the tory media is agitating for a scrap.
but, the reality is that quebeckers made an informed choice in electing this government, which is now carrying out a democratic mandate to reduce migration; this is the popular will. for trudeau to come out swinging would be horribly tone deaf, and no doubt just be shooting himself in the foot.
there are legal questions of jurisdiction under the constitution, as well as rights to be upheld. these arguments are best had in a court of law - and let us all agree, at least, that the rule of law should be upheld.
but, immigration is a public policy question and subject to the sovereign will, and that must be respected.
we might be better off trying to understand the root causes - policy failures- that produced the backlash in order to adjust, rather than aimlessly flail against a clear mandate.
