Ontario takes workplace safety seriously — and the numbers prove it. The Ministry of Labour, Immigration, Training and Skills Development (MLITSD) actively investigates incidents, conducts inspections, and prosecutes violations under the Occupational Health and Safety Act (OHSA). When companies cut corners on safety, the consequences are severe: criminal charges, six-figure fines, and — worst of all — workers who never come home.
Falls from heights are a leading cause of work injuries and deaths on Ontario construction projects.
The cases below are real. They involve real companies, real fines, and real workers who were seriously injured or killed because proper safety measures weren't in place. Every one of these tragedies was preventable.
In October 2018, a Windsor-area construction company was fined $150,000 after a worker was fatally injured in a fall from height. The investigation revealed that the company had failed to provide adequate fall protection for workers operating at elevation. There was no guardrail system, no travel restraint, and no personal fall arrest system in place at the time of the incident.
MLITSD-approved Working at Heights training teaches workers to identify fall hazards before they begin work. A trained workforce would have recognized the unguarded skylights and refused unsafe work — as is their legal right under the OHSA. Trained supervisors would have ensured fall protection systems were in place and inspected before anyone stepped onto the work surface.
In October 2017, a Windsor roofing company was fined $90,000 after a young worker fell from the roof of a house being re-shingled. The worker was in hospital for more than six months without regaining consciousness, and died. The ministry found that every worker on the roof had been supplied with fall protection and trained and tested in its use, but while carrying old shingles across the roof to the dumpster, the young worker apparently did not reattach their lanyard to the safety line.
This case shows how thin the margin is. The equipment was on site and the training had been done, but fall protection only works if it stays connected every time a worker moves. The legal duty to make sure workers are protected stays with the employer, even when the worker has been trained.
Equipment and training only protect workers if they are used every minute of the shift. Plan how workers will move between anchors and lines so they never have to unclip to get where they're going, and supervise it.
In July 2018, a restoration company was fined $125,000 after a worker was killed during brick repair work on a Toronto building. The worker was on the platform of a boom lift being raised to 50 to 60 feet when the machine tipped over, throwing the worker onto a concrete driveway.
This case serves as a stark reminder that safety devices only protect workers when they are left working. In fact, complacency among experienced workers is a well-documented risk factor. Workers who have "done it a thousand times" may skip steps, take shortcuts, or underestimate hazards they've encountered before without incident.
Working at Heights training isn't just for new workers. It reinforces critical habits, updates workers on current regulations, and — most importantly — keeps safety top of mind for those who might otherwise grow complacent.
In April 2018, a Mississauga construction company was fined $90,000 after a worker fell from a stepladder and suffered critical injuries. The worker was standing near the top of a 10-foot stepladder, reaching above a drop ceiling to connect electrical wiring. As constructor, the company had not provided a scaffold or other work platform for work that could not be done safely from the ground.
A $90,000 fine is significant. But the true cost of this incident goes far beyond the penalty paid to the court:
The financial penalty is the smallest part of the cost. The real price is paid in broken bodies, shattered families, and careers that end on a stretcher.
When you add up WSIB premium increases, legal defence costs, project delays, difficulty hiring, and the lasting damage to a company's reputation, the total cost of a serious fall incident can be many times the court-imposed fine.
In March 2019, a Tecumseh electrical contractor was fined $70,000 after a worker installing light fixtures at a Windsor industrial facility stepped off an elevating work platform into the ceiling space and fell about 6.5 metres through the suspended ceiling, suffering critical injuries. The worker was alone, unsupervised and not using fall protection, and the ministry found the worker had never been trained in fall protection, working at heights or elevating work platforms.
This is the case that should concern every employer in Ontario's construction industry. The worker who fell had never been trained to work at heights, and the company was convicted of failing to provide information, instruction and supervision as well as fall protection. The absence of training is itself a violation, and the MLITSD can and does issue orders and lay charges based on inspection findings.
Since April 1, 2015, all workers on construction projects who may use specific methods of fall protection must complete an MLITSD-approved Working at Heights training program. This is not optional. It is not a suggestion. It is the law.
Every case above was decided under older, lower limits. Ontario has since raised the maximum OHSA penalties to the highest of any province:
Courts must also now weigh aggravating factors written into the OHSA, including whether the offence caused death or serious injury, was committed recklessly, ignored an inspector’s order, or followed earlier convictions. And the ministry now has two years, not one, to lay charges.
Enforcement has not slowed either. In its 2024–25 campaign on falls in residential construction, the ministry made 6,978 field visits to 4,974 workplaces and issued 23,421 orders and requirements, including 2,448 stop-work orders. The most-cited problems were workers not using required fall protection and missing or inadequate guardrails.
Across all five cases, the same patterns appear again and again. These weren't freak accidents or unforeseeable events. They were predictable, preventable failures rooted in the same basic shortcomings:
The pattern is clear: when training is missing, when equipment is absent, and when supervision fails, workers get hurt or killed. Every single time, the outcome was preventable.
Compliance with Ontario's Working at Heights requirements is not complicated. It takes commitment, consistency, and a genuine belief that every worker deserves to go home safe. Here is what every employer in the construction industry should be doing:
The cost of a Working at Heights training course is $150 plus tax per worker. The cost of non-compliance — measured in fines, injuries, and lives — is immeasurably higher. The choice should be obvious.
