What is the purpose of sentencing under section 718 of the Criminal Code of Canada?

Section 718 of the Criminal Code states that the fundamental purpose of sentencing “is to contribute…to respect for the law and the maintenance of a just, peaceful, and safe society.” This is to be achieved by imposing sentences which have, among others, the objectives of separating offenders from society, where necessary; of denouncing unlawful conduct; of general deterrence; of rehabilitation; and of promoting a “sense of responsibility in offenders, and acknowledgement of the harm done to victims and the community.” In Tapia v. United States, No. 10-5400 (U.S.S.C.), it was noted that “retribution, deterrence, incapacitation, and rehabilitation--are the four purposes of sentencing generally.”
