Thank you for the question.
A back door, the way that I understand it, is the systemic vulnerability that we've been talking about in relation to part 2.
Lawful authorizations, as our colleagues from CSIS and the RCMP have said, are obtained from the court. This is when police or national security is required to get a warrant. There are certain requirements to obtain that warrant in terms of evidence. The issue is that we have many of the tools already in the CSIS Act and the Criminal Code that allow our authorities to gain access. The problem is that when they go to the service provider, the service provider cannot allow them access.
