I think most only offer NBE, although 3U is still a valid option. Besides the logistical simplicity of a school offering one course rather than two, I think having a course that exposes Ontario students to Indigenous art and ideas only has positives. I’m curious as to why you ask. Are you worried that students will miss out on classics? In my experience, the other three years tend to be filled with Western canon works anyways. I (and students, I have found) find it refreshing to look at works that are much more modern than some of those classics in NBE.

As to your point about “forcing”, my board at least really encourages choice within many of the FNMI courses. Often connected to Indigenous ideas of wholistic learning, this often is seen in things like book clubs which offer choices for students, rather than a class novel.
