I think this is one great picture of our old Ottawa's Union Station from This was the waiting area? You can see the stairs going up to Rideau St, and the tunnel that took you over to the Chateau Laurier.
Found this photo at the Ottawa Main Library - I remember buying a few dresses there in the late 60's at a good price. Fashion Dress Shop at 159 Rideau, corner of Dalhousie. You see the Windsor Smoke Shop on the corner, and if you look on the side of Dalhousie you can see part of the sign of the Swedlove Furniture Store
