As we wrote in our Security Team Update last November [1], Joanna
continues to sign Qubes Canaries:

"However, due to the nature of PGP keys, there is no way to guarantee
that Joanna will not retain a copy of the QMSK after transferring
ownership to Marek. Since anyone in possession of the QMSK is a
potential attack vector against the project, Joanna will continue to
sign Qubes Canaries in perpetuity."

Therefore, a trusted signing key belonging to Joanna must remain in the
Qubes Security Pack (secpack) [2] for this purpose.

We do these things in a secure, transparent manner when necessary and
appropriate. For example, the Security Team Update [1] added Simon to
the Qubes Security Team, and you can see that his Security Team signing
key was added to the secpack shortly thereafter. [3] You can also see
that he has signed all Canaries and QSBs since then. [4]
