Security can support a workplace-violence program, but Ontario’s OHSA duties remain with the workplace parties identified by law. Hiring security does not transfer those legal responsibilities.
At a glance
- Ontario requires employers to prepare and review a workplace-violence policy at least annually.
- Security personnel may be part of prevention, access, response and reporting procedures.
- The organization still needs its own workplace-violence assessment, policy and program as required by law.
What this means in practice
The official rules establish a baseline, but a workable security assignment still needs property-specific decisions. The client and provider should turn general requirements into clear instructions about what is checked, who can authorize exceptions, what must be documented and when another authority takes over.
Questions to confirm
- What workplace-violence risks has the employer assessed?
- What is security expected to do when a concern is reported?
- How are workers informed about the program?
Picture this at your property
A retailer hires security after several aggressive-customer incidents. Security can support response and documentation, but the employer still needs to address its own OHSA violence obligations.
The value of the example is the decision process: identify what is known, what remains uncertain, who has authority, and what information should be preserved for follow-up.
Practical takeaway
The strongest security process is usually the one that makes responsibilities, observations and escalation clear. That creates a service that can be understood and reviewed without overstating what security can guarantee.
