In Canada, poor ladder safety causes accidents more often than most employers realize. In fact, data from Height Works shows 22,710 ladder injuries in a single year. Also, ladder falls caused 161 deaths. Next, look at Ontario data. The Workplace Safety and Insurance Board (WSIB) recorded 242 ladder injury claims in 2024. That means roughly one injury happened every single working day. And, each hurt worker lost an average of 29 days on the job..
These are not just numbers on a page. Behind every statistic is a real worker who went to a job site expecting an ordinary day and came home permanently changed - or did not come home at all.
Every employer knows about ladder safety. However, too few workplaces take it seriously until a bad accident happens. So, this guide covers the most common ladder risks. Then, it breaks down provincial safety laws. Finally, it gives you easy steps to stop injuries on the job.

Why Ladder Safety Matters in Every Workplace
Ladders are used on almost every Canadian job site. For example, teams use them in construction, warehouses, and maintenance. However, using them every day makes people forget about ladder safety. Workers often climb without checking the equipment. Plus, they forget to check the angle or if they have the right tool for the job.
The Canadian Centre for Occupational Health and Safety (CCOHS) points to four main causes of ladder accidents. First, using the wrong ladder for the job. Second, climbing a damaged or worn out ladder. Third, setting it up wrong. Also, a lack of proper ladder safety training. Surprisingly, unsafe actions cause over 95% of these falls—not broken equipment. That means nearly every single ladder injury is completely preventable.
Falls from ladders and scaffolding cause terrible harm in a single year. For instance, Public Health Ontario data shows these falls lead to 20 deaths, 88,000 emergency room visits, and 1,024 hospital stays. Clearly, the human cost is massive. On top of that, employers face terrible consequences. Think about heavy fines, lost work time, and higher insurance costs.
The good news is that most ladder accidents follow a predictable pattern. Once you understand how and why they happen, you can take real steps to stop them.
Most Common Ladder Accidents and Their Causes
Knowing which accidents happen most often is the first step toward preventing them. The majority of ladder incidents fall into a few categories that repeat across industries and provinces.
Overreaching and losing balance is the most common cause of ladder falls. A worker climbs up, reaches a little too far to avoid having to come back down and move the ladder, and the shift in weight tips either the ladder or the worker. This happens most when people are rushing.
The wrong ladder angle causes more accidents than most people think. A ladder that is too steep can fall backward. One set at too shallow an angle can slide at the base. The 4-to-1 rule - move the base one foot out for every four feet of height - exists for a reason, but busy sites often ignore it.
Using a broken ladder is a huge risk under deadline pressure. In reality, cracked rails, bent rungs, or missing parts make it unsafe. To prevent this, the Canadian Standards Association (CSA) sets strict rules under standard Z11-18. Therefore, workers must check their equipment before climbing. Any tool that fails the test must leave the job site right away.
Climbing with tools in your hands is dangerous. Basically, it removes a point of contact from the ladder and ruins your balance. Because of this, workers often slip and fall. Instead of carrying items, you should always use a tool belt or a hoist. Doing this removes a risk that is completely avoidable
Using the wrong type or grade of ladder is a widespread problem. The CCOHS identifies three portable ladder grades: Grade 3 (light duty), Grade 2 (medium duty), and Grade 1 (heavy duty). Using a light-duty ladder on a heavy task - or using a conductive aluminum ladder near live electrical work - can lead to serious injury.
Choosing the right tool for the job is vital. So, consult the Types of Ladders and Their Uses guide before making any worksite decision.
Top Ladder Safety Rules Workers Should Never Ignore
Ladder safety rules are not suggestions. Across most Canadian provinces, occupational health and safety legislation backs them. Breaking them can lead to stop-work orders, fines, and serious legal liability if a worker gets hurt. Every worker who uses a ladder needs to know the following rules.
Keep three points of contact at all times. Two hands and one foot, or two feet and one hand must be on the ladder whenever climbing or coming down. Canada's Occupational Health and Safety Regulations state this directly.
Never stand on the top three rungs. The higher a worker climbs, the more unstable the ladder becomes. The top three rungs are off-limits - all tools and materials must be within comfortable reach before going up.
Inspect the ladder before every use. No ladder goes up without a quick visual check. Look at the rungs, rails, locking mechanisms, safety feet, and spreader bars.
Set the ladder at the correct angle. The 4-to-1 rule applies to all straight and extension ladders. An extension ladder reaching a roof must also extend at least three rungs above the landing point to give the worker a safe handhold.
Secure the ladder at the top and base. Tie the top to a fixed anchor whenever possible. Place a non-slip mat under the feet or have a second person hold the base.
Never use a ladder on ice, snow, or wet ground without securing the feet. Canadian worksites face winter hazards that many safety guides fail to address. The CSA Z11-18 standard includes cold-weather guidance for exactly this reason.
Do not carry materials by hand while climbing. Use a tool belt, pouch, or hoist. Keep both hands free for contact with the ladder.
Canadian Ladder Safety Regulations Every Employer Should Know
In Canada, ladder safety rules fall under federal and provincial laws. As you might expect, the rules change depending on your location. They also change based on your industry. Ultimately, employers must know the exact regulations for their specific workplace
Federal workplaces have specific rules. To start, they must follow the Canada Occupational Health and Safety Regulations (SOR/86-304). Under these rules, workers must keep a three-point contact on fixed ladders. Also, your fixed ladders must meet ANSI Standard A14.3-1984.
Provincial rules protect workers across Canada. For example, the Ministry of Labour in Ontario sets local safety rules. Meanwhile, WorkSafeBC covers British Columbia, and Alberta Occupational Health and Safety handles Alberta. To make things easy, the CCOHS keeps a searchable database. You can use it to track ladder laws across all Canadian regions.
All portable ladders used on Canadian job sites must meet CSA Standard Z11-18 (R2022). Employers should confirm that every portable ladder on their site carries a CSA mark before they allow anyone to use it.
Employers have clear duties across most provinces. First, you must regularly inspect every tool. Any broken equipment must leave the site immediately. Next, you must train workers in safe ladder use before they work at heights. Furthermore, you must provide proper fall protection when people work high up. Finally, you must write down all of these safety steps in your company program.
Rules can change depending on your job type or province. In fact, certain industries have extra safety duties. Because of this, employers must check their local regulations. To help you out, our Workplace Ladder Safety Compliance Guide offers a full summary of what compliance looks like across Canadian provinces.
Ladder Safety Tips to Prevent Falls and Serious Injuries
Regulations only set the lowest safety bar. In reality, a strong safety culture pushes your team much further. Clearly, daily habits are what separate safe workplaces from those with constant accidents. To protect your team, use these practical tips to build a better record today.
Plan before you climb. Before anyone goes up a ladder, run through a quick checklist. Is this the right type of ladder? Does it reach high enough? Is the ground level and firm? Could a safer option work instead? Two minutes of planning at the start can prevent weeks of recovery time.
Always pick the right ladder for the job. For instance, use step ladders for interior work. Use extension ladders for roof access. Finally, try platform ladders when you need both hands free. Choosing correctly matters.
Keep the area around the ladder clear. A cluttered base is a trip hazard for the worker coming down and for anyone passing by. Use cones or barriers in high-traffic areas to mark the ladder zone.
Never stretch - descend and reposition instead. If the work point is not comfortably within reach, come back down and move the ladder. Overreaching is one of the leading causes of falls.
Wear clean, dry footwear with good grip. Smooth-soled shoes, wet boots, or muddy footwear all increase the chance of slipping on a rung. Clean, dry soles with a tread are the basic standard.
Adjust for Canadian weather conditions. Wind, rain, ice, and direct sun all affect ladder stability and grip. In winter especially, outdoor ladder use requires rubber foot replacements, anti-slip pads, and a spotter at the base.
How Ladder Safety Training Reduces Workplace Accidents
Training is the best step to stop ladder accidents. In fact, the CCOHS names poor training as a main cause of falls. Unfortunately, many companies have a bad habit. They just point a new worker toward the ladder shed. Basically, they let them figure it out alone.
Good ladder safety training does more than cover basic rules. It explains the logic behind them. For instance, workers need to understand why three-point contact actually works. Learning how weight shifts on a ladder helps them stay safe. Consequently, they will use these habits every time—not just when a supervisor is watching.
Good training also helps people spot dangers early. Specifically, workers learn to see a broken ladder before it fails. They notice unstable ground before setting up their equipment. On top of that, they realize when a job is too big for a ladder to handle. In reality, these judgment skills stop the accidents that rules alone cannot catch.
Online training is a great choice for busy teams. Basically, workers can complete a course on their own schedule. Next, they earn a certificate to document their training. Ultimately, they return to work ready to use their new skills on their very next shift.

Warning Signs Your Ladder Is Unsafe to Use
A damaged ladder does not always look broken at first glance. Many ladder failures start as small defects that workers ignore until they cause a serious incident. Workers and supervisors need to know exactly what to look for.
Pull a ladder from service immediately if you notice any major damage. For example, check for cracks or splits in the rails. Next, look for bent rungs that can cause you to slip. Also, watch out for broken safety feet at the base. In fact, step or extension ladders are unsafe if the locks fail. On top of that, check for rust on metal or warped spots on wood. Finally, do not climb if the safety labels are missing. Clearly, you need those labels to know the weight limits
Tag out any ladder showing these signs, remove it from the work area, and have a qualified person repair or destroy it. Do not store it in a corner "just in case."
Best Practices for Safe Ladder Setup and Use
Setup errors are behind a large share of ladder accidents. A ladder in perfect condition and correctly selected can still hurt someone if a worker sets it up wrong. These practices cover the full setup process.
- Check the surface before you place the ladder. The ground must be firm, level, and able to support the combined weight of the ladder, the worker, and any tools or materials. Soft soil, gravel, and uneven pavement all need extra stabilization or a different approach entirely.
- Apply the 4-to-1 rule. For every four feet of working height, the base must be one foot away from the structure. A ladder reaching 16 feet should have its base four feet from the wall. Canadian job sites ignore this setup rule more than almost any other.
- Extend the ladder past the landing point. When using a ladder to reach a roof or elevated platform, extend it at least three rungs above the edge. This gives the worker a solid grip when stepping on and off.
- Secure both top and base. Tie the top to a fixed anchor point whenever the task allows. Place a non-slip mat under the feet or have a second person steady the base throughout the job.
- Always face the ladder when climbing and descending. Facing outward shifts your weight forward and away from the ladder, increasing the chance of tipping backward.
Common Ladder Safety Mistakes That Lead to Workplace Injuries
Even experienced workers pick up habits over time that slowly drift away from safe practice. These are the mistakes we see most often on Canadian worksites, and the ones most likely to lead to an injury.
Skipping The Inspection
Workers who use the same ladder every day often stop looking at it. A ladder can crack, lose a safety foot, or develop a loose mechanism between uses. Familiarity is not a substitute for checking.
Using A Ladder That Is Too Short
Workers often stretch from the top rungs instead of getting the right tool. Alternatively, they step onto the structure they are trying to reach. In reality, both moves create a massive fall risk. Because of this, Canadian inspectors cite these actions more than almost any other violation.
Setting The Ladder At The Wrong Angle
Many people set up quickly by eye instead of measuring. Consequently, they regularly get the angle wrong. The ladder ends up too steep or too shallow. Clearly, both situations are highly dangerous.
Working Alone At Height
You should always have a second person at the bottom. Basically, they can hold the base and watch for dangers. Plus, they can call for help if something goes wrong. Sadly, many falls become fatal simply because no one was there to respond.
Using Improvised Platforms
Never use boxes, chairs, or pallets instead of a real ladder. In fact, stacked materials cause a huge number of serious falls. Ultimately, if the right equipment is not on site, the task must wait.
How to Create a Safer Workplace with Better Ladder Safety Procedures
Ladder safety is not a one-time training event. In reality, it is an ongoing system of policies, habits, and inspections. The best workplaces treat safety as a living part of daily work. Clearly, it is not just something to check off during onboarding.
To start, building this system requires a written company policy. This document must cover tool choices, inspection steps, and setup standards. Also, it must list banned actions and penalties for breaking rules. Ultimately, every worker who climbs must know what is in that policy.
Next, supervisors must perform regular site audits and walkthroughs. Doing this reinforces the rules where it matters most on the job. When done right, workers see that shortcuts are not allowed, and the culture shifts. Unfortunately, if you never follow up, workers forget their training quickly.
Tracking your equipment is equally important. For example, employers should keep an inventory of all ladders. You must inspect them on a regular schedule. On top of that, you must tag and remove broken units immediately. Store them completely away from usable tools.
Finally, employers need to refresh training regularly. New hires need it from day one. Meanwhile, long-serving workers need updates to fix bad habits. Fortunately, a flexible online program makes ongoing training easy without disrupting your daily schedule.
Protect Your Workers Before the Next Ladder Accident Happens
Every year, ladder accidents hurt thousands of Canadian workers. Sadly, these injuries were entirely preventable. The massive costs to workers and employers do not have to happen.
Remember, a ladder accident does not give a warning. It happens in a split second when you feel comfortable. For instance, it happens when someone reaches a little too far or sets up too fast. In fact, people often climb a tool they have used dozens of times before, never realizing it is now unsafe.
Ultimately, the best protection is preparation. This means proper training, daily inspection habits, and correct setup steps. Clearly, your team must know what ladder safety looks like on a real job site—not just in a manual.

Frequently Asked Questions
What is the most common cause of ladder accidents?
Overreaching and losing balance top the list. Unsafe actions, not equipment failure, cause over 95% of portable ladder incidents.
What is the 4-to-1 rule?
For every four feet of ladder height, the base must sit one foot away from the wall or structure. This keeps the ladder at a safe, stable angle.
How often should a ladder get inspected?
Every time, before each use. Workers should also expect a more thorough inspection on a regular schedule set by their employer.
What ladder standard applies in Canada?
CSA Standard Z11-18 (R2022) sets the minimum requirements for portable ladders used on Canadian job sites.
Do employers need to provide ladder safety training?
Yes. Occupational health and safety legislation across Canadian provinces requires employers to train workers in safe ladder use before they work at heights.
Can I use an aluminum ladder near electrical work?
No. Aluminum conducts electricity, so workers should never use a conductive ladder near live electrical work. A fibreglass or wood ladder is the safer choice.
What should I do if a ladder looks damaged?
Pull it from service right away. Tag it, remove it from the work area, and have a qualified person repair or destroy it.
