MIlo phoned us lots and helped us understand how this worked. Really happy with first cheque and Milo phoned again to say we could go back farther than 3 years. Milo phone a few times and we told him our DR. didn’t want to do the forms anymore so send and s-mail to get our signature and looked after the problem. Got a refund again for 2 years. When we had a problem with this Milo kept in contact with us and straightened it out immediately. This sure helped out as we are seniors. But not sure why CRC wouldnt let us go back ten years.
I never would have known how to go about getting this refund, and the people I dealt with were very friendly and easy to talk to
