Displaced persons arrive after the Second World War

After the Second World War, nearly 187,000 people fled devastated Europe for Canada, including Holocaust survivors, former prisoners of war and thousands unable or unwilling to return home; most arrived by ship between 1947 and 1952. Many first worked as labourers despite professional training, and their arrival strengthened calls to recognize Canada’s growing cultural diversity.

The Saskatchewan doctors’ strike of 1962

When Saskatchewan’s Medical Care Insurance Act took effect on 1 July 1962, most of the province’s doctors went on strike for 23 days. Perhaps the most significant Canadian doctors’ strike of the 20th century, it exemplified conflicts in the development of medicare between state intervention and physicians’ independence, and between doctors as entrepreneurs and patients’ right to care regardless of income.
