In aviation, we have the International Civil Aviation Organization, which is the overarching organization to which Canada is a member, having signed the convention. On the maritime side, it is the International Maritime Organization.
Both of those set overarching standards for standards in aviation and marine. Both have required in Canada, in the case of air for over 50 years, and in the case of marine, since 2002, voice recordings. Video is not yet a requirement. It is something that is being discussed, currently, at the international level.
However, there have been recommendations, and in fact, the TSB has made recommendations with respect to the implementation of video recorders in air as a result of the Swiss Air accident back in 1998, and in rail as a result of the Burlington accident in 2013. In the case of rail, there is no overarching international organization, and that is why each country is left to its own to determine how to proceed in these cases.
