You have to be mindful of the Province you will be going to as a student. Not all provinces' health insurance are the same, hence not all provinces' health insurance will cover for HIV medication.
British Columbia, Alberta, Northwest Territories, Nunavut, and Prince Edward Island offer universal coverage of antiretrovirals for all of their residents living with HIV. These are the province and territories you want to choose. New Brunswick has waived co-pay collection so if you study there you can also get your meds for free.
If you will choose Toronto (Ontario) you will have to pay for your medicines. Unless you qualify for Trillium Benefit (which covers only a couple of 2 in 2 HIV drugs Dovato and Juluca)., Though if your regimen in Philippines is 3 in 1 like Lamivudine, Tenifovir, Efavirenz, your doctor may not allow you to take Dovato or Juluca. So you will have to co-pay your meds if you are in Ontario
