Yes. I co-authored a book called The Global Gun Epidemic with Vic Sidel, who is past president of the American Public Health Association. What it shows is that among industrialized countries, on a global basis, there is a very strong relationship between the availability of firearms, suicide with firearms and overall suicide. You can see that it's particularly pronounced even within Canada when you look at differences between, for example, urban centres, rural centres, the east and the west, and I have to say, with respect, that recent studies on suicide by military veterans do mention the availability of firearms being a factor that needs to be addressed.
The availability of lethal means is associated with what we call suicide completions, which means 93% of suicides attempted with a firearm will result in death, versus attempts by other means. I think the evidence is pretty unequivocal that the availability of firearms is associated with suicide rates and that legislation that reduces the availability of firearms to people who are at risk to themselves or others is associated with reductions in suicide.
If we look at Canada's track record, we see that after Bill C-68, we were on a trajectory that was very comparable to what we saw in Australia. Then when the laws were relaxed, we saw that trend reversed.
