Pesticide qualification is separate from responsibility for treatment
Québec’s bed-bug guide recommends checking that the extermination company and technicians hold appropriate pesticide licences/certificates. Owner-versus-tenant costs in a dispute depend on the facts and applicable tenancy law; municipal pesticide permissions alone do not decide payment. Québec official extermination guidance
Montréal apartment infestations: owner first, borough 311 next
If you rent and find bed bugs, Québec instructs tenants to inform the building owner immediately so that an appropriately certified exterminator can be contacted. Keep written notice, dated photos and treatment instructions. For ongoing unsanitary conditions involving bed bugs, vermin or water damage, the Montréal Fire Safety Department directs residents to the borough’s urban planning and business services division via 311 or 514-872-0311, not to fire-prevention staff.

What changes in Montréal
Four property checks for Montréal
Inspect where utilities and additions meet the building; those transitions often deserve attention before more trapping.
Treat the trail as evidence: look for the crack, food source or damp area that keeps drawing activity.
A concealed or high nest near regular foot traffic is a different risk from distant outdoor foraging.
For bed bugs or cockroaches, notify the responsible property manager early because adjoining units may need coordinated inspection.
In Montréal, check the treatment site and the borough
Montréal’s pesticide rules concern the sale and use of specified products. A homeowner considering an outdoor lawn or garden application should first identify the product and active ingredient, then check the City’s permitted-product route. A contractor’s general statement that a product is federally registered does not settle the City rule. The municipality also tells residents to confirm that a professional applicator has the required permit.
An indoor rodent response follows a different path: the City says a municipal permit is not required for the relevant pesticide use inside a building or sewer. That does not waive the Canadian label or Québec requirements. For an apartment, report activity near shared waste storage, risers or adjoining units to the landlord or manager and ask how entry, sanitation and follow-up across units will be handled.
Montréal is organized by borough, and property-maintenance enforcement or local service routes can depend on the address. Search the City’s page with the correct borough selected rather than importing a neighbour borough’s fine or procedure. This guide intentionally does not describe a single borough’s extermination rule as if it applied everywhere on the island.
Quebec and Montréal: rule check
Canada controls pesticide registration and the product label, while Quebec can add its own use and applicator rules. Health Canada also advises checking municipal restrictions for lawn and garden pesticide use.
