I used an agent, but I didn't tell anything to them. I only disclosed to the upfront doctor. In the part of the form where they ask if I'll need medical attention, I put "all the details were disclosed in the upfrom exams" when the agency asked to put more details I told them I had already given all information to the doctor. I don't need to pay medication, as refugee the gov pays it. Also if you don't have insurance you can get for free if you're in Ontario from some clinics for uninsured people. No private insurance here covers this medication as far as I know since they cost 1080$/month.
