here's a range of info about AD years, including Canadian production ... and here's numbers pre-48 ... I've seen a site with more AD years but can't recall where now, maybe Tims?

I heard sometime ago GM had a fire in a plant where they lost a bunch of archived material, but I also think they didn't keep very good records of production breakdowns beyond "light/heavy" before the 60's
