Better prepare yourself with professional report (to avoid further information request later) indicating the medical condition of your son; indicating his disorder is controllable with
"only" certain medicines, no need for special treatment, no need for special care where the boy is self caring and provide evidence of school as he is doing fine.
Very important to visit following (Designated Medical Practitioner Handbook
Question 2 to see what the report should include):

Just commenting: Of course, the above; is only if you wish to mention the whole story to the medical doctor .As far as I believe; many people passed with dangerous or infectious diseases (this is not your case) but visa officers or medical officers may only stuck on a little innocent child (as in your case) as he "may or would" cause excessive demand to the
venerable society fund system..... forgetting in same time what they already accepted in the past of the well recognizable (Medically or Security) dangerous personals to go to Canada (for example as most fraud refugees who do not contribute a single cent to the society fund nor the country economy). This is the madness world we live in.
