Thank you for your question, Mr. Shipley, and for your kind comments.
The Canadian footprint in the NORAD enterprise in the U.S. is about 300 personnel—125 personnel in Colorado Springs and the rest spread among the regions, the sectors, and the AWACS. They operate U.S. systems, just as we have Americans in Canada operating Canadian systems.
The systems in place in some areas are particular to the NORAD mission and are unique in the world. I have in mind our NORAD radars in Thule, in Cape Cod, and in Clear, Alaska, and so on. There are Canadian personnel operating at those sites as well.
As with anything you do differently, training is required because of the unique relationship and mission. We're the only two countries in the world so confident in each other that we have decided to share responsibility and accountability for three defence missions.
