The federal government is calling the ruling a victory.
"The will of Parliament and Canadians has been clear. We do not want any form of a wasteful and ineffective long gun registry," Public Safety Minister Vic Toews said in a statement.
The Superior Court had heard a motion from the Barbra Schlifer Commemorative Clinic in Toronto for an emergency injunction to prevent the destruction of data from the federal long-gun registry.
Justice D.M. Brown refused to place an injunction on the government's decision to destroy the information still being held in a computer database in Ottawa. The files include the names, addresses, phone numbers and registry numbers of all long-gun owners in Canada, dating back almost 20 years.
Canadian gun owners and firearms advocates are celebrating the decision.
