I completely agree, just as I did when Mr. Waugh put forward the motion a few months ago, at the height of the pandemic. It's still raging on, so I think we should encourage the virtual appearance of witnesses.
However, some witnesses use their appearance before a committee as an opportunity to arrange meetings on Parliament Hill, so they may wish to appear in person, and we shouldn't deny ourselves the possibility of meeting with them in person if that is their preference.
That said, I wholly agree that we should give preference to virtual participation, especially during the pandemic. Another benefit is the cost savings. I do think we should keep the door open to those who wish to appear in person, in keeping with the public health rules, of course.
