Statement from MPP Jack MacLaren


The following is a statement issued by Carleton-Mississippi Mills MPP Jack MacLaren on his support for a zero tolerance policy for sexual assault:

March 28th, 2017 – For Immediate Release


“Yesterday, in the House while discussing due process in our justice system with respect to Bill 87, I made comments which could be misconstrued.  I want to take a moment to clarify my position.  While I believe strongly in due process for anyone accused of a crime, I unequivocally support a zero tolerance policy for sexual assaults and abuse. Too many criminals are released with light punishments and that needs to stop.”
