“Didn’t I read about? “
Well ,indeed I did. seeing as I am an investor in 6 small enterprises here in Canada , I consider myself kind of on “ the front line”. 
( and I’m  not keen about some of the changes btw)
My partners have come from around the world, Iran, USA Lithuania, India, U.K ‘,Russia and  Winnipeg — (sense of humour guys)
I ask them frequently “ like seriously what made you pick this frozen moose pasture of a country?”
They all confirm and affirm, that Canada is where they thought they would get their shot. Their best opportunity .
Will we all cut and run?  .... we will grumble , maybe look at other tax effective structures, but right now Im not sensing a big cut and run “ in droves”. My point is that there is a lot of “stickiness” to the Canadian small medium entrepreneur.
Let’s see what the final rules are.
May common sense prevail.
