Several commenters have stated that the author is a part of the "FN industry" because he believes in consent over the lesser standard of consult.  That is incorrect.  He states:

"The UNDRIP language actually supports this lesser expectation – which, to me, offers a reconciliation between Indigenous and non-Indigenous interests that seeks to be fair to all. (Fairly enough, my view on this point has been challenged, given the ongoing debate on the issue of consent.)"

The author is writing that Trudeau raised the expectation among Indigenous people that the Liberal government would support the higher standard of consent.  That they are now backing down to the lesser standard of consult might result in damaged relationships with the Indigenous community.  It seems like a pretty balanced article to me.
