Eighteen trades, built to the standard
Pick your sheet.
Each trade is built against its official occupational standard and exam blueprint — question count, time limit, and the mix of recall, procedure and judgement. Free sample questions on every one. 4th Class Power Engineering (4A and 4B), the Ontario Gas Technician 3 (G3), the Ontario 313D Residential Air Conditioning Systems Mechanic exam and the Ontario and Alberta Master Electrician exams and the Ontario Building Code (BCIN) House, Small Buildings and Legal/Process exams have their own sections below.

Power Engineering · not a Red Seal exam
The 4th Class Power Engineer certificate is two papers, each passed on its own at 65 %. Paper A (4A) covers the theory, codes, safety and the boiler itself: mechanics, thermodynamics, codes and legislation, safety, electricity, instrumentation, and boilers and their systems; paper B (4B) covers operating the plant: lubrication, pumps and compressors, boiler safety devices, plant operation and maintenance, water treatment, turbines and engines, refrigeration and HVAC. Both papers are written to the SOPEEC syllabus that the member provinces and territories share, and each runs the exam through its own regulator: ABSA in Alberta, Technical Safety BC, TSASK in Saskatchewan, TSSA in Ontario and others. Writing both papers? All-Access covers 4A and 4B for $119.
Twelve units and 55 objectives on the SOPEEC syllabus, from elementary mechanics and steam tables to boilers and boiler systems, with calculations in the mechanics, thermodynamics, electricity and combustion units. None of SOPEEC, ABSA, Technical Safety BC, TSASK or TSSA publishes how many questions come from each unit, so the bank covers every objective. The Handbook of Formulae and Physical Constants and the steam tables are normally provided at the sitting.

The Gas Technician 3 (G3) is Ontario's entry gas certificate, issued by TSSA. A G3 works under the general supervision of a G1, G2 or DA holder.

Nine modules, from safety, tools and the properties of propane and natural gas to codes, acts and regulations, electricity, drawings, customer relations, piping and tubing and gas appliances. TSSA does not publish the G3 question count or how many questions come from each module (its prep guide says only that typical TSSA exams run from 50 to 165 questions depending on the certificate, with up to 3.5 hours), so the bank covers all nine modules and our timed practice exam is our own length: 100 questions in 180 minutes.

Six weighted skill sets on STO's counselling sheet: plan and prepare 7 %, assemble and install 21 %, commission 10 %, service 21 %, maintain 21 % and the electrical components 20 %. The sheet dates from 2016, and STO publishes no 313D question count (its exams run between 90 and 150 questions), so our timed practice exam is our own length: 130 questions in four hours, drawn by those weights.

Master Electrician (ESA, SCC) · not Red Seal exams
The Master Electrician (ME) licence is Ontario's licence for the master electrician an electrical contractor designates, issued by ESA, the Electrical Safety Authority. ESA's exam is 80 multiple-choice questions in three hours, open book with the latest OESC and ESA's Relevant Legislation book, written in person, and needs 70 % overall and at least 60 % in each of its three sections. In Alberta, the Safety Codes Council certifies master electricians after a 120-question exam in two parts, Alberta Acts and Regulations and the Canadian Electrical Code, written online and open book, which needs 60 % on each part and a 75 % average of the two.
Three sections of a third each: the Ontario Electrical Safety Code, Worker Safety and Business Administration. ESA does not publish how many questions each section has, so our timed practice exam draws 27, 27 and 26, and it scores both of ESA's rules: 70 % overall and 60 % in every section. Every question is original, written from the OESC rule numbers and the Ontario statutes.
