It is regional: It's provincial and it's territorial. That's the way it's.... Just to be clear, dental assistants are different from dental hygienists. Dental hygienists usually require post-secondary education—university or college—but dental assistants usually spend less time in school than do dental hygienists. We estimate that there are probably 26,000 to 29,000 dental assistants in Canada, but they're unregulated in Ontario and Quebec. There are about 20,000 certified and licensed, and for hygienists it's about 30,000. There's probably a bit of a manpower challenge with both, but certainly, dental assisting is critical, because I know first-hand that some dentists can't adequately work without a dental assistant next to them.
Dr. Burry, I don't know if you want to elaborate on any of that.
