You sued and won in another country, but the person or company that owes you money has assets sitting in Ontario. A foreign judgment on its own does not let you walk into an Ontario bank and seize funds — you first need Ontario's courts to recognize it. The good news is that Ontario law has long-established, workable routes for doing exactly that, though the process is not automatic.

This article explains, in general terms, how a foreign judgment can become enforceable against assets in Ontario.

Why You Cannot Just "Use" a Foreign Judgment Directly

A judgment is an order of a specific court, backed by that court's own enforcement authority. A judgment from a court outside Canada has no automatic legal force in Ontario — Ontario's sheriffs, banks, and enforcement processes do not act on a foreign court's order by itself. What a creditor generally needs is for an Ontario court to recognize the foreign judgment, after which it can be enforced here much like a judgment obtained locally.

The General Approach: Recognition Through Ontario Courts

Ontario courts have long applied general principles allowing recognition of judgments from other countries, based on considerations such as:

Some countries and jurisdictions have specific reciprocal arrangements or statutory frameworks with Canadian provinces that can streamline recognition; others do not, in which case a creditor typically relies on a general common-law action to enforce the judgment. Which route applies depends on where the original judgment came from, and this is a detail worth confirming with a lawyer rather than assuming.

What the Process Generally Looks Like

  1. Gather the foreign judgment and supporting court records. You will need a certified or properly authenticated copy of the judgment, along with documentation showing it is final.
  2. Assess the jurisdictional and fairness requirements. Before investing in the process, it is worth evaluating whether the foreign proceeding is likely to satisfy Ontario's recognition principles — a judgment obtained without proper notice to the defendant, for instance, faces real risk of being refused recognition.
  3. Start a proceeding in the Ontario Superior Court of Justice. Depending on the circumstances and the originating jurisdiction, this may take the form of an action or an application seeking recognition and enforcement of the foreign judgment.
  4. Address any defences the debtor raises. A debtor can contest recognition on the grounds above — lack of proper jurisdiction in the original court, fraud, unfairness in the original proceeding, or public policy — so the process is not always a formality, especially where the debtor is well-resourced.
  5. Obtain an Ontario order recognizing (or converting) the judgment. Once recognized, the amount owed generally becomes enforceable in Ontario using the same tools available for any other local judgment.
  6. Proceed with standard Ontario enforcement. Garnishment, a writ of seizure and sale, and examination of the debtor about their assets all become available once the judgment is recognized here.

Common Complications

Frequently asked questions

Does every foreign judgment qualify for recognition in Ontario?

No. Ontario courts look at factors like whether the original court had a proper jurisdictional basis, whether the judgment is final and monetary, and whether recognizing it would be fundamentally unfair or against public policy. Not every foreign judgment will meet these requirements.

Can a debtor re-argue the merits of the original case in Ontario?

Generally, no — Ontario courts do not usually re-decide who was right on the underlying dispute. The debtor's defences to recognition are narrower, focused on things like jurisdiction, fraud, or fairness of the original process, not re-litigating the facts.

Is the process different depending on which country the judgment came from?

Yes. Some jurisdictions have specific reciprocal arrangements with Canadian provinces that can simplify the process; others do not, meaning a general common-law recognition action is the likely route. Confirming which applies to your situation is an important early step.

How long do I have to try to enforce a foreign judgment in Ontario?

Ontario's general limitation rules can apply to when you must start a proceeding to recognize a foreign judgment, and the applicable period can depend on the type of judgment and when it was obtained. Don't assume you have unlimited time — get this confirmed early rather than waiting.
