various denominations – about 60% by Roman Catholics, and 30% by the Anglican Church of Canada and the United Church of Canada, along with its pre-1925 predecessors, Presbyterian, Congregationalist and Methodist churches. The attempt to force assimilation involved punishing children for speaking their own languages or practicing their own faiths, leading to allegations in the 20th century of cultural genocide and ethnocide. There was widespread physical and sexual abuse. Overcrowding, poor sanitation, and a lack of medical care led to high rates of tuberculosis, and death rates of up to 69%. Details of the mistreatment of students had been published numerous times throughout the 20th century, but following the closure of the schools in the 1960s, the work of indigenous activists and historians led to a change in the public perception of the residential school system, as well as official government apologies, and a (controversial) legal settlement. Colonization had a significant impact on First Nations diet and health. According to the historian Mary-Ellen Kelm, "inadequate reserve allocations, restrictions on the food fishery, overhunting, and over-trapping" alienated First Nations from their traditional way of life, which undermined their physical, mental, emotional, and spiritual health. 20th century As Canadian ideas of progress evolved around the start of the 20th century, the federal Indian policy was directed at removing Indigenous people from their communal lands and encouraging assimilation. Amendments to the Indian Act in 1905 and 1911 made it easier for the government to expropriate reserve lands from First Nations. The government sold nearly half of the Blackfoot reserve in Alberta to settlers. When the Kainai (Blood) Nation refused to accept the sale of their lands in 1916 and 1917, the Department of Indian Affairs held back funding necessary for farming until they relented. In British Columbia, the McKenna–McBride Royal Commission was created in 1912 to settle disputes over reserve lands in the province. The claims of Indigenous people were ignored, and the commission allocated new, less valuable lands (reserves) for First Nations. Those nations who managed to maintain their ownership of good lands often farmed successfully. Indigenous people living near the Cowichan and Fraser rivers, and those from Saskatchewan managed to produce good harvests. Since 1881, those First Nations people living in the prairie provinces required permits from Indian Agents to sell any of their produce. Later the government created a pass system in the old Northwest Territories that required indigenous people
