Across much of the US and Canada, words like "therapist" and "psychotherapist" are unregulated titles and practices, if not claimed to count as one of the licensed professions
I know for sure that this is true at least in New York where my mother is a (licensed PhD-holding) psychologist, and in Quebec where I live now, but I think this is typical.
"Psychologist" and "psychiatrist" are of course regulated, as is "social worker," but the generic unregulated therapy terms lead to lots of underqualified people doing bad diagnosis and treatment.
