I don't believe there's an issue.
Town cheques bear two signatures; the Mayor's and Treasurer's. Security is the objective.
Theoretically, both signatures guarantee propriety.
I'm not sure how effective the security if the parties are aligned on the same side of the operation.
For example if both believe it appropriate for a Mayor to personally retain legal counsel for a purpose having nothing to do with town function and more to do with obsessive compulsion.
A Treasurer is a Statutary Officer. I have always understood that to mean legal authority and responsibility to ensure adherence to Provincial Statutes
Bylaws and Contracts also require signatures of Mayor and Municipal Clerk.
The Municipal Clerk and Deputy Clerk are also Statutory Officers with a wider role and many separate responsibilities including Commissioner of Oaths.
Unlike Clerk and Treasurer, no Statutary authority attaches to a Chief Administrative Officer .
I believe I have only seen CAO signature on Reports to Council.
Reports of Directors bear signatures of the Director and CAO. Reports form a record. The record is confirmed by By-law at the end of every Council Meeting.
CAO is not a statutory officer.
You know, I do not claim professional status. My understanding of process comes from
engagement in town affairs over a lengthy period . Laws change and sometimes lapse.
The less collective experience or common sense exists on a Council, the easier to mislead.
That they might be misled by StatutRy Officers is unthinkable but it happens.
When it happens, it is inexcusable.
Public servants are not immune to bad judgement.
