It was quite peaceful that night. Maybe one factory operating and a few security guards on patrol. I had encounters with security guards and police when I photographed the oil refineries in Sarnia a few years ago, so I try not to draw too much attention when I am in these places.
But this is Mississauga, so the security is probably more worried about young men racing their modded Honda Civics behind the warehouses. I saw a lot of this when I photographed on different night. A lot of noise and smoke not from the factories.
