No, they do not fall under my jurisdiction.
Basically, my jurisdiction is to deal with issues of conflict of interest by elected officials like yourself or by people who are what the act calls reporting public office holders, who are basically people appointed by Governor in Council and have senior positions.
In this case, none of the people you mentioned fall under either category.
There are obviously other institutions that deal with this, primarily the Commissioner of Public Sector Integrity, and there are provisions under the Public Service Employment Act, etc.
These activities, like double dipping, etc., are clearly not ethical and should be pursued, but they're not part of my mandate.
