Trudeau welcomes the feedback, but has hinted strongly that he is unlikely to materially change the policy nor the timing.  

Whether you view the existing policy as tax incentives for risk taking, or rather as unfair loopholes, it would be reasonable to argue that trying to undo an architecture decades in the making in less than three months is irresponsible.  

And to announce this in mid-summer with a compressed consultation (so as to limit debate) makes this appear as a tax grab from a spend thrift government more than anything.

More MPs of all political stripes should denounce this.  A floor crossing is even worth considering!
