What this data can and can’t tell you
- A wider service area. A regional or shared police service reports one set of figures for every municipality it covers, Rosemère included.
- The index’s scale. Figures are relative to one fixed point, Canada in 2006 at 100, rather than to this year’s national number.
- What clearance means. A cleared case is one police consider solved. Whether anyone is convicted is a separate matter the rate doesn’t follow.
- An index, not a verdict. Statistics Canada builds the index from every crime police record, weighted by how seriously the courts treat it, and divides by the population. It adds a warning of its own: “The CSI is not an indicator of overall safety and should be interpreted in the broader community context.”
