It has happened a couple of times. I fully agree with Mr. Green's intervention. Obviously, the witness is required to provide a fulsome answer, to the best of their ability, to any of the questions that are put forward by members of the committee.
As you said, Chair, it's up to the committee if we're willing to accept an answer in writing. That's the proposal from Mr. Green. I don't have any objection to that. It should be noted, though, that it remains the committee's prerogative whether that information is held in confidence, or whether we publish that information—if it's perhaps, simply put, in the public interest—but certainly there is no discretion on the part of the witness to answer or not to answer the question.
While we don't have an objection to the response to this question from Mr. Villemure being provided in writing, an answer must be provided.
