While consumer debts are strictly regulated, B2B commercial debt collection in Ontario still has legal limits. If an agency engages in severe harassment, threatens employees, or deliberately interferes with your daily operations or vendor relationships, your business can sue them in the Superior Court of Justice for the tort of intentional interference with economic relations or harassment.
Managing cash flow and resolving outstanding invoices is a routine part of running a business. However, when a vendor assigns a B2B debt to a commercial collection agency, things can sometimes turn aggressive. As of 2026, some debt buyers and commercial agencies cross the line from standard collection practices into outright corporate harassment. Whether your business is a construction firm in Hamilton, a restaurant in Toronto, or a manufacturer in London, you do not have to tolerate illegal threats or severe disruptions to your operations.
Ontario’s Collection and Debt Settlement Services Act (CDSSA) heavily regulates consumer debt, but corporate debt collection is entirely excluded from its scope. Under Section 19.7 of R.R.O. 1990, Regulation 74, the CDSSA does not apply to debts owed by corporations. However, if the business debtor is an individual—such as a sole proprietor, a partner in a partnership, or an individual guarantor of a commercial loan—the CDSSA still applies in full, with no relaxed standards or leeway. For corporate debtors, collection practices are governed strictly by contracts and common-law torts, which still prohibit harassment, extortion, and tortious interference. If your business is under siege by aggressive collectors, we highly recommend consulting a commercial litigation lawyer from our Ontario directory to launch a robust defence.
Step-by-Step Process: Defending Against Illegal B2B Collections
Taking legal action against a rogue commercial collection agency requires careful documentation. Here is how corporate litigation lawyers typically handle aggressive debt collectors in Ontario. 📍
Step 1: Document the Harassment and Interference
Evidence is the foundation of your defence and potential lawsuit. You must carefully log every interaction with the collection agency.
Keep a detailed record of phone calls, including the date, time, and the specific threats made. Save all emails, voicemails, and faxes. Most importantly, if the agency is contacting your clients, your suppliers, or your employees’ personal phones in an attempt to embarrass or pressure your corporation, document these instances. This forms the basis for a claim of intentional interference with economic relations.
Step 2: Send a Demand for Validation and Cease Communication
Your business has the right to dispute the validity of the commercial debt. Your lawyer will draft a formal letter demanding that the agency provide the original contracts, invoices, and proof of assignment of the debt.
Simultaneously, the lawyer can issue a formal cease communication directive, instructing the agency to direct all future correspondence exclusively to the law firm. If the agency continues to call your office lines directly after receiving this notice, it strengthens your case for corporate harassment.
Step 3: Review the Limitations Act
In Ontario, the basic limitation period to sue for an unpaid debt is two years from the date the invoice became overdue, or the date of the last payment/acknowledgment.
If the collection agency is aggressively pursuing a debt that is five years old, the debt is likely “statute-barred.” While they can legally ask for the money, they cannot successfully sue you for it. Using aggressive tactics to collect a legally unenforceable debt can be used against them in court.
Step 4: File a Civil Claim for Damages
If the agency’s actions have caused your business tangible harm—such as a supplier dropping your contract due to the agency’s interference, or significant loss of productivity due to relentless phone harassment—you can file a Statement of Claim at the Superior Court of Justice. ⚠️
Your litigation lawyer can sue the collection agency (and potentially the original creditor who hired them) for damages, seeking financial compensation for the harm caused to your business reputation and operations.
How Much Does it Cost in Ontario?
Defending your business against rogue agencies involves legal fees, but it is often necessary to protect your corporate reputation and sanity. 💰
- Initial Strategy Consultation: Meeting with a corporate litigator to review the debt and the agency’s conduct typically costs $300 to $500 CAD.
- Lawyer Cease and Desist Letter: Having a law firm assume communication and demand debt validation usually ranges from $500 to $1,200 CAD.
- Litigation Fees: If you must sue the agency or defend against their civil claim, commercial lawyers in Ontario generally charge between $350 and $750 CAD per hour.
- Court Filing: Issuing a Statement of Claim in the Superior Court of Justice costs approximately $243 CAD.
| Collection Tactic | Status in Commercial (B2B) Collections | Legal Remedy |
|---|---|---|
| Calling Daily During Business Hours | Generally Permitted (if not excessive) | Send formal letter routing calls to lawyer. |
| Contacting Your Clients/Vendors | Illegal Interference | Sue for Intentional Interference with Economic Relations. |
| Threatening Physical Harm or Seizure | Strictly Illegal (Criminal Code) | Police report and immediate injunction. |
How Long Does the Process Take?
Stopping the immediate harassment is usually fast. Once a respected law firm sends a formal representation letter, most commercial collection agencies will back down and stop calling your office within 48 to 72 hours. ⌛
If the dispute evolves into formal litigation—either you suing them for interference, or them suing your business for the commercial debt—the process slows down drastically. A commercial lawsuit in Ontario’s Superior Court of Justice typically takes 18 to 36 months to proceed through discovery, mediation, and a full trial.
Frequently Asked Questions (FAQ)
Does the Ontario CDSSA apply to B2B debts?
It depends on the legal structure of your business. Under Section 19.7 of R.R.O. 1990, Reg. 74, the CDSSA does not apply to debts owed by corporations (persons other than individuals). However, if the business debtor is an individual—such as a sole proprietor, a partner in a partnership, or an individual guarantor of a commercial loan—the CDSSA applies in full, with no exceptions or lower standards. For corporate debtors, collection is governed strictly by contracts and common law torts, which still prohibit harassment, extortion, and tortious interference.
Can a collection agency seize our business assets?
No. A collection agency has no special powers to seize your trucks, equipment, or bank accounts. To seize assets, they must first sue your business, win a judgment in court, and obtain a Writ of Seizure and Sale enforced by a local Sheriff.
Can they report commercial debt to the credit bureaus?
Yes, commercial collection agencies can report unpaid corporate debts to commercial credit bureaus like Equifax Commercial or Dun & Bradstreet, which can severely impact your business credit score and ability to secure future financing.
Can the agency owner be held personally liable?
Generally, you will sue the collection agency as a corporation. However, if an individual debt collector engages in egregious, malicious behaviour (like uttering death threats), they can be named personally in civil lawsuits or face criminal charges.
