This picture circa 1960 shows the NRCan complex under construction. That’s Commissioner’s Park in the foreground, Carling Avenue runs through the caption. Running parallel to Carling across the top of the picture is the old railway tracks, the Queensway being not yet built.
What is sorta fun, if you are inclined that way, are the number of bridges over the railway tracks. From left to right, you can see Rochester, then Booth. The next one beyond Booth is LeBreton (running immediately behind the new office towers), and a bit further east, up above the escarpment is Bell Street. If you squint hard enough where Bell goes over the railway, on the north side, you can see Bell Street United Church, which is still there.
Cambridge also had a bridge over the railway tracks. In the photo, it looks like it was a hump back arched bridge, although that may be a trick of the shadow. I’d love to see some photos of those bridges.
Also quite visible to the far top right is the distinctive curve in Imperial/Chamberlain Avenue where it leaves Bronson and wiggles around behind the school board warehouse that still stands at the corner of Bronson and Queensway, although it will shortly be demolished to make way for more Queensway ramps.
This air photo from 1958 shows roughly the same area:
