National Defence committee  Absolutely. When we have an unknown track and we think it might be a balloon, we first of all have to identify it as such, which is challenging, given our domain awareness issues. In other words, our radar coverage does not go far enough out over our coast and over northern Canada.

National Defence committee  Good morning, Mr. Chair and members of the committee, and thank you for the opportunity to testify today. I am Lieutenant-General Blaise Frawley, Deputy Commander of the North American Aerospace Defence Command (NORAD), headquartered in Colorado Springs. As Deputy Commander of NORAD, my role is to support General Gregory Guillot, Commander of NORAD, in the execution of our binational command's missions, namely aerospace warning, aerospace control and maritime warning.
