On May 1, Canadian Prime Minister Justin Trudeau announced a ban on assault-style weapons.^[1] The ban affects some 1,500 different types of firearms, including weapons such as the AR-15. The ban was made law by an order through the Governor in Council, thus circumventing Parliament; the Canadian government also took advantage of the pandemic to implement the law quickly and without notification to trading partners or to the World Trade Organization (WTO), as required by certain notification obligations.
