, a $5,000 judgment collects in eight to ten months with zero further action from you after the initial filing.
The debtor has nothing. No bank balance, no employment, no property worth seizing. This is the hardest answer, but it saves you from spending hundreds of dollars on garnishments that return nothing. A judgment does not expire for overall enforcement purposes, but individual tools have time limits: a garnishment issued more than six years after judgment requires court leave, and a writ remains active for six years and must be renewed before expiry.
If the Debtor Is a Business: Bank Garnishment ($144)
When the debtor is a company that still operates, bank garnishment is the fastest tool. File Form 20E (Notice of Garnishment) and serve it directly on the branch where the account is maintained, naming the financial institution. The notice captures funds held in the account at the time of service. Within 10 days, the garnishee must file a Garnishee's Statement (Form 20F) with the court and serve copies on the creditor and debtor. If it admits an outstanding debt, it must remit non-exempt funds to the court clerk. You must serve Form 20E on the debtor within 5 days after serving the garnishee and file Form 8A proving both services.
Timing matters. If you learned at the examination that the business receives a large payment on the 1st of each month, serve the garnishment on the 2nd. Serving it on the 28th catches the account at its lowest point.
For business debtors, you may also garnish debts owed to the debtor by third parties. If the debtor's client owes the debtor $8,000 on a receivable, you can serve a garnishment on that client, intercepting the payment before it reaches the debtor. This requires knowing who the debtor's clients are — which is exactly what the examination hearing is for.
If the Debtor Is an Individual: Wage Garnishment ($144)
Wage garnishment is the most reliable enforcement tool for debtor-employees. The employer deducts 20% of the debtor's net wages every pay period and sends it to the court clerk. The clerk distributes the funds to you. The debtor cannot stop it without paying the judgment or getting a court order varying the terms.
The Wages Act sets the 80% exemption — the debtor keeps 80% of net pay to live on, and you get 20%. On net monthly pay of $3,500, you collect $700 per month. A $7,000 unpaid invoice (the original amount plus postjudgment interest at 4%) takes about 10 months to collect.
Serve the garnishment on the employer's payroll department at the correct mailing address — the one the debtor gave under oath at the examination. If the debtor changes jobs, you file a new garnishment on the new employer.
The Long Game: Writ Against Land ($68 + $100 Sheriff's Filing Fee)
If the debtor owns real property, a Writ of Seizure and Sale of Land (Form 20D) can bind the title until the property is sold or refinanced. The Sheriff registers the writ electronically on the parcel register. When the property is sold or refinanced, your judgment must be satisfied before the debtor walks away with proceeds.
This does not produce fast cash, but it is long-term protection ($68 court fee plus a $100 filing fee paid to the local Sheriff's Enforcement Office) and it prevents the debtor from selling or refinancing the property without clearing the judgment debt.
Real Cost Math for Common Scenarios
$3,000 invoice, debtor employed:
- Examination: $68
- Wage garnishment: $144
- Total enforcement cost: $212
- Recovery timeline: ~5 months at $600/month garnished wages
- The $212 in court fees is recoverable as disbursements on top of the judgment
$8,000 invoice, debtor is a business with bank account:
- Examination: $68
- Bank garnishment: $144
- Total enforcement cost: $212
- Recovery timeline: depends on account balance at service — potentially one garnishment
- The $212 in court fees is recoverable as disbursements on top of the judgment
$5,000 invoice, debtor has no wages or bank balance but owns a house:
- Examination: $68
- Writ against land: $68 court fee + $100 Sheriff's filing fee
- Total initial outlay: $236, plus any further execution disbursements
- Recovery timeline: whenever the debtor sells or refinances
- Court fees are recoverable as disbursements on top of the judgment if collected

Who This Is For
- Sole proprietors, freelancers, and contractors who won a Small Claims Court judgment on an unpaid invoice
- Small business owners whose staff need a step-by-step reference for enforcement filings
- Anyone whose unpaid invoice judgment is too small to justify hiring a paralegal for the whole process
- Creditors who want to understand their enforcement options before choosing between self-help and professional representation
Who This Is NOT For
- Creditors who have not yet filed a claim — the Ontario Small Claims Filing Guide covers pre-judgment procedure
- Anyone whose debtor has filed for bankruptcy or a consumer proposal
- Disputes over work quality or contract terms that are still being litigated
Tradeoffs
Self-enforcement takes your time. A sole proprietor's time is not free — hours spent at the courthouse or on the portal are hours not spent on billable work. The question is whether the paralegal's fee saves you enough time to justify the cost. On a $3,000 judgment, spending $500–$1,000 on a paralegal to save yourself five hours of work means you are valuing your time at $100–$200 per hour for that enforcement work. If your billable rate is lower, do it yourself. If your billable rate is higher and you have clients waiting, the paralegal may be the rational choice.
For most sole proprietors chasing a single unpaid invoice, the examination and one garnishment take a total of three to four hours of active work (form preparation, filing, service). The Ontario Judgment Enforcement Guide compresses the learning curve so those hours are spent executing, not researching.
Frequently Asked Questions
Can I enforce a judgment against a corporation that has closed?
If the debtor corporation has been dissolved, enforcement options narrow significantly. A judgment against the corporation does not automatically make its directors personally liable; any separate claim against them requires legal advice. If the corporation simply stopped operating but has not been formally dissolved, its assets (bank accounts, receivables, equipment) may still be garnishable or seizable.
What if my former client disputes the judgment amount?
Once the judgment is final (appeal period expired, no appeal filed), the amount is settled. The debtor cannot re-argue the merits at the enforcement stage. The only numbers that change are postjudgment interest (accruing daily at 4%) and credits for any payments already made.
Should I add late-payment interest from my contract on top of postjudgment interest?
Postjudgment interest is governed by CJA s. 129. Any prejudgment interest the court awarded is already part of the judgment amount. Your enforcement calculations use the postjudgment rate published by the Attorney General.
Can I report the debtor to a credit bureau?
Do not assume a Small Claims Court judgment will automatically appear on Equifax or TransUnion, or rely on credit reporting as an enforcement tool. If credit reporting matters to your plan, confirm the process directly with the credit bureaus.
