That's a very important question.
We rely on the national security agencies, along with the Canadian Forces intelligence command, the foreign intelligence unit at Global Affairs Canada and allies to help us assess the depth and persistence of foreign interference in Canada.
As we said, it's not new and it's not restricted to or targeted at Canada in particular.
We use a number of tools and tradecraft, which certainly we're not going to discuss publicly. The collection of intelligence and the analysis of that intelligence in its totality—not the individual pieces—and understanding the veracity of it—whether or not it's reliable and whether there is conflicting or contradictory information—help build that picture.
Certainly the activities of proxies play a role in that.
