Part of our Explainer series: plain-language guides to the bylaws and regulations that shape life in Ormstown.

PIIA 101: the bylaw that judges how your project looks — and where it applies in Ormstown

In three sectors of Ormstown, a building project isn't approved by meeting measurements alone. It must also pass a qualitative review of its appearance and fit — the PIIA — before a permit is issued (Règl. 152-2023, art. 1.2, 1.7).

Two kinds of rules

Ormstown's building rules come in two layers. The first is quantitative: the zoning bylaw (148-2023) and its companions set numbers — permitted uses, setbacks, heights, sign dimensions. Either you meet them or you don't.

The second layer is qualitative, and that's the PIIA. Règlement 152-2023 states its objective at article 1.2: to frame the siting and architecture of buildings and the layout of lots by setting objectives and planning criteria allowing « un contrôle qualitatif de l'aménagement » inside the designated zones. In plain terms: in certain parts of Ormstown, the Municipality doesn't just ask whether you can build — it asks whether what you build will fit.

This is a standard tool under Québec's Loi sur l'aménagement et l'urbanisme, used across the province to protect village cores and heritage streetscapes. Ormstown's current version, Règlement 152-2023, replaced the previous PIIA bylaw, number 65-2011 (art. 1.3).

Two structural rules connect the layers:

• Zoning comes first. A PIIA application isn't sent for review until it conforms to the zoning, subdivision, and construction bylaws (art. 3.6) — and the permit only issues if that conformity holds (art. 3.9). PIIA approval never overrides zoning.
• When rules conflict, the stricter one wins. Article 1.6 provides that where the PIIA is incompatible with another municipal bylaw, « la disposition la plus restrictive ou prohibitive doit s'appliquer ».

Does the PIIA apply to your property?

Article 1.7 designates three sectors:

1. The architectural core — the historic village centre: zones C-5, MXT-1 to MXT-3, P-5 to P-9, P-11, R-13, R-15 to R-17, and R-29 to R-32 (art. 1.7 a)). This sector carries the most extensive requirements, from new construction down to repainting a building a different colour (art. 4.2 — detailed in Parts 2 and 3 of this series).
2. Route 201 South and zone C-7 — the commercial and industrial corridor: zones C-7, C-8 to C-10, and I-1 (art. 1.7 b)). Covered in Part 4.
3. Zone R-37 (rue Isabelle) (art. 1.7 c)) — where the PIIA applies to construction and expansion of a main building (art. 4.14).

A fourth application is territory-wide: any detached accessory dwelling unit (UHAD) anywhere in Ormstown requires PIIA approval (art. 1.7, second paragraph). That's Part 5.

Zone boundaries are those drawn on the zoning plan of Règlement 148-2023 (art. 1.7, closing paragraph). Unsure which zone your property falls in? The zoning maps are linked below, or call the Service de l'urbanisme at 450 829-2625.

What triggers a review differs by sector — article 1.8 states the covered interventions are set out sector by sector in Chapter 4 of the bylaw. The rest of this series walks through each one.

Who's involved

• The designated officer (fonctionnaire désigné) administers and applies the bylaw (art. 2.1–2.2). Your first point of contact, and the person who verifies your file.
• The Urban Planning Advisory Committee (CCU) — a council-appointed committee that analyzes each project against the bylaw's objectives and recommends approval, conditional approval, or rejection (art. 3.7).
• Council — which alone makes the final decision, by resolution, taking the CCU's recommendation into account. Council may also hear comments from the public (art. 3.8).

The process, start to finish

1. File a complete application with the Service de l'urbanisme (art. 3.2). Documents depend on the project: article 3.4 lists what's needed for a construction permit (site plans, materials and colours, façade drawings, roof pitch, and more); article 3.5 covers certificates — renovations, signs, and front-yard parking each have their own list. Everything required for the underlying permit must also be available for the PIIA analysis (art. 3.3).
2. Conformity check. The designated officer verifies the file against the zoning, subdivision, and construction bylaws and confirms it's complete. Non-conforming, incomplete, or imprecise files are held until fixed (art. 3.6) — the clock effectively doesn't start until your file is in order.
3. CCU analysis and recommendation (art. 3.7).
4. Council decision by resolution (art. 3.8). A refusal must state its reasons, and council may suggest modifications for a revised submission. A copy of the resolution goes to the applicant.
5. Permit issued once fees are paid, provided the application remains conforming (art. 3.9).

Study fees are set in the Municipality's tariff bylaw (art. 2.4) — confirm the current amount with the urbanisme department before filing.

The rule most people learn the hard way: any modification to plans or documents after council approval requires presenting a brand-new application (art. 3.10). Finalize every design choice before the file goes in.

What happens if you don't comply

Article 2.5 makes it an offence to fail to comply with the bylaw, to make false declarations or file erroneous documents to obtain a permit, to obstruct the bylaw's application, or to falsify a permit. Under article 2.7, fines run $500 to $1,000 for individuals and $600 to $2,000 for legal persons on a first offence, rising to $800–$2,000 and $800–$4,000 on recidivism — and a continuing infraction « constitue, jour par jour, une offense séparée ». The Municipality may also pursue any other civil or penal recourse, including the remedies at articles 227 to 233 of the Loi sur l'aménagement et l'urbanisme (art. 2.7).

What this means for residents

• Check your zone before you plan. If you're in a PIIA sector, the qualitative review shapes what designs are realistic — better to know before you fall in love with a colour or order materials.
• A complete file is a faster file. Incomplete applications are simply held (art. 3.6); gathering photos, sketches, samples, and colour information up front keeps your project moving.
• Decisions are made in public. CCU recommendations land at council, which decides by resolution at a public meeting — and refusals must be motivated (art. 3.8). Residents can follow these decisions in the council minutes.
• The system is criteria-based, not taste-based — in principle. The bylaw's objectives and criteria (Chapter 4) are the yardstick. The rest of this series looks at exactly what those criteria say.
