Recovering an unpaid B2B invoice in Canada moves through three stages: a formal demand, a civil claim in the province where the debtor is based, and enforcement against assets if the judgment still goes unpaid. The sequence only pays for itself if the debtor has something to seize at the end.
This route applies when a Canadian business or a business trading in Canada owes you money under a commercial contract and disputes nothing except the payment date. It works whether the contract is governed by common law in most provinces or by the civil code in Quebec, provided you can show the invoice, the delivery or service, and the absence of payment.
It does not apply cleanly when the debtor is already in bankruptcy or restructuring. In that case you file a claim with the insolvency estate rather than sue directly, and what happens when a Canadian debtor becomes insolvent changes the whole calculation. It also does not apply well when the debtor genuinely disputes the goods or the service delivered – that is a contract dispute, not a collections file, and it needs a different kind of preparation.
The stages below are the same in structure across provinces. What differs is the court, the forms, and how service of process is carried out on a business that may operate from more than one province.
The mechanics of filing and service differ by province, much as they differ between Canada and neighbouring markets – see how to recover an unpaid B2B invoice in the USA for the comparison most creditors ask about first.
Three things move the cost more than anything else. Whether the debtor contests the claim is the biggest one – an undisputed default judgment is comparatively fast, a contested hearing is not. The province matters too: procedure, forms and the level of court a claim of this size belongs in are set provincially, not federally, so a file involving debtors in more than one province needs separate tracking.
Time also runs against you before you file anything. The applicable limitation period is shorter than most creditors assume, and it is calculated differently depending on the province and on when the debt fell due. A claim filed after it has expired is dismissed regardless of how clear the debt is, so this is checked before any other step, not after.
The third driver is whether the debtor has recoverable assets in Canada at all. If the business has wound down or moved its operations, enforcement can stall even after a clean judgment, and the practical route may shift toward enforcing a foreign judgment against a Canadian debtor instead of starting fresh proceedings locally.
The decision point sits right after the formal demand. If the debtor pays or proposes a workable schedule, the file closes there at the lowest cost. If it goes silent or disputes without substance, you weigh the size of the debt against the cost of a contested claim before filing anything with a court.
At this stage it is worth confirming the actual mechanics for your file rather than assuming they match a domestic claim you have run before. Cross-border debt recovery services for Canadian debtors exist precisely because the province, the entity structure and the asset location change what "filing a claim" actually involves for an out-of-country creditor.
Stop, or at least pause, when any of the following is true. The debtor has no traceable assets in Canada and none abroad you can reach – a judgment against an empty shell recovers nothing. The cost of a contested hearing, once you price in the time your own staff will spend on it, is close to or above the invoice value. The debtor has entered formal insolvency proceedings, in which case a fresh civil claim is the wrong tool and a proof of claim in the estate is the right one.
Before committing to any of these routes, check the limitation period before you file – a claim that is time-barred is not worth the cost of preparing it, however strong the underlying debt.
Yes. Being based outside Canada does not stop you filing a claim against a Canadian debtor. You still need a Canadian address for service or a local process, and the court will apply the usual rules on jurisdiction based on where the debtor operates.
Small claims courts handle many commercial disputes, but each province sets its own ceiling for what counts as a small claim and its own procedure. Above that ceiling, the claim goes to a higher court with different forms and different timelines.
If the debtor is properly served and does not respond within the time the court allows, you can typically apply for a default judgment. That judgment still has to be enforced against actual assets before it turns into payment.
The cost of choosing the wrong route in Canada shows up only after you have already filed, once a contested hearing or a stalled enforcement has absorbed the time you meant to spend closing the invoice. Checking the province, the limitation period and the debtor's assets before you commit is what keeps this decision reversible for as long as possible.
