Garnishment is, at its core, a way of reaching money that a third party owes to the judgment debtor rather than money the debtor is holding directly. A bank is a common and often attractive target for this, because most people and businesses keep at least some operating cash on deposit somewhere. But "the bank owes the debtor money" and "you can actually collect it" are two different things, and the gap between them is almost always information.
How bank account garnishment works
In broad terms, a judgment creditor who wants to garnish a bank account asks the court to issue a garnishment order directed at the financial institution the debtor uses. The bank, once properly served, becomes legally required to hold back and eventually remit funds it is holding for the debtor, up to the amount owed. The bank isn't a wrongdoer in any of this — it's simply the third party positioned between the creditor and money that technically belongs to the debtor while it sits in that account.
The Notice of Garnishment
The mechanism generally used is a Notice of Garnishment, issued through the court process and served on the financial institution. Once served, the institution typically has to search for accounts held in the debtor's name and, if it finds any, freeze the available balance rather than allowing the debtor to withdraw or transfer it. After a waiting period built into the process, and assuming no valid dispute is raised, the frozen funds are generally directed toward satisfying the judgment. The exact mechanics and timelines can be technical, and getting the notice served on the right institution and the right branch matters a great deal to whether it actually works.
A one-time seizure, not an ongoing deduction
It's worth being clear-eyed about what bank garnishment does and doesn't do, because people often assume it behaves like wage garnishment. Wage garnishment is generally an ongoing arrangement — a portion of each paycheque is redirected until the judgment is satisfied or the arrangement ends. A bank account garnishment is typically closer to a single snapshot: it captures whatever funds happen to be sitting in the account at the moment the notice takes effect, and nothing more automatically follows after that. If the account is nearly empty that day, the result may be disappointing even though the process itself worked exactly as intended.
The practical challenge: knowing which bank
The single biggest obstacle to garnishing a bank account isn't the legal process — it's simply not knowing where the debtor banks. Judgment creditors are rarely handed this information voluntarily, and without it, a garnishment notice has nowhere useful to go. This is precisely why a judgment debtor examination is so often recommended as an early step in enforcement: it's a formal, court-supervised opportunity to ask the debtor directly about their banking relationships, under oath, before spending time and filing fees guessing. Some creditors also learn this information informally — from a cheque, an e-transfer confirmation, or a business's own invoicing history — but when that information isn't already on hand, an examination is usually the more reliable route.
Exemptions and limits that can apply
Not every dollar sitting in an account is necessarily fair game. Certain funds can be treated differently depending on their source or purpose — for example, some government benefit payments and specific protected categories of income may be exempt or treated with added care, and a debtor who believes exempt funds have been improperly caught up in a garnishment generally has an opportunity to raise that with the court. Because these exemptions and their boundaries are technical and fact-dependent, anyone relying on a precise answer for a specific account or specific funds should get a professional opinion rather than assume either the best or worst case.
Where this fits among enforcement tools
Bank garnishment is one option among several, not a stand-alone solution. It sits alongside wage garnishment and a writ of seizure and sale registered against personal or real property as the main tools available to an Ontario judgment creditor. Which one makes the most sense — or whether more than one is worth pursuing — usually depends on what's actually known about the debtor's circumstances, which loops back to why an examination early in the process tends to save time and cost later. See judgment enforcement for the fuller comparison of how these mechanisms fit together.
Frequently asked questions
Do I need to know exactly which branch the debtor uses?
Generally you need to identify the financial institution itself; the notice is typically served on the institution's head office or a designated branch, which is then responsible for locating accounts held there in the debtor's name.
Will garnishing a bank account get me the full amount of my judgment?
Not necessarily. It typically captures only whatever funds are available in the account at the time the notice is processed, which may be far less than the outstanding balance, or nothing at all.
Can I garnish the same bank account more than once?
In principle a creditor can serve a fresh notice again later, though repeating the process has its own costs and paperwork, and there's no guarantee funds will be there the next time either.
Is a bank account always the best target for enforcement?
Not always — it depends on the debtor's circumstances. For some debtors, ongoing wage garnishment or a writ against property may be more effective, which is part of why a debtor examination is often useful before choosing.
