hi there, this is a strict medical condition you are referring to and you have to provide every detail of your medical situation that consists of your current doctors clearance and your medical checkup for visa. and further more you have to create a strong SOP stating your medical conditions before and after visiting Canada. Now its all sheer luck whether you receive approval or rejection, you can see some members of this forum are getting rejections for no reason or the reason are not proper, so decision is in officers hand, but if the above conditions are fulfilled then I dont think there is any chances of rejection, and I would also like to share that visa officers nowadays dont check much in SDS applications, they only check medical, biometrics, and eligiblity as SDS students dont have to show any financial documents, that is why all say SDS applications are a quick reply, but I wonder what is happening around is not in favor of SDS students. I will also take this case to my team and if I found any more information regarding your case, I will surely update you.
