It's not a question of Transport Canada approaching you. When they issued their exemption, they created a three-year timetable: you've got to do this by this, or we're going to pull your operating certificate.
So the operator got their brain focused and met the first milestone, then they organized themselves to meet the second milestone, and then they will do whatever they have to do in the third year. Then Transport Canada will go, click, the regulations are on.
These are for existing operators, not for new people who started today. I don't know much about that.
