How to Change Your Canadian Income Tax Return

If you have corrections, received some tax information late, or just remembered something to add, you can change your Canadian income tax return online or by mail. The Canada Revenue Agency asks you to wait until you receive your Notice of Assessment before you file changes though, so things don't get confused. After you send in your changes, it will take about eight weeks for the Canada Revenue Agency to make an adjustment and mail you a Notice of Reassessment.
