Mark,
The Port of Montreal have(or had)one up on a wooden platform along the pier road in the east end of the harbour.Used to see it everyday when I was a marine cargo surveyor.It was painted blue(the port's vessel colors).It looked like it was used in a maintenance role but can't confirm if it is still there.Maybe contact Frank Martini at the head office.He may be able to help you.
