Electrical code in Quebec

Quebec has adopted CSA C22.10:26 (Construction Code, Chapter V — Electricity; Canadian Electrical Code Part I, 25th ed. / CSA C22.1:21, with Québec amendments), effective March 26, 2026. The adopting authority is Régie du bâtiment du Québec (RBQ). Verified June 28, 2026.

Chapter V — Electricity of the Quebec Construction Code adopts the Canadian Electrical Code Part I (CSA C22.1) with Québec-specific amendments, published as CSA C22.10. The 2026 edition (CSA C22.10:26, based on the 25th-edition CEC / CSA C22.1:21) came into force on 2026-03-26, replacing the 2018 edition (CSA C22.10-18, in force since 2018-10-01). A transition period applies during which work begun under the earlier edition may continue under the 2018 provisions.

It is the specific edition of a model code (for example CSA C22.1:24 or the 2020 National Building Code) that a province has legally adopted and currently enforces. Codes are republished on roughly three-year cycles, and each jurisdiction adopts a new edition on its own schedule — often with amendments — so the edition in force varies by place and by discipline.

Not always. Many jurisdictions set a baseline edition for the whole province, but local building departments (the authority having jurisdiction, or AHJ) can amend it or enforce a different edition. Some places leave most adoption to local jurisdictions, and a few large cities run their own codes. Always confirm with your AHJ.

The Canadian Electrical Code (CSA C22.1) for electrical, the National Building, Plumbing and Fire Codes of Canada and their provincial editions for building, plumbing and fire, and CSA B149.1 for gas.

The National Research Council publishes the national model codes — building, plumbing, fire and energy — as free downloads. CSA standards such as the Canadian Electrical Code and CSA B149.1 usually have to be bought, though some provinces give free read-only access through their own portals.
