I should note that stakeholders are very supportive of the use of safety management systems. It's a way for them to systematically manage their safety environments, and it's something they take very seriously as well.
Canada has been a leader in the introduction of safety management systems. We were one of the first countries to do so internationally, and right now all our carriers carrying 20 passengers and more are required to have safety management systems as part of their regime.
We are currently investigating whether or not to extend that requirement to those carriers carrying between 10 and 20 and then 10 and fewer. One of the issues we have to deal with is whether or not the industry has the capacity to do that at that level. Obviously, a small airline operation doesn't have the same capacity as Air Canada to implement a system such as that. So we have to ensure that the system is scalable enough to allow for it to be implemented.
That being said, many of the smaller carriers have implemented safety management systems on their own, just because they see it as a good management practice.
This is not endemic to the airline industry; indeed, we have safety management systems in the marine industry and in many industries other than transportation. In fact, safety management systems came about in the chemical industry as a result of the Bhopal disaster in India.
