Nice to see yet another Edmontonian here...
The bike does not look too shabby but the price seems a little high... I can usually help folks build up a bike like this for under 100 dollars at our shop here (EBC) and use better parts and mid 70's CCM bikes are pretty pedestrian.
If you wanted a nice ss bike I would really lean toward a nice Japanese frame which will be lighter and probably come with better bits.
This is not to say that I haven't put some considerable work into my own really old CCM bikes... if you see this old beater around town it would be me... cause there's only one like this.
