I don't think there are inconsistencies between those numbers. I have personally seen 715 cases of disallowance. I know, of course, that I have by no means seen every disallowance there has been for people with diabetes in the last six months. I have statistics that are coming from groups that treat or support thousands of patients trying to access the disability tax credit. That's where “thousands” comes from.
For the 715 cases, I'm afraid I can't provide you with a breakdown of exactly what proportion had previously qualified for the disability tax credit. However, based on an online poll of a group that represents 1,500 people who have been seeking the DTC and RDSP for a number of different conditions, I would say that a third to one-half of the people who have been disallowed in the past six months had previously been approved for the disability tax credit. It's clear that it is affecting both new applicants and people who are reapplying.
