Per the CRA; You can request a change to your tax return by amending specific line(s) of your return.
You must wait until you have received your Notice of Assessment before submitting any adjustment requests. This is important for a couple of reasons. First, an early adjustment request may lead to unnecessary delays in processing time for both the original return and the adjustment. Secondly, CRA may adjust your original return for you. For example, if you’ve forgotten to include unused tuition to your return, CRA has those figures and may add the amounts to your return directly.
