In Canada, the courts always have the final say with regard to sentencing. Nevertheless, plea bargaining has become an accepted part of the criminal justice system although judges and Crown attorneys are often reluctant to refer to it as such. In most Canadian criminal proceedings, the Crown has the ability to recommend a lighter sentence than it would seek following a guilty verdict in exchange for a guilty plea.
Like other common law jurisdictions, the Crown can also agree to withdraw some charges against the defendant in exchange for a guilty plea. This has become standard procedure for certain offences such as impaired driving. Note that in the case of hybrid offences, the Crown must make a binding decision as to whether to proceed summarily or by indictment prior to the defendant making his or her plea. If the Crown elects to proceed summarily and the defendant then pleads not guilty, the Crown cannot change its election. Therefore, the Crown is not in a position to offer to proceed summarily in exchange for a guilty plea.
Canadian judges are not bound by the Crown's sentencing recommendations and could impose harsher penalties. Therefore, the Crown and the defence will often make a joint submission where they will both recommend the same sentence, or (much more commonly) a relatively narrow range (with the Crown arguing for a sentence at the upper end of the range and the defence arguing for a sentence at the lower end) so as to maintain the visibility of the judge's ability to exercise discretion.
Judges are not bound to impose a sentence within the range of a joint submission, and a judge's disregard for a joint submission is not in itself grounds for the sentence to be altered on appeal. However, if a judge routinely disregards joint submissions, that judge would compromise the ability of the Crown to offer meaningful incentives for defendants to plead guilty. Defence lawyers would become reluctant to enter into joint submissions if they were thought to be of little value with a particular judge, which would thus result in otherwise avoidable trials.
For these reasons, Canadian judges will normally impose a sentence within the range of any joint submission
