Every section in Canada is responsible for their members, so that would be mostly every province. Every province keeps a database on who participates and monitors it. If you go past the two-year mark, you would get a notice and you would be able to recertify. If you don't recertify at that time, you'd have to start at zero and come back and take the black badge course again, and you'd lose your membership.
