The fall out from the tax revision could be a compensation issue.  A professional will state "Take away my income splitting abilities , then show me how to get to the same after tax income,and I'm good with it
If not , expect the push back to be very hard , very angry"
Doctors , are paid from the same pool of tax revenue as the well pensioned government employees, they will soon look to be compensated with a similar basket of benefits/ pensions etc. I betit nets out "more expensive" .
Mr. Morneau may have just laid waste to the best deal our  society gets.
