I have not been talking about accused individuals. Every Canadian has rights guaranteed by the Charter of Rights that says no one has to provide evidence against himself or herself.
What I'm looking for is the authority and power, which exists for the vast majority of provincial electoral bodies, as well as for the Competition Bureau and many other regulatory agencies, to require a person to attend an interview if that person, in the view of the investigator, may have in his or her possession information that is relevant to an investigation. That power would be exercised only with the authorization of the courts. It's not a free ride for investigators—quite the opposite.
Again, if in the course of an interview an individual provides evidence that may be against their interests, the interview has to stop. They have to be told right away. In any case, the information cannot be used against them.
