Does that medical expense qualify? Well, it depends...

It depends on what type of practitioner you saw, and where you saw them, as well as what they did for you. If it was cosmetic, then no, you don't get to claim it. If it was a form or report, yes, you can claim it, but the practitioner will have to charge GST/HST on their service per the last federal budget (2013)...
There is a list on the CRA website that CRA puts a disclaimer on, as it may not be completely accurate or up to date because the provinces control who is licensed. CRA pays a third party for this list and were very reluctant to even post it when our committee asked them to provide disclosure. You'll find more about this topic on this webpage and the list is found under the Definitions heading
