Safety Bulletin 0000021 'Adoption of Updated Fuel Safety Codes' (Feb 28, 2023) moved the province to the 2020 (B149.1:20) edition with a transition grace period.

What does "edition in force" mean?+

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.

Does the whole province use the same code?+

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.

Which model codes does this directory track?+

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.

How do I read the official code for free?+

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. Each result links to the official source.

Why does this directory not show the actual code text?+

Trade codes are copyrighted by their standards bodies (CSA Group and the National Research Council of Canada). This directory publishes only factual adoption data — which edition is in force, when it took effect, who the authority is, whether it is amended, and where to read it officially — and links you to the official source for the code text itself.
