You can easily get a copy of your notice of assessment (NOA) or reassessment
through My Account,
for the current year and the 10 previous years. You can also view a summary
of your assessments with the MyCRA mobile
app. To get your notices electronically, you can sign up for the CRA’s online
mail.
Similarly, you can get your Québec notice of assessment or reassessment (back
to 2004) through Revenu Québec’s My Account service.
Note: If you’re using the H&R Block 2023 tax software,
you’ll be able to request your notice of assessment (NOA) through the Express
NOA service from within the tax software. With this service, you’ll receive
your NOA in the tax software after you NETFILE your return.
