| British Columbia | Licensing & Consumer Services Branch, BC Housing | Homeowner Protection Act (1998-99) | Mandatory, multi-provider third-party warranty insurance |

Confidence: Verified.
Key contrasts:
- BC and Alberta require third-party home-warranty insurance with competing providers; Ontario and Quebec each use a monopoly warranty body (Tarion / GCR).
- BC has had residential-builder licensing since 1998-99 — the oldest in Canada.
- Alberta only added licensing in December 2017 — newer than Ontario's NHCLA but older than HCRA's 2021 operational launch.
- Quebec's RBQ contractor licence subclass 1.1.1/1.1.2 is broader than just new-home builders.
For Candid use: Almost all builder clients are Ontario-based, but this comparison is useful for two scenarios: (1) a builder licensed in multiple provinces who wants consistent disclosure across markets; (2) explaining to a buyer why Ontario's system works differently than what they may have experienced in BC or Alberta.
