The Trudeau government is ready to introduce legislation as early as next week aimed at strengthening gun control.
The long-promised bill would complete last spring's ban of many firearms, propose stricter storage provisions and target gun smuggling.
The government outlawed a variety of firearms by cabinet order in May, saying they were built for the battlefield, not hunting or sport-shooting.
The ban covers some 1500 models and variants of what the government considers assault-style weapons.
