I agree with an increase in RRSP limits.  It should be a % of income and not capped.  Then I would feel more comfortable that I can save for a reasonable retirement (without using a Prof Corp).  Take away other tax breaks / deductions, and focus on encouraging savings for retirement.  Otherwise we will be forced to support the elderly with public money anyway or have people work much longer than they should or can.  That can be dangerous for patients when docs get too old.
