Even Ontario objected to federal intrusion in health services. John Robarts, the new leader of the provincial Progressive Conservatives, represented a London, Ontario constituency that contained many of the nation’s leading insurance companies. He supported their campaign to have existing prepaid plans form the basis of a national scheme. Recognizing that not all Ontarians could afford coverage, however, his government created the Ontario Medical Services Insurance Plan (OMSIP)to provide for their needs, as well as to extend coverage for other citizens. Although NDP critics in the Ontario legislature labelled this plan “OMSIPID” and the Ontario Liberals condemned it as “Robartscare,” the program did receive support from the OMA. The combination of provincial subsidies for the poor and private insurance for those who could afford it nevertheless left many Canadians vulnerable to catastrophic costs for medical services and hence very interested in a national plan. The Hall Commission had offered an option. What would the provinces require in such a plan?
