National Building Code of Canada
Building code recommendation
The National Building Code of Canada is the model building code of Canada. It is issued by the National Research Council of Canada. As a model code, it has no legal status until it is adopted by a jurisdiction that regulates construction.
History
The Constitution of Canada includes the regulation of building construction as a provincial responsibility. In a few cases, municipalities have been given the historic right of writing their own building code. In the early years of regulating building construction, this caused a patchwork of building codes across Canada.
In 1941, the federal government of Canada published the first National Building Code. This was adopted by the various provinces and municipalities in Canada during the next 20 years.
On 1 August 1947, the Division of Building Research, later named the Institute for Research in Construction (NRC-IRC) and today known as NRC Construction Research Centre, was established to provide a research service to the construction industry and to help ensure affordable and safe housing for a growing population of Canadians. Its founding head was Robert Legget.

Why this record matters
“National Building Code of Canada” is worth following because a concise public description often conceals a longer documentary argument. Here, National, Building and Code provides the most credible route into that argument.
Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 12, 2026. The linked authority identifier is Q6971140. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1941 and 1947.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
