Public Health Insurance Available: No
International students in Ontario are not eligible for the provincial Ontario Health Insurance Plan (OHIP). For this reason, all higher education institutions in Ontario offer health insurance plans that are available to international students.
Public universities generally offer health insurance through the University Health Insurance Plan (UHIP), while colleges and other private institutions may present options from other providers.
Health insurance plans offered to international students through education institutions are not free. The costs are usually added to a student’s university fees.

Do you have family members who will be moving with you to Canada? If they are eligible dependants, you must buy them UHIP coverage if they will be living with you in Ontario. Only dependants with an exemption can opt out of UHIP.
Eligible dependants include:
The legal or common-law spouse who is living with the eligible student or employee, where the common-law relationship has existed for at least 12 months.
The natural or legally adopted child, stepchild, or child for whom the eligible student or employee has been appointed legal guardian, whose primary residence is with the student or employee, is unmarried, dependent on the student or employee for support, and under age 22 (under age 25 if studying full-time at an accredited educational institution, or any age if mentally or physically disabled.
Dependants of Primary Members whose coverage under this policy terminated in the last five years are eligible for coverage under this policy while waiting for OHIP approval.
Other family members, such as your siblings or parents, aren’t eligible dependants.

Your dependants won’t be automatically enrolled. You need to enroll your eligible family members.
