changing income tax returns
1/19/2019 at 12:42 AM
You can change a return from up to 10 years ago.
The easiest way would be to register an online "My Account" with the CRA. Once registered you can do numerous things, including setting up direct deposit for government cheques, checking contribution room for RRSPs and TFSA, AND making changes to past filed income taxes by simply changing the info on the specific line on each tax return.
In the case of Westman Cable (a cooperative) if the service was for personal use, you can claim the income tax they paid on you behalf.
