It may not exactly be a major blow against the smuggling of guns used in crime, but an operational 9mm Sten could be pretty damned dangerous. the AR-15 has been banned. It's the wrong side to know if it's fully auto as the selector is on the left side, and an ambidextrous safety hasn't been installed. I don't recognize the part directly below the AR, but it doesn't look like an auto sear. As to the rest it's still illegal importation of firearms, and pistol purchases have been blocked for quite a while now. it appears to be a good arrest, if not something that will delay anyone in Toronto who is planning a drive-by.
