I worked for the government and we used rental cars. Health Canada isn't going to drive their own cars to Lakeshore from Ottawa. They likely flew in and rented cars, as any other government agency would do.
And no, I didn't inspect how many cameras and lights there were, and I didn't inspect the ventilation and HVAC. It would've been quite difficult on my drive-by to inspect the ventilation and HVAC, but maybe you'd find it easier to do if you drove by.
And it was several people, not a guy in a suit. But you know what, maybe you're right. Maybe it was Chaaban's money man. You clearly know more than anyone else on the subject.
