Since the introduction of stricter gun laws in 1991, there has been a 65 per cent reduction in homicides by long guns, Statistics Canada data shows. The reduction in homicides involving any type of firearm was 37 per cent.

Statistics Canada released a report on Oct. 26, 2011, on homicides in Canada in 2010. That year, there were 170 shooting homicides, about 32 per cent of all homicides. The total homicide rate fell to its lowest level since 1966 (1.62 per 100,000 population).

From 1995, when the firearms registry became law, to 2010, there was a 41 per cent reduction in homicides by long guns.

During those years, the cost of establishing the registry was more than $1 billion. The Harper government campaigned on getting rid of the long-gun registry and now it says it also intends to destroy all the information about long-gun owners that has been collected.

Gun registry information is used by police across Canada more than 17,000 times per day.

Those statistics and others will be part of the debate over scrapping the registry. Here's a look at the numbers.

The cost per survivor admitted to hospital was approximately $300,000. That number was adjusted for inflation to provide an estimate for 2011.)

1995: $2 million (government estimate of total cost of $119 million for the registry, minus registration fees)
