Sure. Thank you. I'd be happy to.
Again, although we collect metadata, it's very much limited in its use to our existing mandate, which is foreign intelligence collection and cyber-defence. The restrictions we have around that is to understand global networks to find foreign targets. We're not using it to target Canadians or anyone in Canada for our intelligence-gathering activities unless we're assisting CSIS and RCMP under a court warrant. Otherwise our activities are aimed at foreign targets outside Canada to collect intelligence against priorities established by the government.
We have to have measures in place to protect the privacy of that information. That's what the commissioner reviews carefully and reports on. He has done six reviews over the years by three different commissioners of metadata and found those activities to be lawful.
