I'll answer briefly, Mr. Chair.
One of the great enviable things about the Canadian approach is the seamless integration of CSE, CSIS and Defence in this domain. That's not to say that no challenges remain, but it's certainly an example of how within government the cohesion between those three entities allows Canada to lead and innovate in ways that may be unexpected.
As far as collaboration with our partners in the States goes, we have folks embedded in their cyber command. The collaboration between CSE and the U.S. agencies as well as Defence for our specific role when we're outside of the country continues on a day-to-day, week-to-week and minute-to-minute basis.
It's a challenging environment, particularly in terms of attribution of who's doing what, and therefore elevating other tools or instruments of national power to act, and it is a growing domain.
