I'll answer very briefly, because I already said what I had to say about this at the beginning of the meeting.
That's the normal process that's followed by committees when it comes to calling witnesses. Things are different here at the Standing Committee on Public Accounts. For a long time, the usual practice of this committee has been to invite the Auditor General as well as the deputy ministers and officials of the departments concerned in the report of the Auditor General in question.
Here we are with about a dozen meetings on ArriveCAN, which is also being studied by other committees. Witnesses are invited left and right. In this context, it's normal to have a work process that respects the will of all members of our committee. It's fine for the date to be set by the chair, but the committee members must certainly be consulted, as is the usual practice.
