Effectiveness Of Mitigating And Aggravating Factor Guidelines
1. Overview: Mitigating and Aggravating Factors
In criminal sentencing, mitigating and aggravating factors help judges determine an appropriate sentence by considering both the circumstances of the offender and the nature of the offence.
Mitigating factors reduce the severity of the sentence:
First-time offender status
Remorse or apology
Cooperation with authorities
Age, mental health, or addiction issues
Lack of prior criminal record
Aggravating factors increase the severity:
Use of violence or weapons
Vulnerability of the victim
Breach of trust
Prior criminal record
Hate-motivated offences
Legal Framework:
Criminal Code s. 718.2(a–b): Considers aggravating and mitigating circumstances.
s. 718.1: Sentences must be proportionate, just, and reflect denunciation and deterrence.
2. Purpose of Guidelines
Promote consistency in sentencing.
Ensure proportionality between offence gravity and sentence.
Encourage judicial discretion while providing structure.
Protect public interest and offender rehabilitation opportunities.
