Students planning to study in Canada should research the availability of insurance in their intended province of study. International students in Canada are required to obtain health insurance for the duration of their stay in Canada. Certain provinces offer provincial health coverage to certain international students, either for free or for a premium. In these cases, international students are usually required to apply to the province. However, your covereage starts after 3 months till then you need to get private insurance from the day you arrive.
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 heir universities for health insurance.
An international student is susually 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.
