>It allows for that if the issue also is affecting non-rez lands/communities

Correct. As I said, Section 88 allows for laws "of a general nature", and specifically excludes laws pertaining to Natives.

Generally speaking, the only Canadian laws that DON'T apply on reserves are land related ones, which of course makes sense. So provincial landlord-tenant acts have no force on reserves. Everything else, from highway traffic laws to animal cruelty laws apply ... in theory. Enforcing them is another matter.
