Class by class in Saskatchewan
Examination format below is from TSASK's examination pages. Operating authority is from The Boiler and Pressure Vessel Regulations, 2017 (B-5.1 Reg 2), section 122, not from the obsolete Reg 1 excerpt. Ordinary high-pressure chief limits, shift limits, low-pressure plants, oilfield once-through plants, and refrigeration are separate. Refrigeration quantities that are capped are in tonnes, not kilowatts. The kilowatts in the time section are qualifying plants, not this operating authority. Fees elsewhere on this page are unchanged.

5th Class
How you get in. TSASK's page is built as pass the exam and meet an experience route. Several routes also require an approved course. There is a full-time approved course route that includes operating experience.
Time in a plant. Examples on the page: 12 months in charge of a low-pressure plant of at least 300 kW while holding a fireman boiler operator certificate; 12 months assisting a high-pressure boiler of at least 30 kW; or 12 months assisting a low-pressure plant of at least 1,000 kW. Longer assisted-operation routes apply if you also finish an approved course. An approved course can credit 6 months toward the 12-month routes. The page lists further routes. Plant capacity is the total of the boilers installed.
What the ticket covers. Section 122(5): as chief, ordinary high-pressure up to 500 kW, low-pressure of any capacity, and oilfield once-through up to 500 kW. As shift, ordinary high-pressure up to 1,000 kW, low-pressure of any capacity, and oilfield once-through up to 2,000 kW. Refrigeration up to 200 tonnes. Do not collapse those into one kilowatt cap.
The exam. One paper. TSASK's examination page: 100 multiple-choice questions, 3 hours, 65%.

Time in a plant. Examples: with a 5th Class certificate, 12 months as chief of an oilfield once-through plant over 250 kW, or 12 months operating a high-pressure plant of at least 250 kW. Without a 5th, 12 months assisting a high-pressure plant of at least 1,000 kW. Low-pressure chief and assistant routes run 24 months at higher capacities. A graduate-engineer route and a process-operator route are also listed. An approved course can credit 6 months toward several of the operating routes.
What the ticket covers. Section 122(4): as chief, ordinary high-pressure up to 1,000 kW, low-pressure of any capacity, and oilfield once-through up to 5,000 kW.

Oilfield once-through plants use higher thresholds. An approved course can credit 6 months, and an approved 2-year program can credit 9 months, toward several routes. A graduate-engineer route is 6 months on a high-pressure plant over 1,000 kW.
What the ticket covers. Section 122(3): as chief, ordinary high-pressure up to 5,000 kW, low-pressure of any capacity, and oilfield once-through up to 10,000 kW.
