Where AvRegs gets its information
AvRegs copies Canada’s aviation rules and guidance from the official sources below. We check them for changes, most of them every day. Every change we find shows on What’s Changed.
For each source: what we keep, how often we check, how much of it is in AvRegs now, and the last day we found a change and stored a new copy. Our last full check finished 2026-10-30 11:20 UTC. AvRegs is not an official version, so each source links to its official page.

Not covered (yet)
AvRegs does not hold these. Check them with the publisher.
Service difficulty reports Not yet
Transport Canada's service difficulty reports are not in AvRegs. Its public search needs a manufacturer, has no link to each report, and the reports are operators' own write-ups, so AvRegs cannot list them the way it lists ADs.
Commercial and Business Aviation Advisory Circulars Not yet
These circulars are not in AvRegs. Transport Canada's Advisory Circulars (AC series) are.
NOTAMs Not yet
AvRegs does not hold NOTAMs. Get them from NAV CANADA, then paste them into the AvRegs NOTAM timeline to see when each one applies, in UTC. They stay in your browser.
Protected air carrier security measures Not public
These are not published. Transport Canada gives them only to the people who must follow them.
