1. People Looking for Missing Persons
Families hire private investigators to locate missing family members, runaway teens, or missing loved ones. Private investigators find missing individuals using legal databases, surveillance, and interviewing.

Private investigators help individuals get answers legally. For personal or business reasons, hiring a licensed private investigator makes sure that the investigation is done properly.
What Can a Private Investigator Do?
Private investigators in Canada are regulated closely, but they can do a lot of things legally. Here are some things they can do:
Surveillance
Private investigators in Ontario can follow and monitor individuals in public. They can follow someone in a car, take pictures of someone in public, or track movements. They can’t, however, enter private property without consent or secretly record private conversations.
Background Checks
One of the most common jobs of a private investigator is to obtain legal information about an individual. This can include checking former employment, criminal records (if permitted), or financial histories. Companies and individuals often hire private investigators for this purpose before making key decisions.
Finding Missing Persons
The best private investigators in Toronto handle missing persons cases. They can be a runaway, a long-lost relative, or someone trying to avoid legal trouble. Private investigators use legal methods to track people down. They search public databases, interview people, and scan online behavior for hints.
Gathering Evidence
Private investigators get hired by lawyers to get evidence for court cases. Taking pictures, speaking with witnesses, or proving statements in civil cases like adultery or fraud. All the evidence must be collected legally.
Verifying Records
Private investigators can obtain certain public and restricted records if they have legal authority. This can include property records, business registrations, or financial activity. They cannot, however, hack government databases or obtain confidential information without consent. Private investigators have valuable skills, but they must follow the law.

What Private Investigators Cannot Do
Private investigators have a number of ways to gather information, but they also face strict limits. Many people think they can do anything to solve a case, but that’s not true. Some things they cannot do in Canada are as follows:
Wiretapping
Private talks cannot be secretly recorded without consent; private investigators cannot use hidden microphones in private rooms or secretly record telephone calls, but they are allowed to listen and take notes in public.
Trespassing
Private investigators have to follow the same property laws as everybody else. They cannot break into houses, offices, or private rooms to gather evidence. Even if they believe someone is concealing information, they cannot enter restricted areas without consent.
Pretending to Be Law Enforcement
Some individuals think private investigators have the same authority as police, but that is not the case. A private investigator cannot claim to be an officer, show a fake badge, or force someone to answer. They can only gather facts legally without deceiving people.
Hacking
Accessing private emails, text messages, or phone records without permission is illegal. Private investigators cannot hack into social media accounts, bank records, or personal devices. They may use public records and legal methods to gather information, but anything beyond that is a crime.
Arresting Individuals
Even the best private investigators in Toronto do not have the right to arrest anyone. Even with concrete evidence against an individual, they are not allowed to arrest or hold people. They are to get information and submit it to their clients or police when needed.
A private investigator is trained to get information within legal boundaries. They have to follow privacy laws and cannot break rules even if a case is urgent. If you ever need to hire one, make sure that they follow the law and have a private investigator license to work legally in Canada.
Does Canada Require a License for Private Investigators?
Yes, you need a license to work as a private investigator in Canada. Each province has its own rules. However, in order to obtain a license, a private investigator must finish training and pass an exam.
Private Investigator License Rules
All of the requirements listed below must be met in order to work as a private investigator.
- Must be 18 years old.
- Your criminal record must be clean.
- You need to complete the government-approved training.
- Pass a licensing exam
- After that, you can work for a licensed agency or you can operate solely with a valid license.
Why Hiring a Licensed PI Matters
It is a private investigator’s responsibility to know what he can and cannot do. He follows legal methods, keeps a watch on privacy laws, and gathers information that may help them in court. Hiring an unlicensed investigator is risky because they might use illegal methods, which can put a client at the same risk of legal consequences as the investigator.
If you are willing to hire a PI, always verify their credentials so that you are hiring someone who is legally allowed to operate.
Final Thoughts
Are private investigators legal? The answer to this is yes, but they must follow strict rules. They have the ability to track people, check background records and gather evidence, but they cannot hack, trespass, or pretend to be law enforcement.
A private investigator can help with any task, including fraud, finding a missing person, or background checks, but only if they follow the law. Information from a licensed investigator will be accurate and legal.
