the liberals are clearing targeting some individuals: professionals. It is obvious. 
I say it is ok to do as they plan provided they come after family trusts which really are a vehicle for the rich to avoid taxes. Trudeau has no credibility at all. He has never worked an honest days work in his life, was a part time teacher, yet lived a rich mans life. How nice. Time for folks like him and Morneau to pay their fair share. We need a tax revolution in this country to bring down the truly wealthy. The govt. has done a great job making sure the general population thinks doctors are rich. Yes, some are but the vast majority are not.
Right or wrong doctors I work with are resentful and I think changes will occur in work ethic etc. Watch.
And since these advantageous of incorporation were done in lieu of income increases 10 years ago, the provinces now have a long way to catch up as doctors have not seen increases (actually have had clawbaks and decreases) for 10 years
