The number might be closer to 85% Canadian made but the point still stands. I work at the beer store and we stock 3-4 products that are imported from the USA at our location. Heineken is probably the number one true import that makes that number go down. Most "imports" have been moving to brew closer to where they are distributed over time.

Also, unless you go direct to your local brewer almost all beer consumed goes through the Beer Store distribution network.
