Thank you.
As you may know, at one of our last meetings we did talk to the folks who actually provide these devices and the technology. In the past five or six years that I've been a member of Parliament, there have been a whole lot of technical devices, which even our chair was playing with—I mean, working with—before the meeting.
I guess my question would be this. We've heard some of the problems concerning a person wearing devices going into a subway and things like that. I wonder if your previous study was able to determine—and I'm glad you mentioned the geographic realities of Canada—if there is a difference between the efficacy of using these devices between urban and rural areas. There are no subways in any of the communities I've lived in. It's mostly outdoors and there are not a lot of high-rise buildings.
Is there any difference experienced there? Could you expand on that?
