OTTAWA, May 1 (Xinhua) -- Canadian Prime Minister Justin Trudeau on Friday announced a ban on some 1,500 makes and models of military-grade "assault-style" weapons in Canada.

Starting Friday, licensed gun owners will no longer be allowed to sell, transport, import or use these sort of weapons in the country.

"Effective immediately, it is no longer permitted to buy, sell, transport, import or use military-grade assault weapons in this country," Trudeau said at a press conference in Ottawa Friday morning alongside with Deputy Prime Minister Chrystia Freeland, Justice Minister David Lametti, and Public Safety Minister Bill Blair.

Trudeau cited numerous mass shootings, from Ecole Polytechnique in 1989 to the killings in Nova Scotia last week, as the reasons for the ban.

Stricter controls on firearms were also a promise in the Liberals' election campaign platform last fall.

Trudeau also said there will be a two-year amnesty period for people who already own these firearms to comply with the ban. He promised to pass legislation in the coming months to provide "fair compensation" for people who own these firearms.

By April 2022, all Canadians must be in compliance with the law, Justice Minister David Lametti said, adding that gun owners that have not disposed of their banned firearms could face criminal sanctions under the criminal code.

Firearms owners may return the firearms to the manufacturer or export them as part of a sale between now and 2022, according to Lametti.
