When people search for confined space certification they usually mean the course certificate a trainer hands out. No government issues a confined space licence or certificate. What the law requires is that your employer makes sure you are adequately trained for the confined spaces you will enter or support, both in general hazard recognition and in the specific plan for each space, and keeps a record of that training.
This guide follows Ontario's Confined Spaces Regulation and the ministry's guideline for working in confined spaces, with B.C.'s WorkSafeBC rules where they add something. It covers who needs training, what it must include, attendants and rescuers, online courses, records and reviews. Every fact links to the official page it comes from. Always follow your own province's rules and your employer's written plan. To prepare for the written test at the end of your course, use the practice questions and mock exam linked below.
Step by step
Know that there is no government certificate
Ontario's ministry says there is no certification process for confined space trainers, workers, training programs or agencies. The employer, in consultation with the joint health and safety committee or health and safety representative, decides the level and type of training and must make sure it is adequate for the type of entry.

Every worker who enters a confined space or performs related work must get adequate training in safe work practices, including recognizing confined space hazards. The employer appoints a trainer with adequate knowledge, training and experience, and develops the training with the joint committee or representative. This general part can be bought from or contracted out to a training provider.

You must also be trained in the written plan for each confined space and follow it. Plan training can cover the hazards of that space, how they are evaluated and controlled, ventilation equipment, harnesses and air monitors, your personal protective equipment, entry procedures, what to do in an emergency and the work itself.

The ministry says instructions alone do not make a worker competent: all confined space training should include hands-on practice with the safety equipment, including personal protective equipment and harnesses. A new worker without enough experience can be teamed up with more experienced workers.

People who support the work from outside, such as attendants and rescue workers, need training too. Enough on-site rescue workers must be trained in first aid and CPR, the plan's on-site rescue procedures and the rescue equipment the plan requires, and calling 911 does not count as an on-site rescue procedure.
Source: Ontario — Guideline for working in confined spaces: On-site rescue procedures and equipmentMake sure your training is recorded
The employer must keep up-to-date written records of who gave and who received the training, the nature of the general training and the date. The records can be built into the entry permit. On construction projects, the employer must give the training records to the project's joint committee or representative on request.
Source: Ontario — Guideline for working in confined spaces: Training (O. Reg. 632/05, ss. 8, 9 and 9.1)Work only under a current entry permit
Before anyone enters, the employer must issue a separate entry permit each time work is to be done in the space. It names the attendant, records each worker's entries and exits and lists the entry and rescue equipment, and a competent person must check it against the plan before each shift.

Where to take the test
Through your employer. The general hazard recognition part can be bought or contracted out, including web-based training, but it may need to be supplemented with plan-specific training for your workplace, and the employer remains responsible for making sure the training is adequate.

What to bring or have ready
- To training: be ready for hands-on practice with the safety equipment, including personal protective equipment and safety harnesses, which the ministry says all confined space training should include. Source: Ontario — Guideline for working in confined spaces: Training
- At the job: know where the entry permit is. It need not be posted at the entrance, but it must be readily available to everyone who enters or performs related work while it applies. Source: Ontario — Guideline for working in confined spaces: Entry permit
- For a rescue role: training in first aid and CPR, the plan's on-site rescue procedures and the required rescue equipment, held by the rescue team as a whole. Source: Ontario — Guideline for working in confined spaces: On-site rescue procedures and equipment
After you pass
A course certificate covers only the general part. Before you enter, your employer must also train you in the plan for that specific space, record the training, and issue an entry permit for the work. Source: Ontario — Guideline for working in confined spaces: Training
Validity and renewal
Ontario's regulation does not set a fixed refresher interval. Outside construction projects, the employer must review the training at least once a year and whenever circumstances change, such as a new process or hazard assessment, and provide more training if the review finds it is not adequate. A review is not the same as annual training. Source: Ontario — Guideline for working in confined spaces: Training
Common mistakes
- Paying for a certified course on the belief that it is a government licence. No government certification process exists for trainers, workers or programs. Source: Ontario — Guideline for working in confined spaces: Training
- Treating an online course as complete training. Web-based training can be part of it, but it may need to be supplemented by plan-specific training, and all training should include hands-on practice with the equipment. Source: Ontario — Guideline for working in confined spaces: Training
- Relying on 911 as the rescue plan. Emergency services do not replace on-site rescue procedures that are ready for immediate implementation. Source: Ontario — Guideline for working in confined spaces: On-site rescue procedures and equipment
- Letting the attendant go in to help. The attendant must stay outside near the entrance during a rescue and can join the rescue team only if replaced by another person who knows the attendant's duties. Source: Ontario — Guideline for working in confined spaces: On-site rescue procedures and equipment
- Assuming contracted-out training moves the duty to the trainer. If training is contracted out, the employer still has to make sure it is adequate. Source: Ontario — Guideline for working in confined spaces: Training

FAQ
How to get confined space certification: common questions
Is there an official confined space certification in Canada?
Not from government. Ontario's ministry says there is no certification process for confined space trainers, workers, programs or agencies. The certificate from a course shows you completed that trainer's course; the legal duty is your employer's, to make sure you are adequately trained.
How much does confined space certification cost?
No government fee applies, because there is no government certificate. Course prices are set by trainers and training companies, and the regulation puts the duty to provide adequate training on the employer.
Can I get confined space training online?
Partly. Web-based training can be part of your training, but it may need to be supplemented with plan-specific training, and the ministry says all confined space training should include hands-on practice with the safety equipment.
How often does confined space training need to be renewed?
Ontario does not set a fixed refresher interval. Outside construction projects, training must be reviewed at least once a year and whenever circumstances change, and more training given if the review finds it inadequate.
Who can teach a confined space course?
In Ontario, the employer appoints a person with adequate knowledge, training and experience to conduct the training. Trainers and training organizations do not need to be certified.
How often must B.C. confined space rescuers practise?
WorkSafeBC requires a rescue practice drill at least once a year, and the employer of the rescue persons must keep records of their training and drills.
