Source files
Official classification files plus local Canada country-pack datasets used to assemble the site.
Official hierarchy and definition source: Statistics Canada.
Official tax and business authority reference: Canada Revenue Agency (CRA).
Local datasets now include country-profile.json, tax-regimes-ca-2026.json, and compliance-rules.json under src/data.
The local country pack supplies reusable labels, authorities, filing names, and methodology rules without rewriting official code titles.
