Achieve Safety is a Chief Prevention Officer (CPO)–approved provider of Working at Heights training in Ontario. Our program prepares construction workers and supervisors to safely assess and control fall hazards while meeting mandatory provincial safety requirements.
This training covers fall prevention and fall protection techniques, ladder safety, equipment inspection, and safe work practices required under Ontario’s Occupational Health and Safety Act (OHSA) and construction regulations. Successful completion results in Ministry-approved Working at Heights certification, recognized across Ontario construction projects.
Yes. Working at Heights training is mandatory in Ontario for workers on construction projects who may be exposed to fall hazards of 3 metres or more and who may be required to use fall protection systems. Under Ontario law, employers must ensure that affected workers complete CPO-approved Working at Heights training before performing elevated work. This requirement applies regardless of experience level, job title, or length of time on site.
Achieve Safety delivers a CPO-approved Working at Heights training course in Ontario that meets all requirements established by the Ministry of Labour, Immigration, Training and Skills Development under the Occupational Health and Safety Act (OHSA) and O. Reg. 297/13.
This is an 8-hour standardized training program designed specifically for construction work where fall hazards exist. The course follows the provincial Working at Heights Training Program Standard and includes both classroom instruction and hands-on practical evaluation, as required by law.
Only Chief Prevention Officer–approved providers are permitted to deliver this training and issue valid certification. Training that is not CPO-approved does not meet Ontario’s mandatory requirements and may not be accepted during inspections.
The Working at Heights training course prepares workers to safely perform construction tasks where there is a risk of falling. The focus is on hazard recognition, prevention, and correct use of fall protection systems, not just awareness.
By the end of this 8-hour course, participants will be able to:
Enroll today to gain skills in evidence gathering, root cause analysis, and OHSA-compliant reporting.
Working at Heights training requirements in Ontario are determined by hazard exposure, not job title.
Employers must ensure that any worker on a construction project who may be exposed to a fall hazard of 3 metres or more completes CPO-approved Working at Heights training before performing the work.
If fall protection is required to perform the task safely, training is required. Training is required for workers who may need to use fall protection systems while performing construction work, including:
Workers performing tasks on construction projects where there is a risk of falling from heights, including framing, roofing, formwork, or structural work.
Electricians, painters, window installers, and similar trades who regularly work from ladders, platforms, or elevated surfaces on construction sites.
Workers performing maintenance, repairs, or installations on construction sites where fall protection is required under construction regulations.
Supervisors responsible for overseeing work at height, monitoring fall protection use, and ensuring workers follow safe work procedures.
Working at Heights certification in Ontario is not permanent. Employers are responsible for ensuring that training remains valid, current, and properly documented.
After successful completion of a CPO-approved course, workers receive Working at Heights certification valid for three years.
The validity period:
Starts from the course completion date
Applies across Ontario construction projects
Must not expire while the worker is performing work at height
If a certificate expires, the worker is no longer considered trained and must not perform work at height until refresher training is completed.
Refresher training is required before the certificate expires.
Employers should not wait until expiry has passed. If a worker’s certification expires:
The worker must stop working at height
Refresher training must be completed before work resumes
Refresher training confirms that workers still understand:
Fall hazard recognition
Proper use of fall protection systems
Current regulatory expectations
Allowing a worker to continue working with expired certification is a common compliance failure during inspections.
Workers exposed to fall hazards on construction projects must hold valid, Ministry approved Working at Heights certification before performing elevated work.
Fall protection equipment must be selected, inspected, and used correctly in accordance with Ontario regulations and site specific work conditions.
Supervisors must plan work at height, monitor fall protection use, and ensure unsafe conditions are corrected immediately.
Online Working at Heights training in Ontario is often misunderstood.
While some parts of the training may be delivered online, not all online courses meet Ontario’s legal requirements.
Ontario requires that Working at Heights training:
Be CPO-approved
Follow the provincial Working at Heights Training Program Standard
Include both theory and practical evaluation
Verify that participants can correctly use fall protection equipment
Because of this, fully online or “free” Working at Heights courses do not meet Ontario’s mandatory requirements if they do not include a proper practical component and CPO approval.
Courses advertised as free online Working at Heights training are typically:
Awareness-based only
Not CPO-approved
Missing mandatory practical evaluation
These courses do not satisfy Ontario’s legal requirement for Working at Heights certification and should not be relied upon for construction work where fall hazards exist.
