The history is that Canada used to have "compulsory licensing" for patented drugs. Anyone could manufacture a patented drug in Canada and pay a ?6?% or whatever royalty to the patent owner and they just had to deal with it.
Over the years, first 4, then 10 years of exclusivity were provided to the patent owner.
Then the WTO came along, and presently, everyone has agreed to ~20y exclusivity and charge/pay the median price of OECD countries before it's a royalty-free free-for-all.

Canadian generic drugs today aren't usually cheaper than US generics, except where patent exclusivity mismatches.
