Yes, it is. You should receive it within 2 to 8 weeks of filing your taxes if you reside in Canada, and in up to 16 weeks if you reside outside of Canada. Sometimes, it can pop up at an odd time during the year – this is likely due to the CRA reassessing your previous years’ taxes and realizing that you were owed some money. In these cases, you should find a Notice of Reassessment on My Account. Keep in mind that CRA can reassess your taxes for up to 3 years after you filed them.
