How to Become a Private Investigator in Ontario

To Become a Private Investigator in Ontario is similar to most other places: you need to meet basic Private Investigator requirements such as age, language proficiency, and other usual requirements of this nature. Furthermore, to become a Private Investigator in Ontario, you need to take a government approved Ontario Private Investigator's license course.


Service Ontario Private Investigator Licensing

In Ontario, the government body that controls licensed Ontario Private Investigators is Service Ontario which is a government body acting under the Ministry of the Solicitor General.

So, it is Service Ontario that will approve Ont PI licensing courses:

After completing the PI course, you will need to pass a Service Ontario PI license test:

  • This is called the Basic Ministry Test.

  • Information on the test will be provided to you after completing the ON licensing course.

Once you submit the proof of your ability to meet the requirements and completion of the licensing course/ test to Service Ontario, you will get your Ontario PI license. Most jurisdiction will have a PI beginner’s license, Ontario does not. You will get to start out with a full Ontario Private Investigator license. This is where you need to start learning the practical PI skills you will be using.

Ontario Private Investigator Beginner License

The process of how to become a PI in many places starts with a beginner's license. Your Private Investigator beginner’s license in Ontario is just a regular Private Investigator license. It will allow you to work for a PI agency, but you will not be able to work for yourself (your own PI company).

This PI license means you must work under the supervision of a fully licensed Ontario PI agency. However, the term “under supervision” will be in namesake only. You will not be supervised or guided by an experienced Private Investigator. In fact, Ontario PI agencies are not economically structured to have mentor/ student surveillance teams. Furthermore, the Ontario licensing course will be great for learning PI legislation, but it alone will not set you up to become a successful Private Investigator. New Private Investigators still need to know how to be successful working operations. This is why practical Private Investigator education and training specifically for Private Investigators is necessary.

This lack of guidance is why so many new Ontario Private Investigators burn out and quit and why many experienced Private Investigators are jaded. On top of this, PI clients with small budgets typically get the new unqualified Private Investigators, nobody wins in this situation. It is also not fair to small PI clients to use their files to haphazardly train new Private Investigators.

So, the time comes for you to be a Private Investigator and work investigations with no Private Investigator experience or education. The Ontario licensing course you took focused on legislation, but you need practical Private Investigator training as well. You will always be told by employers that “soon you will get some PI training,” which never happens. It took me over five years to figure out the industry and get good at a few specialized fields. During that time, I struggled and probably lost several hundred thousand dollars due to losing work opportunities from a lack of skill and education. What is sad is that this is a common story in the industry. If you make it through this meat grinder and get an Ontario Private Investigator business license, you will be qualified to work for yourself with your own PI agency. Hopefully, when you are hiring new Private Investigators, you will appreciate the importance of proper PI education.
