Through you, Madam Chair, I think the issue of work and paid work and conflict of interest is one that has in fact been raised by the commissioner.
Currently the code says with regard to activities outside of Parliament that unless you're a minister or a parliamentary secretary, you can do those activities. There is the broad, general prohibition of improperly furthering another person's interests, so you'd have to capture it here, but the commissioner did raise the question of whether there is paid work that, because you're remunerated and it's inconsistent or appears inconsistent with your duties as a member, should be dealt with by the code more explicitly.
These would be the types of considerations that you might want to turn your minds to.
