As you may be aware, the Government of Canada did, through the safe restart agreement, transfer additional funds to the provinces to allow them to top-up wages.
However, I would point out that, under the Constitution, with regard to property and civil rights, the regulation of this sector is the exclusive domain of provincial governments. It would be unconstitutional for the Government of Canada to impose salary levels on the provincially regulated sector. We can only do that on the federally regulated sector.
