Concurrent And Consecutive Sentences
1. Overview: Concurrent vs Consecutive Sentences
In Canada, when an offender is convicted of multiple offences, the sentencing court must decide whether sentences should run:
Concurrently – All sentences are served at the same time, with the longest term governing the total time in custody.
Consecutively – Sentences are served back-to-back, summing the durations for total time in custody.
Statutory Provisions:
Criminal Code s. 718.3: Sets factors for consecutive sentences.
s. 719(3): Courts may order sentences to be concurrent or consecutive.
2. Principles Guiding Concurrent vs Consecutive Sentences
Totality Principle:
Sentences must be proportionate to the overall criminality and avoid being unduly harsh.
Aggravating and Mitigating Factors:
Courts weigh gravity of offences, harm to victims, and offender’s role.
Overlap of Offences:
If offences arise from same incident, courts prefer concurrent sentences.
Distinct acts may justify consecutive sentences.
Judicial Discretion:
Courts have discretion; appellate courts intervene if sentences are unreasonable or disproportionate.

4. Key Principles Derived from Case Law
| Principle | Explanation | Case Reference |
|---|---|---|
| Totality Principle | Overall sentence must be proportionate | R v. M. (C.A.), R v. Latimer |
| Distinct vs Overlapping Acts | Consecutive for distinct acts, concurrent for related acts | R v. M. (C.A.), R v. C.A.M. |
| Public Safety & Deterrence | Serious offences may justify consecutive sentences | R v. Nur, R v. Nasogaluak |
| Appellate Review | Courts can vary sentences if unreasonable | R v. Arcand |
| Judicial Discretion | Courts weigh circumstances, harm, and offender role | R v. Proulx, R v. Latimer |
5. Analysis of Effectiveness
Strengths:
Provides flexibility to reflect gravity and distinctness of offences.
Totality principle prevents excessive or crushing sentences.
Appellate courts ensure consistency and fairness across cases.
Limitations:
Discretion may lead to variation across jurisdictions.
Complexity may make sentences less predictable.
