Private investigators are commonly confused with private detectives. In the province of Ontario, private investigators are legally not allowed to represent themselves as private detectives. If you see a company representing itself as a Hamilton detective agency or private detective firm in Hamilton, ensure this title is accurate before agreeing to work with them.
