A private investigator is tasked with verifying an individual's residential address. They consider calling utility companies (hydro, gas) and impersonating the individual to obtain the information. Is this an acceptable information-gathering technique in Ontario?

1. Yes, but only if conducted by a licensed investigator
2. Yes, provided the information is not shared with third parties
3. No, impersonation is illegal and unethical, violating privacy legislation and potentially leading to criminal charges.
4. Yes, if the investigator believes it is crucial for their investigation
