Canada's government is set to announce a ban on assault-style weapons following a deadly shooting in Nova Scotia this month that killed 22 people. Officials told The Associated Press on Wednesday that Prime Minister Justin Trudeau's administration will announce the ban before the week's end, though the key provisions have already been decided by his Cabinet. Among the weapons set to be banned include the AR-15 and the Ruger Mini-14. It wasn't initially clear whether Canadian citizens who currently own such weapons will be required to turn them in.
