Repeated security audits at major airports such as YYZ show repeated and regular occurrences of airside staff not getting screened for weeks at a time.
Essentially, many airside staff don’t get screened much, but passengers get the Theatre. Recommendations from repeated audits to change this did nothing.
CBC has a whole piece on it. Once post 911, and again years later (nothing changed).
So many holes in airport security, it’s ridiculous when compared to the passengers’ routine denigrations.
