Final answer:
In 1947, Premier Tommy Douglas in Saskatchewan introduced significant social policy reforms including a universal hospitalization plan, which laid the groundwork for Canada's Medicare system.
Step-by-step explanation:
In 1947, under Premier Tommy Douglas, Saskatchewan saw significant developments in social policy. Tommy Douglas, leading the Co-operative Commonwealth Federation (CCF), was instrumental in the introduction of the universal hospitalization plan, setting the foundation for modern healthcare in Canada. These reforms were part of the larger social democratic agenda that Douglas pursued, which ultimately culminated in the establishment of Canada's Medicare system in 1966.
As part of his agenda, he focused on other social welfare improvements too, including the creation of union rights, pension plans, and the first program to offer free hospital care to all citizens of Saskatchewan. These initiatives under Douglas's leadership transformed the province into a model of social welfare and set a precedent for many social policies that Canadians benefit from today.
