It seems there are many more restrictions placed on the Canadian citizens in order for them to be able to own guns.

The Firearms Act
The 1995 Firearms Act had three main public safety goals: to deter the misuse of firearms, to control access to them and to control specific weapons. The national firearm registry will make it easier to trace guns used in criminal activity and to return stolen guns to their owners. The licensing requirements, which include extensive background checks and a spouse's signature on the application, are designed to prevent those with a history of criminal behaviour, mental illness or spousal abuse from legally owning a gun. To prevent loss of life through accidental shootings, the law requires an applicant for a firearms license to take the Canadian Firearms Safety Course and pass a test demonstrating a basic understanding of who to handle guns safely and the legal responsibilities of firearm ownership. It also requires that all firearms be stored unloaded and locked.
The 1996 amendments to the Criminal Code created four-year minimum sentences for violent crime committed using a firearm, including attempted murder, manslaughter, robbery, sexual assault with a weapon and kidnapping.
Program Statistics
In the 18 months between December 1, 1998, when the Firearms Act came into effect, and June 1, 2001, 2 million Canadians, almost 90% of the estimated number of owners in Canada, had participated in the licensing process. Some 3,000 firearms licences had been refused or revoked, a figure 27 times the total for the last five years of the previous system. A toll-free telephone hotline established to allow spouses of license applicants and others to express concerns or report crimes committed with firearms had logged more than 22,000 calls.
