Renting in Châteauguay in 2026

Châteauguay is a South Shore city of roughly 50,800 people as of the 2021 Census, about 20 minutes from downtown Montreal via the Honoré-Mercier Bridge, which carries a reserved rush-hour lane. The city sits in the MRC de Roussillon, Quebec's most populous regional county.

The rental market is anchored by commuters using the Mercier Bridge and Route 138 corridor, along with express bus service to the Angrignon Metro terminus. Housing stock is a mix of established single-family neighbourhoods and newer apartment and townhouse developments, with Châteauguay positioning itself as one of the South Shore's larger economic hubs outside Longueuil and Brossard.

The local economy runs on the following:

• •
  The Châteauguay HVDC back-to-back converter station, the largest facility of its kind in North America
• •
  A South Shore business base the city describes as its fifth-largest economic hub, with over 1,000 businesses

• •
  Saint-Joachim-de-Châteauguay Church, a National Historic Site built between 1774 and 1797
• •
  Maison LePailleur, a museum dating to around 1792
• •
  The Châteauguay HVDC converter station, a major piece of North American electrical infrastructure

Every rental in Châteauguay is governed by the Quebec Civil Code (residential leases). Key rules that apply regardless of town size:

• •
  No fixed provincial rent-increase guideline.The TAL publishes a base percentage each year (3.1% for 2026) as one factor among several — capital expenditures and service changes can adjust it further.
• •
  Security deposits are illegal in Quebec.A landlord may only require first month's rent in advance at signing — no separate damage, key, or pet deposit of any kind.
• •
  Landlord entry requires 24 hours' written notice.For repairs, showings, or inspections.
• •
  Disputes go to the TAL.Quebec's Tribunal administratif du logement handles applications from both landlords and tenants.
• •
  No legally required move-in inspection report.A written move-in inspection is good practice but is not a Quebec Civil Code requirement.
