The phrase appears throughout Canadian OHS regulation — a competent person inspects the scaffold, assesses the confined space, signs off the fall-protection plan. Wherever it appears, the definition converges on the same three elements: qualification through knowledge, training and experience; familiarity with the applicable legislation; and knowledge of the hazards actually present here.
What it means in practice
- It is assessed per task, not per person. Someone can be competent to inspect a harness and not competent to assess a confined space. A blanket designation is a designation you cannot defend.
- The third element is the one that fails. An external specialist may hold the qualification and know the law, and still not know this site’s hazards. That is usually solved by pairing them with someone who does, not by ignoring it.
- It has to be demonstrable. The record is the training certificate, the experience, and the evidence that the person was actually briefed on this workplace.
What it is not
It is not a certification. No Canadian jurisdiction issues a general “competent person” ticket. Where a specific certificate is required — working at heights in Ontario, for example — that is a separate, named requirement.
It is not a supervisor. Supervisor is a defined role with its own duties; a competent person may be a supervisor, a worker, or an outside contractor. The two are separate tests and satisfying one says nothing about the other.
And it is not the French personne compétente by another name. The French term appears in a narrower set of obligations, mainly around periodic verification, and carries none of the general-duty weight the Canadian phrase does.
