How you get your ticket: 5 steps +

Hold your 4th Class certificate. Every province requires it, except Quebec's separate system.
Build qualifying time in the role and plant size your regulator lists.
Take a 3rd Class course, which can cut 6 months or more off your steam time in most provinces.
Pass all four papers: 3A1, 3A2, 3B1 and 3B2.
Apply for your certificate with your operating experience form.

Eligibility requirements

Every province requires a 4th Class certificate first, then a set amount of experience in a specific role and plant size. Open your province for the details.

3rd Class power engineer FAQ

How many exams are in 3rd Class?

Four papers: 3A1, 3A2, 3B1 and 3B2. Under the SOPEEC standard each has 100 multiple-choice questions, 3 hours and a 65% pass mark. Ontario's TSSA exams have 150 questions in 3½ hours.

Do I need 4th Class before 3rd Class?

Yes. Every province that uses SOPEEC classes requires a 4th Class certificate first. Quebec has its own system, where class 3 follows class 4.

How much steam time do I need for 3rd Class?

Usually 12 months in the right role, such as chief engineer of a 4th Class plant or shift engineer of a 3rd Class plant (BC, Manitoba, Saskatchewan). Ontario requires 1,920 hours, or 160 after an approved full-time program. Approved courses cut 6 months or more in most provinces.

Can I study 3rd Class online?

Yes. BCIT, SAIT, NAIT, Lakeland, Northern Lakes, Keyano and NSCC offer online or distance options. Check that your regulator accepts the course and how much experience credit it gives.

What can a 3rd Class power engineer operate?

It depends on the province. In Manitoba, chief engineer of a high-pressure plant up to 5,000 kW; in Saskatchewan, chief engineer of high-pressure steam up to 5,000 kW and shift engineer up to 10,000 kW; in BC, chief engineer of a 3rd Class plant (100 to 500 m² of boiler capacity).

Is BoilerIQ official?
