Certainly.
According to the plan distributed on November 7, witnesses were supposed to be invited to today's meeting. They were indeed invited. The Citizen Lab representative is in Taiwan and the time does not work for him unless the committee meets at a different time. The others wanted to appear, but wanted more notice to give them time to prepare. They asked for more time.
For November 27, I can confirm that Ms. Luelo will be here, as will someone from the RCMP.
The Canada Elections commissioner suggested that she not be invited, saying that the subject of the study is not really related to their work.
I was unable to reach the data protection commissioner for Ireland, despite sending emails to her. So I cannot confirm her presence.
For November 29, Google refused to send us any witnesses. In addition, I was unable to contact someone from Reddit. For the second hour, however, we did receive a confirmation from Leadership Lab, who will be sending two people. Further, Matt Malone confirmed his attendance, along with another person.
As to the witnesses who were invited to today's meeting and who asked for more time to prepare, I can invite them for December 4, if the committee so wishes.
