As per the Canada Revenue Agency (CRA) How you file your return can affect when you get your refund. The CRA's goal is to send you a Notice of Assessment, as well as any refund, within the following timelines: If received online - 2 weeks If paper return posted - 8 weeks Non-resident returns - 16 weeks These timelines apply only to returns that are received on or before the due date. The CRA may take longer to process your return if it is selected for a more detailed review.
You can verify and track the status and refund on your CRA MyAccount.
