Chomedey held 94,030 people in 2021, or 21.5% of Laval: first among the six planning sectors the CISSS works with, and the only one of them made of a single neighbourhood — the other five gather between two and five. It also grew fastest between 2016 and 2021 (+6.4%, against +3.6% for the island as a whole), and it is the oldest, with a median age of 44.8. Its building stock, though, leans hard toward collective housing: 13,180 houses, detached, semi-detached or in a row, against 24,895 dwellings in apartment buildings — 34.6% houses here, where the whole island counts 56.7%. Three proportions, which we present as arithmetic of our own, sum the situation up: 22.5% of Laval households live in this sector, which holds only 13.7% of Laval's houses and one Laval apartment in three.
The number that truly decides where a dumpster goes is published one ensemble at a time — the unit the City's planning study is built on. Residential lots in Chomedey run from about 6 m wide in the Ampère area, in row houses, to about 18 m at Renaud et McNamara Estate, at Parc Saint-Martin and at the Sœurs Missionnaires Christ-Roi. In between: about 8 m in the western part of Kennedy, about 9 m in the western part of Banlieue de Chomedey, about 10 m at Val-Martin and around rues Doisy and Dale, 15 to 18 m elsewhere in that same Banlieue. Typical depths swing between 25 and 35 m. Threefold, then, from the narrowest width to the widest, inside a single sector. One caution about reading those numbers: the study measures lots, not driveways, and the house takes its share. You hold the tape measure, we hold the exact dimensions of the dumpsters — one call settles it.
The municipal framework is the same from one end of Île Jésus to the other, and it is treated in full on our regional index: dumpsters across Laval.

The 22.5% and 13.7% shares and the “one in three” are calculations made by us.
