Some interesting information in a Star Article here in Toronto. We have some pretty strict gun control laws in Canada.

Broken down further, the crime gun statistics indicate many criminals are arming themselves with starter's pistols, air pistols, replicas, toy guns, paintball guns, cap guns and flare guns. In fact, more than a quarter of the recovered guns are not normally considered lethal weapons.

More than half of the total number of firearms seized by Toronto police last year were considered "non-criminal," coming into their possession through a variety of means, such as a family member turning in an antique rifle after its owner dies or through a gun amnesty.
So it sounds to me like only about 25% of the guns recovered were actually considered Illegal Lethal weapons.

I think we are on about our 5th or 6th gun related crime here in TO for this year. At least 2 murders.

Another point
The statistics also show that Toronto police are only seizing a small number of the estimated 5,000 firearms reported missing each year across Canada. The task force recorded just 40 stolen firearms recovered as of Dec. 18.
Which seems to support xld's claim. Those responsible gun owners are having thier legimate weapons stolen from them, and then used for crime.
