Some armories were completely torn down. The 3 Field Engineer Squadron of Ottawa used to meet at Lees Avenue, right on the Rideau River close to the now Ottawa U campus. I have great memories of weekends building Bailey Bridges in the yard and taking assault boats up and down the river. Not a real picturesque complex, like many others such as the Cartier Drill Hall of red brick Gothic Revival style, just simple Quonset huts and garages, but still we had a drill hall and great mess dinners there. All gone and torn down in the early 1990's, just an empty field. The giant old oak is still there, where we as raw recruits would congregate, climb, and chat during bridge building breaks.
If anyone has any pictures of the armories, I sure would be grateful to see them.
