Yep. I am in Vancouver right now. It is midnight here. Haha. and I am so glad to be here.
Yes, there is a very good chance that you would be able to get visa, given that your health is good.
Before flying to Canada, I had asked the doctors here to give me a prescription for 3 months along with medicine. I brought 3 months medicine with me because the MSP (government insurance in British Columbia) starts in around 3 months of applying. So, when I landed I straight away applied for MSP and got it within 3 months. And for TB they had given me a surveillance letter and I had to contact the hospital here. They gave me appointment and things are sorted with them. So, I would advise you to get admission in a really good university and would be good to go. But do your visa medical 4 months in advance of course start date.
