I had my staff do just a bit more research on “Indigenous governing body”. I asked them to do a search on where that term also exists.
The term exists in Bill C-35, the early learning and child care in Canada act; in Bill C-23, an act respecting places, persons and events of national historic significance or national interest, archaeological resources and cultural and natural heritage; the Corrections and Conditional Release Act; Bill C-91, an act respecting indigenous languages; Bill C-92, an act respecting first nations, Inuit and Métis children, youth and families; Bill C-68, an act to amend the Fisheries Act and other acts in consequence; Bill C-69, an act to enact the Impact Assessment Act and the Canadian Energy Regulator Act, to amend the Navigation Protection Act and to make consequential amendments to other acts; and Bill C-97, an act to implement certain provisions of the budget tabled in Parliament on March 19, 2019.
I haven't looked at how these might differ from each other.
Having said that, have you been able to assess whether or not there are similarities or differences between what's in this act and what these other acts might be?
