Practical planning information for modular developments in Canada. It is general guidance, not legal advice, engineering advice, or a promise that a project will be approved.
Important: Building permits, certifications and regulatory approvals are project- and jurisdiction-specific. This information is general guidance only and does not guarantee approval, replace professional advice, or confirm compliance for any project. Always consult the applicable authority and qualified Canadian professionals.

What this page gives you
We do not publish client permits, engineering reports, inspection records, or other project-specific documents here.
What we do provide is a clear starting point. It covers the main questions that should be answered before a modular building is ordered, shipped, or placed on a Canadian site.
The final decision always belongs to the applicable authority and the qualified professionals working on your project.
The big three
The National Building Code of Canada 2020 is a model code. Provinces and territories adopt it, change it, and set their own effective dates. Local zoning bylaws can also control use, setbacks, height, parking, servicing, and fire access. The first question is which code edition and local rules apply at your project address.
CSA A277 covers the certification procedure for prefabricated buildings, modules, and panels made in a factory. It does not automatically cover foundations, anchoring, site connections, installation, or work completed outside the certified factory program. Electrical work must also follow the applicable edition of CSA C22.1, Canadian Electrical Code, Part I. Ask for the factory certificate, certification body, standard edition, building type, and written scope.
Large modules may need over-dimensional or overweight permits. The carrier may also need a checked route, bridge and overhead-clearance reviews, escort vehicles, or municipal road permissions. Seasonal road restrictions, turning space, crane access, and weak ground can change the delivery plan. Confirm these points before final dimensions are locked.
Provincial variations
Each province has its own amendments, effective dates, and approval process. Municipalities and other authorities may also control zoning, permits, plan review, inspections, and occupancy. We do not guarantee provincial compliance. We help clients identify the right authority and the documents that authority is likely to request.
Alberta uses the National Building Code - 2023 Alberta Edition, based on NBC 2020. It came into force on May 1, 2024. Energy Performance Tier 1 is the minimum level for the applicable housing and small-building provisions. Confirm the permit authority, current STANDATA, energy pathway, and local land-use requirements.

Most provisions came into effect on March 8, 2024, while some requirements had later transition dates. The City of Vancouver has its own building bylaw, and some other jurisdictions may follow different arrangements. Confirm the project location before choosing the code and approval path.
Official source: British Columbia codesThe 2024 Ontario Building Code adopts NBC 2020 with Ontario amendments. It came into effect on January 1, 2025, with transition provisions for certain work already underway. Factory certification can address work completed under a certified program, but foundations, services, anchoring, installation, and other site work still need project-specific review.
Official source: Ontario Building CodeChapter I, Building, of the Quebec Construction Code incorporates an amended version of NBC 2020. The updated chapter came into force on April 17, 2025. Quebec changes affect accessibility, structural design, fire protection, building-envelope requirements, and other technical areas.
