Feds Allowed to Step Into Provincial Boundaries For Tax Purposes - What Next, a FEDERAL Land Transfter Tax on Top of Municipal and Provincial Land Transfer Tax? Housing is Also a "Concern"

Great, Feds allowed to step into provincial boundaries for tax purposes.  What next, a FEDERAL land transfter tax on top of municipal and provincial land transfer tax? 

Insert "land transfer taxes" in place of "carbon pricing".

"...The court thus accepts that Parliament can constitutionally establish a “floor” of carbon pricing across Canada because of the national concern doctrine, under which the federal government can exercise jurisdictional power not explicitly granted to it in the Constitution Act of 1867..."
