What's Changing in the Town of Mount Royal: Zoning, the Beaumont PPU, Construction and Free Water-Damage Inspections
New acquired-rights rules, parking for multi-unit buildings, the postponed Beaumont PPU, Hydro-Québec and Côte-de-Liesse work, free water-damage inspections: what is changing in the Town of Mount Royal for owners and buyers.
Every quarter, our team reviews the decisions and projects that change daily life in our areas, and what they mean for owners and buyers. Here is what to know about the Town of Mount Royal this fall 2026. Facts checked on November 5, 2026.
At a glance
- Zoning: on September 22, council adopted new rules on buildings protected by acquired rights, and three other amendments were on the October 20 agenda (parking for multi-unit buildings, Rue Melbourne, Avenue Brookfield).
- Beaumont PPU: the program that will guide the redevelopment of the south-east sector, near Acadie station, was to be adopted in May 2026; its adoption has been postponed, with no new date.
- Construction: Hydro-Québec will replace about 300 poles in the east sector until fall 2027, the Côte-de-Liesse and Rockland roadways are being rebuilt, and the sports and community centre was 52% complete on October 20.
- Water damage: since September 4, all owners of an eligible building can request a free inspection against sewer backups and water damage.
Zoning: rules that change before you renovate, extend or buy
On September 22, 2026, council adopted By-law 1441-25, which replaces zoning provisions on non-conforming buildings and uses protected by acquired rights, meaning buildings or uses that no longer meet current standards. Three other amendments followed: for H-3 multi-unit buildings, required parking would drop from 1.25 to 1 space per unit at minimum, and from 1.5 to 1.25 at maximum, with all spaces indoors; on Rue Melbourne, between Canora and Fleming, two semi-detached houses could be joined into a single home without merging the lots; near Avenue Brookfield, a porch or terrace could extend up to 3 metres into the rear setback. These three amendments were on the agenda of the October 20 meeting; the minutes, which will confirm their outcome, had not been published as of November 5.
What it means: if your house no longer meets current zoning, for example a setback that is too narrow or an older garage, its potential for an extension or for rebuilding after damage depends on these rules. Before buying to extend or starting work, check with the Town which text is in force and what it allows for your property.
Beaumont PPU: an area whose rules are not set yet
The Beaumont specific planning program (PPU) covers 16.7 hectares in the south-east part of the Town of Mount Royal, near Acadie station. The first draft, adopted on February 17, 2026 and presented at a public consultation on March 25, targets heights of 4 to 8 storeys for commercial and institutional uses, and 6 to 8 storeys near the MIL campus footbridge. Adoption, planned for May 2026, has been postponed; no new date has been published.
What it means: the targeted heights and density have not been adopted. For owners or buyers in the Beaumont sector, the future rules remain open: follow the next steps before basing a decision on what could be built there.
2026-2027 construction: what is happening near you
In the east sector, between Jean-Talon, de l'Acadie, Côte-de-Liesse and Canora, Hydro-Québec will replace conductors, transformers and about 300 poles, with tree pruning and, where needed, tree removal: preliminary work from fall 2026 to spring 2027, then the main work from spring to fall 2027. Hydro-Québec says line capacity will be doubled. On September 16, council authorized spending of $6,189,048.14 to rebuild the roadway on Chemin Côte-de-Liesse and Chemin Rockland; according to the Town, whatever is not finished this fall will resume in spring 2027. Finally, the new sports and community centre was 52% complete as of October 20, with a preliminary opening in spring 2028, subject to change.
What it means: in the east sector, expect about a year of work on the power grid, with noise, tree pruning and possibly planned outages. If you sell during this period, tell buyers about the schedule; if you buy, ask about it. In the end: a sturdier grid and a new neighbourhood facility downtown.
Resilient Properties: a free inspection against water damage
Launched in January 2026, the Resilient Properties program has been open since September 4 to all owners of an eligible building, whether or not they have reported damage since June 15, 2022. A firm hired by the Town inspects the plumbing and exterior elements free of charge, then provides a report with recommendations. Corrective work remains the owner's responsibility. Inspections take place until the end of fall 2026 or from spring 2027, and the program is planned to run until 2028.
What it means: a free inspection report helps identify a water-damage risk and fix it before selling, or better understand a property you have just bought. A seller who has done the recommended work can document it for buyers.
What to watch in the coming months
- The minutes of the October 20 meeting, which will confirm the adoption of the rules on parking for multi-unit buildings, Rue Melbourne and Avenue Brookfield.
- The new schedule for the Beaumont PPU.
- The Town of Mount Royal's 2027 budget: for reference, the 2026 budget was adopted on January 23, 2026.
- The start of Hydro-Québec's preliminary work in the east sector, by spring 2027.
