To my knowledge the 112 ft Fairmiles were not built in Montreal. The Canadian Power Boat Company, built the Scott-Paine 70ft MTBs and RL (rescue launch)

in the pictures you can see them. in the one picture taken from behind you can just see the small iron drawbridge for the road beside the Lachine Canal The canal is right on the other side of the bridge. Boats leaving the basin would have had to make a fairly sharp turn into the canal.. location is actually not far from the current Atwater Market

go to google earth, and type in 4000 St Patrick then take the little man and put it on the red dot to get street view,. its actually a bit east of the red dot.
its a rather run down looking white building ..the gate has the number 4000 on it..this would have been the little channel from the boat basin leading out into the canal.. I suspect the original road would be where the bike path is today.

the other photo is from Camp Bouchard I took about ten years ago. these were the concrete remains of small filling rooms. if you look you can see the two side walls..the fourth back wall would have been the wooden exterior wall of the building covering the various filling chambers..the idea being that with the three concrete walls, the front inside the building and the two side walls, if there was an explosion it would go up through the roof and out through the back and not take out the adjoining chambers or the rest of the operation inside the building,

The various buildings were spread far apart from each other. the operation was huge and covered a couple of sq km or more.. At the time when wandering through the brush, you might come across a fire hydrant.
