The catalogue starts with official Canadian licence records. Other checks need their own research. Here is what is connected, what has been retrieved, and what remains unverified.

This public edition uses checked-in source records. Updates appear after editorial source changes are published; this site does not run a live refresh job.
“Last retrieved” records when this app successfully fetched data. It does not mean the upstream authority updated the record on that day. The initial catalogue is a dated snapshot; scheduled refreshes require an operator to configure the provided refresh job.
Where data could not be matched or verified, the interface preserves the unknown state. It never fills missing testing or recall results with a passing mark.
