I would add, to complete your answer, that there was a case in Quebec some years ago involving the government's decision to amalgamate municipalities. There was a challenge based on section 16 of the Canadian Charter of Rights and Freedoms. This is often the section of the charter that is raised in matters involving provincial or municipal jurisdictions.
At the time, commissioner Dyane Adam intervened in that case because the case raised issues related to the interpretation of section 16 of the charter. That's an example of where, sometimes, even provincial jurisdiction issues can be brought forward and receive funding, because they're basing their request on section 16 of the charter.
