Patefacta, the Canadian Drug Explorer

Why it surfaced

Patefacta makes provenance part of the interface: results link back to official records, releases carry checksums and manifests, and the site says its active snapshot matched 20 official records exactly. It also draws unusually clear boundaries around what the data does not provide—no dosing advice, availability information, interchangeability guidance, or clinical recommendations.

A public search interface for Health Canada Drug Product Database records, with filters for drug names, DINs, ingredients, companies, and market status.
