Montreal, QC · Commercial Cleaning & Janitorial
The 25 Best-Rated Commercial Cleaning & Janitorial in Montreal
Ranked from 109 operating commercial cleaning & janitorial businesses in Montreal, QC that carry at least 20 Google reviews. Updated 2026-08-19.
How this is ranked
By Google rating, weighted by how many reviews it rests on. A rating is pulled toward the local average (4.83 across the 109 businesses considered) in proportion to how thin its review count is, so a lone 5.0 from 20 reviews cannot outrank a 4.8 from 900. No payment, placement or editorial judgement affects the order (a paid placement, where one appears, is labelled and sits outside the list), and businesses that have claimed their listing get no lift — the mark below only says the listing has an owner behind it.
