Thank you very much, Madam Chair, and thanks to our witnesses for joining us today for this very important study.
As you noted, Ms. Fox, this issue has received significant public attention in the past year, certainly as a result of the tragedy that took place with the Humboldt Broncos and, as you pointed out, the more recent accident with OC Transpo. I've already learned something through your opening remarks in terms of the role of the TSB when it comes to road accidents and bus safety in particular and what mandate the TSB has in those circumstances.
I am going to drill down just a little in terms of trying to understand what it is that we could possibly glean from your time with us today. I know that we are required to wear seat belts on airplanes during takeoff, landing and taxiing, and during turbulence. I'm just wondering if you could tell me who created that rule. Is it a law or a regulation? Was it the airlines or was it through Transport Canada?
