The Canadian government is introducing legislation to implement a “national freeze” on handgun ownership and prevent people buying and selling handguns.

“The day this legislation goes into effect it will no longer be possible to buy, sell, transfer or import handguns in Canada,” Prime Minister Justin Trudeau said on Monday.

If passed, the freeze on handguns is expected to come into force in the northern autumn. Canada’s public safety minister has tabled regulatory amendments in parliament to ensure it can be implemented swiftly, according to a ministry statement.

The killing last week of 19 children and two teachers at an elementary school in Texas in the US has fed concern about gun violence worldwide. Canada already has significantly stronger gun ownership restrictions than its neighbour to the south.

Canada banned the sale and use of some 1500 models of assault weapons, like the AR-15 rifle, two years ago. Speaking alongside Mr Trudeau, Public Safety Minister Marco Mendicino confirmed the “imminent launch of the initial phase” of a program to buy back and compensate owners of such weapons.

The new legislation also proposes taking away the firearms licenses of those involved in acts of domestic violence or criminal harassment such as stalking.

The legislation proposed stricter sentences for gun smugglers and traffickers, and aimed to provide law enforcement with new tools such as wiretapping to stop gun crime, Mr Mendicino said.

The government will also require long-gun magazines to be permanently altered so they can never hold more than five rounds, and will ban the sale and transfer of large capacity magazines.

“Other than using firearms for sport shooting and hunting, there is no reason anyone in Canada should need guns in their everyday lives,” Mr Trudeau said.

Canada’s rate of firearm homicides is 0.5 per 100,000 people, compared with the US rate of 4.12, according to a 2021 analysis by the University of Washington’s Institute for Health Metrics and Evaluation.
