Canada-China Relations committee  The Canadian Security Intelligence Service was involved and informed of the activities that were under way from the outset of the cases that are under way. As disclosed in the documents, they were engaged and aware, and we were working together as of August and September 2018, so—

Canada-China Relations committee  Yes, of course. Canadian Security Intelligence Service members have tools available to them under the act that only they have. They were involved in the fact-finding and the investigation all the way along. It wasn't until the later stages of that investigation that they were able to obtain the information that informed that June 30 letter.

Canada-China Relations committee  The individuals who hid their activities and undertook clandestine collaborations have been terminated, fired from the public service and the like. The—

Canada-China Relations committee  We will return to the committee with that information. I don't have it at hand.

Canada-China Relations committee  When we use the term “national microbiology lab”, we're referring to a complex of buildings that has both secure and public facilities. I'll turn to our two security officers to talk about the policy.

Canada-China Relations committee  I'll defer to Dr. Poliquin with regard to the procedures at the lab.

Canada-China Relations committee  I'll turn to our chief security officer to talk about the procedures.

Canada-China Relations committee  Our security processes and procedures have been enhanced across the board. We have in place additional policies around security clearances, around access controls and around the types of visitors and students who are able to access the lab, and those policies are much more stringent than they were at the time, which would provide—

Canada-China Relations committee  All I can say is that it's a hypothetical question, Mr. Chair, because the collaboration—

Canada-China Relations committee  Under the current policies, there would have been two additional layers of review for that collaboration, which was in fact approved in November 2018, although the shipment took place later. The collaboration was approved much earlier, in line with the policies at the time. The difference now is that it would be approved by two additional layers of review.

Canada-China Relations committee  I think the committee is aware that there is an ongoing RCMP investigation, and I would have to refer the committee to my colleagues at Public Safety Canada and the RCMP in terms of their investigations and any work that's under way there.

Canada-China Relations committee  I'm not aware of the details of their investigations, so I will have to refer you to Public Safety Canada.

Canada-China Relations committee  The policy on security clearance is set by the Treasury Board Secretariat. It is irrespective of nationality.

Canada-China Relations committee  I'm going to defer to Dr. Poliquin about the processes for restricted visitors at the lab.

Canada-China Relations committee  I would say that the policy on visitors restricted their access to areas in line with the clearances they had, so there would have been no access of visitors to restricted level 3 and level 4 labs.
