Ethics approval is required by the Government of Canada when conducting research involving human research participants. Each university has their own ethics application process overseen by their Research Ethics Board.
In most cases undergraduate student research specific to a class has had ethics approval completed by your instructor. That said, additional ethics may be required when choosing to work specifically with Indigenous Peoples. Always check with your instructor to make sure you have the correct research ethics approval.
Many of the Government of Canada TCPS2 research ethics regarding Research Involving the First Nations, Inuit and Métis Peoples of Canada closely align with the Research Done in a Good Way diagram highlighted in chapter two of this book.
