As for Ontario, Quebec, BC, New Brunswick you also have to buy Canadian Private Medical Insurance Plan for the first 90 days in Canada. The name of the plan is Visitors to Canada Single Trip Medical Insurance.You should choose the coverage amount (varys from $25,000 to $200,000). I suggest you to buy as much as you can to avoid unreasonable financial risk. If you want to decrease the cost , you can increase deductible amount. Good luck and welcome to Canada.
