DTC Prep

For medical practitioners

Your patient may have arrived with a document we prepared. This page sets out exactly what it is and what it is not, so you can decide how much weight to give it.

Nothing we produce is a medical opinion, and none of it is intended to lead you to a conclusion. We are not clinicians. If you read our document and disagree with it, you should say so, and we would rather you did.

Who may certify which impairments

Narrower than most patients assume. Only a medical doctor or nurse practitioner may certify all impairments.

Your fee

You may charge for completing the application or for providing information. That fee is yours and is separate from ours. The CRA indicates your patient may be able to claim it as a medical expense on line 33099 or 33199.

The digital route

Your patient completes Part A and receives a reference number, which they give to you. You complete Part B and the form submits automatically. Part A and Part B must use the same method: the CRA cannot process an application where the whole thing is not in the same format.

If your patient has not yet been to see you, they can work through our free self-check and bring you the result. It runs in their browser, we never see it unless they choose to send it, and it costs them nothing.
