An increasing popular proposal for reducing the incidence of suicide h
as been restricting the availability of methods for committing suicide
. Countries differ in the most popular method for suicide, but firearm
s are the preferred method in some, including Canada and the United St
ates. An opportunity for studying the effects of legislative gun contr
ol laws on their use for suicide is provided by Canada's Criminal Law
Amendment Act of 1977 (Bill C-51). This paper reviews the studies on t
he impact of this act, exploring such factors as age and sex. Research
on homicide and accidental death are also presented. It is concluded
that, although gun control may have an impact, further study is warran
ted.
