A judge has extended the short-term injunction blocking the federal government from dismantling the long gun registry.

Two NDP MPs broke party ranks to vote with the government in the final House of Commons vote on scrapping the long-gun registry.

The Quebec government has filed for a court injunction to prevent Ottawa from destroying data in the federal long-gun registry.

As it prepares to destroy millions of long gun records, the RCMP says the Conservative government's decision to scrap the registry will make it tougher to trace firearms used to commit crimes.

The RCMP commssioner has reminded chief firearms officers that the will of Parliament is that "any form" of a long-gun registry be abolished, and that should be kept in mind when enforcing rules on store owners.
