Agreed, it appears to be a Road Racer for all the reasons stated by Clubman, plus the small diameter of the seat post. The latter is the best way to distinguish a Road Racer from a Flyer (or Custom Built Professional Race). Since the Road Racer uses plain carbon steel, it has thick tubes and uses the the standard 7/8" diameter seat post, which the OP's bicycle appears to have. The Flyers used stronger chromium-molybdenum tubing which allowed for thinner walls and used a larger, 1-1/16" diameter, seat post.
Regarding the colour, it may be a repaint, but I've had lengthy discussion on this with an owner who has one in the same colour. During this era CCM would do special orders with custom paint and there were four distinct greens available based on their touch-up paint lists. Unfortunately, I've never been able to determine the exact tone of these various greens, outside of the Boy Scout Green. Consequently, there is a possibility that this is custom, OEM paint.
