Every time I think I'm just about "done", some new lead falls into my hands and confuses me. Specifically, there seem to have been so many different sanctioning organizations, driver's associations, and regional clubs. Different races seem to use different racing classes. I wish I had some sort of chart to show how they all relate.
Here's the latest conundrum... in a BMC magazine ad that Mike Adams found and forwarded to me just this morning:

(you might notice that the photo shows Pease's MGB in mid-1963 trim, which was quite different...)
As you see, this ad congratulates Pease with having been named "1964 Driver of the Year" by both the "Canadian Racing Drivers Association" (CRDA) and also the "CRCA".
CRCA? Never heard of them! What does that acronym even stand for? Could BMC have meant "CASC" (i.e. "Canadian Automobile Sport Clubs")?
Frankly, I'd be very appreciative if someone would concisely explain the relationship or difference between CASC and CRDA. I know CASC actually sanctioned races and that they had regional and local clubs under their big umbrella... but did CRDA also sanction races? Did CRDA give awards based on who won CASC races? Did CASC and CRDA use the same racing class system? Did CASC and CRDA both award "Driver of the Year" titles? Were these titles based on some sort of points system, or a popularity contest, or what?
ANY insight at all about Canadian sports car racing in the sixties will be greatly appreciated.
