# Working at heights training — the Ontario certificate, and what it is not

In Ontario, a mandatory training program a construction worker must complete, from a Chief Prevention Officer–approved provider, before using a fall-protection system. The certificate is valid for three years and is required on top of, not instead of, employer-specific training.

Ontario made this training mandatory for construction workers who use fall
protection. The program is set by the Chief Prevention Officer, delivered by
approved training providers, and recorded on a public register — which means an
employer can verify a worker's certificate rather than take a card at face value.

## What it means in practice

- **Three years, then a refresher.** The refresher is shorter than the initial
  program, and letting it lapse means starting over rather than topping up.
- **It does not travel with the worker into other duties.** The certificate covers
  the general principles; the employer still owes site-specific and
  equipment-specific training on the actual anchor points, the actual rescue plan
  and the actual equipment in use.
- **A rescue plan is part of the job, not part of the certificate.** Suspension
  trauma makes "we will call 911" an inadequate answer, and the plan is the
  employer's to write.

## What it is not

**It is not a national requirement.** This is Ontario construction. Other
provinces require fall-protection training and equipment, but through their own
regulations, their own thresholds — the height at which fall protection is
triggered is not the same everywhere — and without an equivalent
provincially-approved certificate. A worker moving from Ontario to Alberta does
not carry a transferable ticket.

**It is not equipment inspection.** The training tells a worker how to use a
system; whether the harness is still fit to use is a separate, recurring
obligation with its own record.

**And it is not the French VGP or the German _Prüffrist_.** Those govern the
equipment; this governs the person. Confusing them produces a register that
tracks certificates and never notices a harness that has expired.
