Our use of metadata, we use it based on the directions from the minister for three things.
One is to understand global communication networks, so we use it to analyze networks so that when we're searching for a foreign target, it helps us to find where our best chance of success is in identifying targets in a sea of billions of communications.
Two, we use it to make sure that we're actually targeting a foreign communication and not a Canadian communication.
Three, we use metadata to help us detect and identify cyber-attacks against government systems and the information they contain. We can only use metadata either to understand global networks and analyze them, or to define our foreign targets. We don't use it to identify or target Canadians.
