I’m presuming your concern is regarding health insurance for international students. In Canada health care is mostly provided by different provinces but they only cover basic health care. Students can apply for private health insurance, though they can apply to their universities for health insurance.
An international student is usually covered by the province or university/college health insurance. Though a student is only covered under the health insurance once the programme starts. It is advisable to get private health insurance for the few days before the programme starts and the student is already in Canada.
