scylla is right. No regular visitors to Canada are eligible for the government insurance coverage and will have to pay for all necessary medical services, unless you have a private insurance policy.
As for the private insurance, you basically have two options. You can either purchase travel insurance in your country of citizenship/permanent residence or buy Visitors to Canada insurance from a Canadian insurance provider. Benefits wise, travel insurance package may seem to be more comprehensive, yet there are a lot more conditions to be met in order to get covered, limitations and exclusions compared to Visitors to Canada insurance. A Canadian insurance policy for tourists would be much easier to use if you require urgent medical assistance within Canada.
