Justin Trudeau says the federal government is launching the long-promised buyback program for what he has described as “assault” or “assault-style” firearms.The buyback program is part of a suite of new gun control measures promised by the federal Liberals in the 2019 election campaign, and follows the announcement of an executive order last May that changed the classification listings to prohibit roughly 1,500 “assault-style” weapons.While terms like “assault-style” and “assault rifle” are not legal classifications in Canada, they are frequently used colloquially by gun control advocates and the government to describe the type of high-capacity, quick-fire guns targeted by the ban.Automatic firearms are already prohibited in Canada, as are.
