Again, I can only speak to the recommendation that we made following the OC Transpo-VIA Rail accident in 2013. We recommended that Transport Canada should enact crashworthiness standards for commercial passenger buses that would fill the gaps that we identified with respect to frontal and side impact crush and rollover protection. Transport Canada is slowly working its way through that recommendation.
But, yes, as the RCMP sergeant has indicated, the crash dynamics are very different depending on whether it's a frontal crash or a side crash, depending on the mass of the vehicles involved, depending on their speeds and so on. Really, it's up to the experts to analyze those situations and determine when it is best to require seat belts, for example.
However, we believe that, overall, the actual structure of the bus needs to be reinforced, even though it's a large vehicle and it may be larger than anything else it meets on the road.
