If you file taxes online, you should be able to receive the notice of assessment (NOA) and the tax refund within 2 weeks from the date of filing taxes. If you file by mail, tax refunds can take up to 8 weeks, and if you live outside Canada, it can take up to 16 weeks. If you have received the notice of assessment but haven’t received the tax refund, you should be able to receive the tax refund through a cheque or direct deposit within 2 weeks. You can contact Canadian Revenue Agency (CRA) after 2 weeks. The CRA does not give you a tax refund if your refund is less than $2, you owe an amount (taxes or debt) to the (federal, provincial, or territorial) government, or if a wage garnishment law applies to you.
