Thank you, Mr. Chair.
Thank you to all the witnesses for your helpful testimony here this morning.
I'd like to follow up on a couple of lines that my friend Mr. Comartin began. I must premise my remarks by saying his experience is much different from mine, I suspect. He lives in Windsor, and I live in Edmonton. I live a long way from the border. I travel to the United States very infrequently, and almost never by land. I know nothing about this, so if my questions appear to be of a general nature, forgive me, but I'm sure they'll be easy for you to answer.
We hear all the time that between the United States and Canada we have the largest undefended border in the world. I have some knowledge of the geography, of how many kilometres and miles it is, and there are great areas with little population. I'm thinking of the Great Lakes in particular, and in the west we have mountainous terrain between Montana and Alberta and between Washington and British Columbia. In Saskatchewan, where I was born, there are very sparsely populated areas south of Estevan and in southern Saskatchewan. I think you made reference, Mr. Rigby, to barriers being installed in Quebec. What percentage of the border is barriered, as opposed to barrier-free? I appreciate that you might not know, but you might make a guess.
