Wage and bank garnishment after a Small Claims Court judgment

Scope of this guide
This guide covers ordinary post-judgment garnishment by a private creditor under the Wages Act and Rule 20.08. It does not automate family-support enforcement, federal Crown or public-servant garnishment, or Canadian Armed Forces regimes, and it is not legal advice.

What garnishment is

Garnishment is a post-judgment enforcement step. The creditor obtains a notice of garnishment from the court and serves it on a third party (a garnishee) who owes or holds money for the debtor - typically an employer or a bank. The garnishee is then required to pay the attachable portion into court.

Wages: the ordinary 20% rule

Under section 7 of the Wages Act, $80% of a debtor's net wages is generally exempt from garnishment, leaving up to $20% attachable per pay period. A judge may increase or decrease the statutory exemption on a motion by either party where the facts justify it.

Support enforcement is different

Where the underlying obligation is a family-support order, different exemption rules apply and enforcement typically runs through the Family Responsibility Office. This site's estimator is not built for support enforcement and should not be used for that purpose.

Joint debts and Rule 20.08

Rule 20.08 addresses debts jointly payable to the debtor and another person, such as a joint bank account. The default mathematical assumption is that one-half of the joint amount - $50% - is attachable. That default is not a legal determination of ownership. The co-owner or the debtor can dispute the share, and the court can order a greater or lesser proportion based on evidence.

Protected funds

Certain funds are protected in whole or in part from garnishment - for example, specific pension and social benefit payments. If a garnishee statement suggests protected funds are in the account, the debtor should raise that issue on the record.

Ownership, set-off, and competing creditors

Garnishing a bank account does not resolve who legally owns the money. Banks may also assert set-off rights for amounts the debtor owes them, and other creditors may have prior notices of garnishment or priority under statute. Any of these can reduce or eliminate what the creditor recovers.

Worked example

Facts. A judgment creditor obtains a notice of garnishment addressed to the debtor's employer. The debtor's net wages for a pay period are $2,000.

Ordinary Wages Act calculation. $20% × $2,000 = $400 potentially attachable per pay period, subject to any court order increasing or decreasing the statutory exemption. The remaining $1,600 is exempt.

Joint bank account. If the debtor holds an account jointly with another person and $10,000 is on deposit, Rule 20.08 uses a default assumption that one-half - $5,000 - is attachable, subject to evidence of actual ownership and to any court order granting a greater or lesser share.
