Apparently, regarding 20mm or larger bores, it has "been clarified" that it does not pertain to shotguns.
But regarding the rest of the ban, what a crock of s_ _ _ t. And apparently there was a poll taken in major cities where 62% of the people felt the ban does not go far enough citing that there should be a ban on all guns. We are in deep trouble when the majority of citizens have been brain washed by false, inaccurate and politically motivated information. But this is what happens when, over the years, more and more people got out of hunting or shooting and never introduced their children to the true facts. As far as I'm concerned, firearms and hunter safety should be taught in schools. But that will never happen.
IIRC teaching firearms safety and use in schools is part of the Sask Wexit Party platform. The solution is for the West to leave.
