I would support putting a section about apparent conflict of interest in the act.
If it's of interest, you might look at B.C.'s statute, the Members' Conflict of Interest Act, section 2, because it has an explicit rule about apparent conflict of interest. It's one of the few statutes across the country that does, and it's had commissioners' reports on it and how it works, particularly reports by former commissioner Oliver and former commissioner Fraser in B.C.
I would suggest making use of that knowledge.
