A277.ca is an independent registry of factory-built housing plants certified to CSA A277 — in Canada and internationally.
One place to check whether a plant is certified, by whom, for what, and when that was last confirmed.
CSA A277 is the certification that lets a factory build housing modules under a certifier's ongoing quality program. Until now there was no single, public list of which plants hold it. A277.ca aggregates them into one searchable registry and keeps it current.
Every certified listing is drawn from the public records of accredited certification bodies — QAI Laboratories, Intertek, CSA Group, LabTest Certification, and International Testing Laboratory. Each listing links back to the certifier's own record so you can confirm it at the source, and carries a Last verified date. The registry is re-checked against those records every month.
A plant can claim its listing to add a logo, description, photos, products, and contact details. That profile content is owned by the manufacturer; the certification record stays locked to the certifier's data. Claiming and being listed are free. Claim your listing →
A277.ca is not a certification body and is not affiliated with any. We don't issue or influence certifications, and we don't sell or broker buildings. A plant appears here because a certifier's public record shows it certified — not because it paid to be listed.
