As far as I can see, some of them do still exist, but they're hard to find.
They are being phased out, into DAODs, like CFAOs
For example - CPAO 9.01 Employee Training has been superceeded by DAOD 5031-50 Civilian Learning and Professional Development.
Where possible, they're amalgamating the CPAOs and CFAOs. Before, even if the policy was the same for both groups, there was a separate CFAO and a CPAO. Now, some DAODs apply to CAF members only, some to DND employees only, and some to CAF members and DND employees.
