Final answer:
Some informative sources to understand Indigenous access to emergency care in Canada include the Truth and Reconciliation Commission of Canada's 'Calls to Action', a BBC News article on residential school graves, and 'On All Frontiers: Four Centuries of Canadian Nursing'. The appointment of the first Indigenous governor-general is another significant development.
Step-by-step explanation:
When researching the access to emergency care services for Indigenous people in Canada, the Truth and Reconciliation Commission of Canada provides valuable insights. Its 2015 report, including the 'Calls to Action', which can be found on its official website, specifically calls for improvements in health services for Indigenous communities. Another pertinent source is the BBC News article detailing the discovery of 751 unmarked graves at a residential school, highlighting the ongoing legacy of cultural trauma and its impact on Indigenous health outcomes. The book 'On All Frontiers: Four Centuries of Canadian Nursing' may also offer historical context on how healthcare has been delivered to Indigenous populations. Additionally, the appointment of Mary Simon as the first Indigenous governor-general, as reported by NBC News, may signal a new chapter in addressing Indigenous issues, including healthcare disparities.
