Hey Mark,
My father served at Camp Bouchard after the war and he had fond memories of the courses he attended there. He used to fly to Camp Bouchard in a RCAF DC3 from Sherbrooke. They landed in Cartierville airport now closed and then boarded a Jeep or other transport to Camp Bouchard.
I regularly overfly Camp Bouchard by plane ( my Cessna) and chopper ( Griffon today's RCAF ) and there are numerous remaining buildings and ammunition bunkers . Next door there is a testing oval racetrack were there were safety trials of cars by Transport Canada that is still being used by someone .
There are still munitions plants in Montréal. Grenades , ammunition , and other misc are made . Don't forget that the country's largest military depot is in Longue Pointe.. , Montréal. For example ,there a more Leopard tanks in Longue Pointe than anywere else in Canada. Recently ( in the last years ) a lot of 1000' s of Inglis High Power 9mm pistols were drawn from stores in Longue Pointe for service in a Far East country i will not name . Brand new in the box never fired dated from 1945 . From first hand experience they shoot very well.
Montréal's economy is still very much military oriented. From F-18 refurbishment, to F16/ 18 landing gear manufacture , Simulators , comms, sofware etc....amongst other things.
Cheers !
