Last verified August 19, 2026 against the sources listed below.

What can a PCI holder legally do in Ontario?

A PCI holder, or the holder of an equivalent record of training, may:

• Examine and requalify propane cylinders, following the procedures in the federal Transportation of Dangerous Goods Regulations (O. Reg. 215/01, s. 37 (2))

The full scope wording is in O. Reg. 215/01, s. 37, which prevails over any summary.

Is a certificate legally required for liquid propane work?

This certificate is required to perform work regulated under O. Reg. 211/01 (Propane Storage and Handling); O. Reg. 215/01, s. 2 (1) lists it among the certificates that must be held to do that work.

How do you get the PCI in Ontario?

Prerequisite

None beyond approved training. This class can be held as a TSSA certificate or as an equivalent record of training (O. Reg. 215/01, s. 37).

The training route

1. Complete an approved program at an accredited training provider. Certification requires a TSSA-approved curriculum delivered by an accredited provider (O. Reg. 215/01, s. 5 (1)).
2. Apply for the TSSA certification exam. Your provider submits proof of training; you book through the TSSA Client Portal. The practical assessment stays valid for 12 months after the program.
3. Pass the TSSA certification exam. Each attempt, including rewrites, is billed as a separate exam. Failing three times means completing a full accredited program before another attempt (O. Reg. 215/01, s. 5 (4)).
4. Pay the certificate fee. $136 for the initial certificate (from May 1, 2026, plus HST), per the TSSA Propane Fee Schedule.

The challenge route

Experienced workers can challenge the exam without formal training if TSSA is satisfied they hold equivalent knowledge and competence (O. Reg. 215/01, s. 5 (5)). The challenge examination costs $255.50, requires documented proof of work experience where the certificate has prerequisites, and still ends in a practical skills assessment.

Certificate or record of training?

The regulation allows this work to be done either by a TSSA certificate holder or by the holder of a record of training issued by an accredited training provider approved by the director (O. Reg. 215/01, s. 37). A record of training is not the same as the certificate: under s. 54, a record of training holder must undergo full retraining or skills retesting every three years, or sooner if the director requires it.

How often does the PCI need to be renewed?

Every two years. TSSA's fee schedules list the certificate fee as biennial, and the renewal costs $136 (from May 1, 2026, plus HST) with a $50 late payment fee after the renewal date.

Working on an expired certificate is prohibited outright: O. Reg. 215/01, s. 4 (1) says a person who fails to renew shall not do any work under the certificate after expiry. You can still renew up to one year after expiry, completing any upgrading course the director specifies. After one year, the certificate is gone and you start over as a new applicant (s. 4 (5)).

Where the PCI sits in the ladder

Filling cylinders is a separate authorization under the PPO classes.
