It is amazing to me that there is so much discussion about this issue when the behavior of lawyers and prosecutors is so well known and with so much historical precedent. In every area of law, not just pertaining to firearms. There is even the expression "The letter of the law". Lawyers argue and win based on where commas get put. Nothing else matters but the actual wording.
It may not be the intent of Trudeau today. The RCMP may have an opinion about it. Blair may have tweeted. But if it gets in front of a judge, and you can be sure some overzealous cop and prosecutor will make that happen one day, then the merits of the case will be based on exactly what the law says and not what SAAMI or the RCMP or Bill Blair think. The only way to make this not be the case is for the government to change the wording of the OIC or to pass a subsequent law rendering that portion of the OIC null and void because it's been replaced with updated wording.
Just because the above is true, doesn't mean I will do anything different regarding 12 gauge shotguns with chokes. I will be ignoring the prohibition and using them as i always have. And if that means one day i get charged, so be it.
