In terms of actual number of suicides, the numbers, as you correctly state, are increasing. In 1991 there were 3,593 suicides in Canada. In 2008, in the most recent number, there were 3,700. As you also realize, the population in Canada has increased substantially since 1991, so the rates have gone down while the raw numbers have increased.
The key question, of course, is the methodology, but you have not asked me that.
