This report outlines a comparative study of firearm injury prevention initiatives in five countries, including national gun buybacks, amnesties and weapon destruction programmes. It was commissioned by the Government of Canada Joint Federal/Provincial Commission into the April 2020 Nova Scotia mass casualty.

The report argues that the Australian experience with firearm regulation provides important lessons for other jurisdictions with high rates of gun violence. This example demonstrates that taking a public health approach to firearm injury prevention by reducing access, strengthening regulation, and engaging the community can reduce gun deaths. Along with emerging evidence in New Zealand after the Christchurch mosque massacre, it also shows that a mass shooting incident can be a galvanising event for a country to improve policies on a wide scale.
