Taiwan's major hospitals offer adequate services to foreigners, and some doctors are able to communicate in English. Treatment of minor problems will generally not cost much, even without expat medical insurance. A simple consultation with a doctor, for example, will usually cost around C$5 to C$15.
Foreign residents possessing a valid Alien Resident Certificate for more than four months are eligible to join the National Health Insurance (NHI) program. Those who join the program contribute regular monthly premiums and are eligible for all NHI-covered benefits. The program is inexpensive and offers very broad coverage. However, it would not fully cover the costs of treating a serious medical problem. Medical bills, especially for hospital stays, can mount up very quickly.
It is strongly recommended that foreigners take out additional international medical insurance through either Taiwanese insurance companies or Canadian providers prior to arrival in Taiwan.
