The former Portage la Prairie Indian Residential School

At the Portage la Prairie Indian Residential School in Manitoba, built in 1914–1915 and open until 1975, Indigenous children endured abuse, severe discipline, punishment for speaking their languages and isolation from their families. Operated by the Presbyterian and United Churches for the federal government, it was part of a policy the Truth and Reconciliation Commission called cultural genocide; Long Plain First Nation took ownership in 1981 and has made it a place of commemoration and resilience.

CA-K331History

Vancouver’s Chinatown

Vancouver’s Chinatown, one of the oldest and largest in Canada, developed as a self-segregated enclave partly because of racial hostility elsewhere in the city before the Second World War, and reflects the contributions and struggles of Chinese Canadians. It is known for a distinctive “recessed balcony” architecture that blends Chinese regional styles with western building methods.

CA-K330History

Nazrey AME Church, Amherstburg

In 1848, refugees from American slavery built the Nazrey African Methodist Episcopal Church by hand to serve Amherstburg’s growing Black community. The stone chapel is perhaps the building type most representative of Underground Railroad communities, and it is associated with Bishop Willis Nazrey, first leader of the British Methodist Episcopal Church, a wholly Canadian denomination founded by Underground Railroad refugees.

The former Shingwauk Indian Residential School

The Shingwauk Indian Residential School in Sault Ste. Marie, Ontario, opened by the Anglican Church in 1875 and closed in 1970, was part of the residential school system that sought to assimilate Indigenous children by separating them from their families, cultures and languages. Named for Chief Shingwaukonse, whose vision of education was lost, it was a Shingwauk school “in name only”; its main building, Shingwauk Hall, is one of the few remaining residential school buildings in Canada.

The exclusion of Chinese immigrants, 1923–1947

The Chinese Immigration Act (Chinese Exclusion Act), which took effect on 1 July 1923, imposed discriminatory restrictions on Chinese immigration and replaced the head tax.

Adams George Archibald (1814–1892), first lieutenant-governor of Manitoba and the North-West Territories (1870–1872), was charged with administering the Manitoba Act’s guarantee of Métis land rights, which proved difficult amid settler encroachment and while Canadian militia subjected Métis people to a “reign of terror.” In 1871 he represented the Crown in negotiating Treaties 1 and 2, but several promises he made were not written into the treaties.

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.
