That's a really good question. The only benchmark I am aware of is one in the area of school psychology. We know that the greatest return on investment when it comes to mental health is with children.
The benchmark is about one psychologist for every thousand students. The European Federation of Psychologists' Associations guesses that it should be about one to 1,500. In Canada it really is all over the map. Half the psychologists in the country are in Quebec, which is interesting, and in the rest of the jurisdictions it's one to 3,000 or 4,000. In rural and remote areas, it's about one to 28,000.
My answer on whether there are enough psychologists is that I'm not sure we have a clear benchmark in Canada. But we do know that we're the largest group. There are four times as many psychologists as psychiatrists licensed to practice.
