Ontario Private Security & Investigative Services Act (PSISA)
PSISA (administered by the Ministry of the Solicitor General) licenses security businesses and individuals in Ontario. Related to electrical and low-voltage work, the Electrical Safety Authority (ESA) licenses low-voltage contractors and mandates the safety standards that low-voltage installations must meet.
Applies to
Security integrators, guards, investigators, and agencies operating in Ontario.
What it requires
The obligations, in plain English.
Licensed agency
A business providing security services, monitoring, or installation in Ontario must hold a current licence.
Licensed individuals
Technicians and guards must hold individual licences appropriate to the work they perform.
Electrical safety (ESA / OESC)
Low-voltage cabling and installations must meet the Ontario Electrical Safety Code and are subject to ESA inspection.
Insurance and bonding
Licensed security businesses must carry prescribed minimum insurance coverage and bonding.
How we design against it
From rule to drawing.
Current licences on file
PSISA agency licence and ESA low-voltage contractor authorization maintained and produced on any client request.
Licensed technicians dispatched
Every technician on your site holds current PSISA credentials, verifiable through the provincial registry.
OESC-compliant installation
All low-voltage cabling follows the Ontario Electrical Safety Code — pathway, termination, and fire-stop conformity.
Documented chain of custody
Who installed what, when, and with which licence — recorded in our project files for 7 years.
Common mistakes
What gets flagged on audit.
Using a contractor licensed for line-voltage but not for low-voltage work.
Sub-contracting to unlicensed sub-trades.
No project-level record of licences used, which breaks down on audit.
