Post-judgment interest in Ontario accrues from the date of judgment at the quarterly rate set by the Attorney General.
Post-judgment interest is simple, not compound. It is calculated per day on the outstanding judgment amount.
An Ontario judgment is valid and enforceable for 20 years. Interest continues to accrue until the judgment is paid in full.
Collect your judgment plus accrued interest through wage garnishment, bank garnishment, or a writ of seizure and sale.
