What is it?
A Notice of Assessment is completed by the Canada Revenue Agency after you file your taxes. Your NOA will show you the date your return was assessed and whether you have a refund, amount owing, or a zero balance.
If there are any changes to your tax return after it was already submitted, they will also issue a Notice of Reassessment.
Where can I find it?
The assessment will be mailed to you by the Canada Revenue Agency after they have assessed your tax return.
You can also login to 'My Account' through the Canada Revenue Agency website to access an online copy. Your NOA can be found under the "tax returns" tab
