Thank you, Chair.
Thank you to all the witnesses for coming in. It's certainly important to talk about some of the issues we've heard already.
Mr. McDonald, just on your point, I actually just recently announced a number of dollars that went into funding right across my riding. There are probably at least a half-dozen different crossings that are being upgraded for safety purposes, which is extremely important, I think, for the communities, for the citizens who might be using those roadways. That's an important aspect.
Mr. Davies, in your comments you talked about how we have infrastructure in place to communicate with government at all levels, private sector, and operators of critical infrastructure—obviously including transportation. Could you maybe give us a little better feel for what “critical infrastructure” might be?
