Add about 62,300 property crimes and 22,100 other violations a year (2023–2025 average). The grid is 1,000 residents, a coloured dot for each incident a year at these rates.

What this data can and can’t tell you
- The clearance rate. Weighted like the index, so solving one assault counts for more than solving a mischief; a charge laid, recommended or otherwise resolved all count.
- Severity, weighed. The index weighs crimes rather than counting them: a serious offence moves it far more than a minor one. Statistics Canada is plain about its limits: “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.”
- One service, several municipalities. Senneville is policed by a service that covers other municipalities too, and Statistics Canada reports the service as a whole.
- What 100 means. A reading of 100 is the whole country in 2006. Half of that, 50, means half the severity per resident.
