Given that you were a member of the Standing Committee on Public Accounts, I could give you an example related to that committee. It asks each department to come up with an action plan and to report back to the committee regarding that plan.
I would strongly encourage this committee to use the same approach. You could ask each department to develop an action plan every year and to submit an annual report to you, as is done at the Standing Committee on Public Accounts.
That would be one way to ensure that the departments are accountable to parliamentarians.
You are truly the watchdogs, not me.
