First, we have current capability through the North Warning System and other infrastructure, the radar station network that was built between 1986 and 1992. As this forum knows well, new and accelerating threats are challenging that antiquated technology. Therefore, investments have been made in NORAD modernization, in both Arctic over-the-horizon as well as polar over-the-horizon capabilities.
I will also say that integrated air and missile defence is exceptionally topical and important. When we talk about visualizing a Canadian continental shield, in the United States they have the U.S. “golden dome”. Generally speaking, this is a system of systems that allows you to sense and react to incoming threats that eclipse our North Warning System, but for which the investments made, and soon to be realized, are going to position us to better deal with those accelerating threats.
