The drop bar frame looks like it has a CCM chain ring sprocket. With the lug frame and other details, it does appear more foreign (to me) than old; (one piece crank?). There may be a CCM following up North (of here), but that bike too looks like your basic rider project, yet nicer (and shorter) than a plain diamond frame.
The original red paint may have seen some harsh Winters, (not to mention snow-filled Canadian Autumns and Springs, eh).
Looks like the head tube may have sported one of those "skeletonized" CCM head badges.
I was traveling through Calgary a few years back, in the middle of May, and it snowed!
