Which Canadian prime minister is known for establishing a national program for social welfare?

The choice of Pierre Elliott Trudeau as the prime minister known for establishing a national program for social welfare is well-founded, primarily due to his significant contributions to social policy during his time in office. Trudeau served as prime minister from 1968 to 1979 and then again from 1980 to 1984. His government introduced major reforms and initiatives aimed at improving social welfare across Canada.

One of Trudeau's key achievements was the creation of the Canada Health Act in 1984, which established a framework for universal health care to ensure that all Canadians had access to medical services regardless of their financial situation. Additionally, Trudeau’s administration was deeply involved in developing programs that supported pension schemes, unemployment insurance, and education funding, contributing to a more robust social safety net.

Trudeau's vision for a more compassionate Canada led to policies that sought to reduce poverty and improve living standards, making significant strides toward a comprehensive social welfare system that resonated with his liberal ideals. Other prime ministers mentioned had different focuses or priorities during their terms, which did not emphasize the establishment of such a national social welfare program to the same extent as Trudeau's initiatives.
