What area does the Longueuil crime data cover?
The Longueuil crime data cover the five cities of the Longueuil agglomeration: Longueuil, Brossard, Boucherville, Saint-Bruno-de-Montarville and Saint-Lambert, all policed by the Service de police de l’agglomération de Longueuil (SPAL). Statistics Canada’s counts imply about 458,200 residents in that area in 2025 (our calculation: incidents divided by rate).
The Crime Severity Index is a Statistics Canada measure that weights each police-reported offence by its seriousness, with Canada in 2006 set at 100. The South Shore agglomeration sits inside the Montréal census metropolitan area (CMA), so in CMA rankings it is counted together with Montréal and Laval. This guide uses the police-service figures, which describe the South Shore on its own. Our Crime Severity Index explainer covers the method.
