Clearance Rate
Understanding Police Clearance Rates in Canada
What is the Clearance Rate?
The clearance rate measures the percentage of reported crimes that police have resolved. A crime is considered "cleared" when police have identified at least one suspect and either laid a charge or resolved the incident through other means.
Canada's national clearance rate is approximately 35-40%, meaning roughly one-third of all reported crimes result in a suspect being identified.
Cleared by Charge vs Otherwise
Cleared by Charge: The suspect has been formally charged with the offence. This is the traditional measure of "solving" a crime.
Cleared Otherwise: The police have identified the suspect but cannot lay a charge. Reasons include: the suspect has died, the victim refuses to proceed, diplomatic immunity, the suspect is already serving a sentence for another offence, or diversion programs.
Both types count toward the total clearance rate.
Clearance Rates by Crime Type
Clearance rates vary dramatically by crime type:
- Homicide: ~75% (highest priority, most resources allocated)
- Assault: ~55% (victim usually knows the offender)
- Sexual Assault: ~45% (lower due to evidence challenges)
- Robbery: ~30% (strangers often involved)
- Break and Enter: ~15% (very difficult to solve)
- Theft Under $5,000: ~10% (low priority, few leads)
- Motor Vehicle Theft: ~12% (often organized crime)
Violent crimes generally have higher clearance rates because victims can often identify the offender.
Frequently Asked Questions
What is a good clearance rate?
It depends on the crime type. For violent crimes, above 50% is considered good. For property crimes, even 20% can be considered above average due to the difficulty of solving these cases.
Why are property crime clearance rates so low?
Property crimes often leave little physical evidence, rarely have witnesses, and involve unknown offenders. Police resources are also prioritized toward violent crimes.
Does a low clearance rate mean police are ineffective?
Not necessarily. Clearance rates are affected by many factors including crime type, available evidence, community cooperation, and resource allocation. Some crimes are inherently harder to solve.
How does Canada's clearance rate compare internationally?
Canada's overall clearance rate of ~35% is comparable to the UK and Australia. The US has a similar rate for violent crimes but lower for property crimes.
What happens when a crime is not cleared?
Unsolved cases remain open and can be revisited if new evidence emerges. Cold case units in major police services regularly review unsolved crimes, particularly homicides.
