Short answer: private investigation in Ontario is a licensed trade under the Private Security and Investigative Services Act, 2005, and the individual licence has a defined path: meet the eligibility rules, complete the mandatory basic training with a registered provider, pass the ministry test, and apply online with your training completion number, a criminal record and judicial matters check, identification and a photo, plus the $80 fee. A correctly completed online application can take up to 15 calendar days to process, and the licence expires two birthdays after issue, renewable from 90 days out. That is the paperwork. What the paperwork does not teach is the job, and the honest half of this article is about that.
The licence, step by step
The sequence runs: confirm eligibility, train, test, apply. Training must be through a registered provider, and it ends in an Ontario training completion number you will need for the application. The test is the ministry’s, booked separately after training. The application itself is through ServiceOntario, and the supporting documents are specific: the completion number, a criminal record and judicial matters check in its official format, that is the middle of the three police-check types we explain in our background checks guide, two pieces of valid government identification, and a compliant photo. Employers cannot put you in the field as an investigator without the licence, so the sequence has no shortcuts worth taking; a lapsed or absent licence is not a technicality, it is an offence under the Act.
Eligibility, honestly read
Three requirements: at least 18 years old, legally entitled to work in Canada, and a clean criminal record as the licensing regulation defines it, which means not having been convicted of the offences listed in the eligibility regulation, or holding a record suspension for them. Note what is absent: no degree, no policing background, no minimum experience. The trade is genuinely open, which is one of its virtues, and the flip side is that the licence alone signals almost nothing to an employer, a point worth internalizing before you laminate it.
Training and the test
The mandatory basic training covers the legal framework, the PSISA itself and its Code of Conduct, the criminal and civil law the work brushes against, evidence handling, report writing and the mechanics of surveillance, and the ministry test checks that it stuck. Treat the syllabus as a floor, not the trade. The statutes you will actually work under reward a deeper read than any course provides, and the working versions of these topics are what our practitioner shelf exists for: the surveillance series on how the work is really done, the field kit, and the legal lines every file lives inside. One more honest note: Ontario is reviewing the PSISA, with consultation closed and outcomes pending, so the regime described here is current but not guaranteed static; we track that in our PSISA review explainer.
What agencies actually hire for
Here is the perspective from the hiring side of the desk. The licence is an entry requirement, not a differentiator, and prior policing or military experience, while common in the trade, is neither required nor automatically sufficient. What a serious agency is screening for is harder to fake: writing, because the report is the product and a brilliant surveillance day dies in a bad paragraph; patience and unremarkability, because surveillance selects for people who can be uninteresting for nine hours and alert in the ninth; judgment about legal lines under pressure, because one improvised trespass costs more than the file earned; and a background that does not compromise covert work. Our own roster draws from intelligence, military and law enforcement backgrounds, and also from people who read as anything but investigators, and that second group is not a compromise, it is often the point. If that mix describes you, our careers page is the door.
The craft, and the rules that keep you licensed
The fastest way to lose a new licence is to believe it grants powers. It does not: an investigator has no more legal authority than any citizen, no access to police databases, no exemption from trespass, interception or privacy law, and the Code of Conduct under the Act is enforced against exactly the corner-cutting that impresses no one. The investigators who last build the opposite reputation: files gathered from lawful vantage points, reports that survive cross-examination, and a licence number they are content to have checked, the way we invite clients to check ours in our verification guide. Learn the trade that way from the first file and the career takes care of itself.
Not legal advice

Requirements, fees and processing details are the ministry’s to change; confirm current specifics on the official licensing page before applying, especially while the PSISA review remains open.
Frequently asked questions
What are the requirements to become a private investigator in Ontario?
Be at least 18, be legally entitled to work in Canada, and have a clean criminal record as defined by the eligibility regulation (or a record suspension). Then complete the mandatory basic training with a registered provider, pass the ministry test, and apply online with your training completion number, a criminal record and judicial matters check, two pieces of government ID, a compliant photo and the $80 fee.
Do I need a police background or a degree to be a PI?
No. The licence has no education or experience prerequisite beyond the mandatory training and test. Agencies hire for writing ability, patience, judgment about legal limits, and a background compatible with covert work; policing and military experience is common and valued but neither required nor automatically enough, and people who do not read as investigators are often exactly what covert work needs.
How much does an Ontario private investigator licence cost?
The licence application fee is $80, with training costs on top of that, set by the registered training provider you choose. A correctly completed online application can take up to 15 calendar days to process, and the licence expires two birthdays after it is issued, renewable up to 90 days before expiry.
Can I work as a private investigator anywhere in Canada with an Ontario licence?
No. Licensing is provincial, and an Ontario licence covers work in Ontario. Other provinces run their own regimes with their own training and eligibility rules, so cross-border files are handled through investigators licensed where the work happens, which is standard practice for agencies with national reach.
