The process has always varied in the past, depending on the circumstances. Sometimes I would reach out to the chief of staff or the senior policy adviser and say that this issue is on the radar and we should probably discuss it.
I would say that more often then not, it was reversed. I would get a call from the minister's office wanting to discuss something, and then we would have to make a decision as to whether this warranted elevating it to the minister and briefing the minister.
Typically, more formally, when ministerial briefings were arranged that I attended and briefed the minister on, that request came from the minister's office via the deputy minister's office and came over to our group. Under the act, section 102 of the Patent Act—I think Mr. Davies raised this point on Thursday—the minister has the authority to convene the chair. No corresponding authority resides in the chairperson. It has almost always come from the other direction, so I don't understand that.
