It's quite simple. The Health Canada inspection is not a cursory walk through. This is for selling a pharmaceutical , not a plant.
All systems and protocols are reviewed . One CEO of a company that received it's license said it took 2 days to go through everything.
My old man worked for Ag Canada in Leamington. He had his own gov't car . Things may have changed but I doubt Health Canada rents cars . And if there was a government inspection there would be no contractors hanging around.
Complete property surveillance is required ,including the perimeter. You drove by, how many cameras and outdoor lights are there ? How's the ventilation , HVAC look?
A guy in a suit. Could be anybody . Insurance, accountant ,security , Chaaban's money man.
