the Chief Justice also wrote... "that trial judges are not prevented from imposing exemplary sentences that emphasize deterrence and denunciation in appropriate circumstances."
Except that is bullshit. Trial judges are bound by case law and plea bargains, they tell us that all the time in their decisions. Sentencing laws in Canada are a complete joke, they don't really exist. Whenever I hear someone spouting a maximum penalty for a crime in Canada I feel like puking. Except for first degree murder which has only one penalty, I challenge you to find a case in recent history where a Canadian judge has imposed a maximum penalty for any criminal offence regardless of how heinous an example of that crime.
This is about the legal system maintaining complete control over whether and how laws are enforced in this country.
