Canada Bans Assault-Style Weapons

Canada has implemented a ban on 1500 models of assault-style firearms, aiming to eliminate weapons designed to kill many people quickly. The ban includes prohibitions on purchase, sale, transport, import, and use of these firearms. A two-year amnesty period is provided for gun owners to comply, along with a planned buyback program. This decision follows a tragic shooting in Nova Scotia, marking the deadliest in Canadian history.
