Canada's Asbestos Brake Pad Dilemma

The hum of a well-maintained vehicle often masks a silent, insidious threat: asbestos. For decades, this fibrous mineral was a staple in automotive brake pads, valued for its exceptional heat resistance and friction properties. While Canadian manufacturers largely ceased using asbestos in the late 1980s, the legacy of this dangerous material continues to haunt former workers, and a new wave of concern has emerged with the ongoing import of asbestos-containing brake pads into the country. This article delves into Canada's complex relationship with asbestos in the automotive sector, exploring the devastating human cost, the current legislative landscape, and the crucial steps being taken to protect mechanics and consumers from this persistent hazard.

A Haunting Legacy: The Human Cost of Asbestos Brakes

For individuals like Rick Garant, the memories of working in old brake factories are stark and unsettling. He vividly recalls the asbestos-filled dust that swirled around the Tilbury, Ontario plant in the 1980s, where white masks would turn black by the end of a shift, and blowing one's nose would yield similarly dark results. This plant, like many others producing brake pads for commercial trucks, relied heavily on asbestos until the late 1980s. The long-term consequences of this exposure are now tragically clear.

More than 25 years after their exposure, an increasing number of former Ontario brake workers are falling ill. While Rick Garant, at 48, remains healthy, his time as president of the CAW local in Tilbury from the early 1990s to 2007 saw him file over a dozen workers’ compensation claims for sick employees. The toll was immense: "Lots of people died," he recounts, having dealt with cases of pleural plaques, asbestosis, mesothelioma, and lung cancer. Many workers were caught by surprise, initially dismissing their symptoms as a persistent stomach flu.

The grim reality is painfully evident at the local Tilbury CAW office, where headshots of deceased brake plant retirees are marked in yellow, a stark visual testament to the insidious nature of asbestos-related diseases. Kevin Smyth, 54, whose photograph adorns the wall, was the first from the plant to file an occupational disease claim. Diagnosed with lung cancer at 42, his life was irrevocably altered by painful surgeries and treatments for a tumour he described as resembling a 'meatball' in his windpipe. The Workplace Safety and Insurance Board (WSIB) attributed his cancer to asbestos exposure at the plant, a revelation that set a chilling precedent for his colleagues: "You find out what everyone else could face."

The problem extends beyond Tilbury. In St. Catharine’s, Ontario, ten former auto workers exposed to asbestos brakes at a General Motors factory between the 1960s and 1980s have filed similar claims, most of them for mesothelioma. Bruce Allen, Vice President of CAW Local 199 in Niagara, believes these are just the beginning, predicting hundreds more cases over time. The Association of Workers’ Compensation Boards of Canada reported approximately 340 asbestos-related deaths in 2005, accounting for 61 percent of all occupational disease deaths that year. Dr. Marc de Perrot of the University Health Network in Toronto confirms that mesothelioma cases in Canada are increasing exponentially and rapidly. The latency period for these diseases, spanning 10 to 40 or more years, means that the full extent of the tragedy is still unfolding.

The Persistent Threat: Imported Asbestos Brake Pads

Despite the awareness of asbestos hazards dating back to 1948, when General Motors’ chief industrial hygienist noted the dangers, many brake manufacturers continued using the fibres for decades. While Canadian brake pad manufacturers have ceased using asbestos, the problem has not disappeared. According to Statistics Canada, over $2.6 million worth of asbestos-containing brake pads entered Canada in 2011 alone, with more than half destined for Ontario. This ongoing influx of imported aftermarket brake pads poses a significant and renewed risk.

This alarming situation has prompted action. On Wednesday, March 21 (the original date of the article's source material), an Ontario Member of Provincial Parliament (MPP) tabled a bill. If passed, this legislation would ban the import of these millions of dollars worth of asbestos pads that continue to enter the country each year. Such a ban would be a crucial step in preventing further exposure and protecting current and future generations of workers and consumers.

Are Auto Brake Mechanics Still at Risk?

The short answer is unequivocally yes. The presence of asbestos in aftermarket replacement brake pads creates an increased risk of asbestos-related disease for auto brake mechanics. The primary sources of exposure occur during the removal of dust from brake drums and assemblies, and when brake linings are machined before installation. These operations release fine asbestos fibres into the air, which, if inhaled, can lead to severe and often fatal occupational diseases.

It's crucial to understand that asbestos is dangerous to work with in any form. For many years, it has been recognised as a health hazard for workers involved in asbestos mining, processing, and installation of asbestos products. Auto brake mechanics are known to be especially at risk of developing these debilitating diseases, which, as previously mentioned, include respiratory problems, mesothelioma, and lung cancer. All automotive and truck repair garages and brake repair shops are potential hazard locations.

Navigating the Regulations: Protecting Workers in Ontario

The Ministry of Labour, Training and Skills Development (MLTSD) in Ontario considers all potential worker exposures to asbestos a serious workplace hazard. While the MLTSD encourages the substitution of hazardous products with less hazardous alternatives, specific legislative and regulatory requirements are in place to manage existing risks.

Asbestos is a designated substance under Ontario's Occupational Health and Safety Act (OHSA). Three regulations under OHSA address occupational exposures to asbestos, with O. Reg. 278/05 (Regulation respecting Asbestos on Construction Projects and in Buildings and Repair Operations) being particularly relevant to vehicle repair operations, including brake repairs. Unless a repair shop owner definitively knows that brake pads do not contain asbestos, or has an examination carried out pursuant to section 10(2) of O. Reg. 278/05, the pads must be assumed to contain asbestos.

Classifying Brake Repair Operations: Type 1 vs. Type 2

For the purposes of O. Reg. 278/05, most brake repair operations are classified as either Type 1 or Type 2 operations, each with specific requirements:

Type 1 Operations (Lower Risk Examples):

• The installation and removal of brake pads where they are installed or removed without being broken, cut, drilled, abraded, ground, or sanded.
• The breaking, cutting, drilling, abrading, grinding, or sanding of brake pads where they are wetted to control the spread of dust or fibres, and the work is done only by means of non-powered hand-held tools.

Measures and procedures for Type 1 operations (set out in section 14 of O. Reg. 278/05) include:

• Removing any visible dust on the pad or drum with a damp cloth or a vacuum equipped with a HEPA filter before beginning work.
• Controlling the spread of asbestos dust using appropriate measures, such as an impervious drop sheet (e.g., polyethylene), which must not be reused and must be disposed of correctly.
• Never using compressed air to clean up or remove dust from any surface.
• Prohibiting eating, drinking, chewing, or smoking in the work area.
• Providing an air-purifying half mask respirator with an N-100, R-100, or P-100 particulate filter where requested by a worker.

Type 2 Operations (Higher Risk Examples):

• The breaking, cutting, drilling, abrading, grinding, or sanding of the brake pads where they are *not* wetted to control the spread of dust or fibres, and the work is done only by means of non-powered hand-held tools.
• The breaking, cutting, drilling, abrading, grinding, or sanding of the brake shoes where the work is done by means of power tools that are attached to dust-collecting devices equipped with HEPA filters.

Measures and procedures for Type 2 operations (set out in sections 15 and 16 of O. Reg. 278/05) generally include all those required for Type 1 operations, plus additional controls:

• Posting signs warning of the dust hazard.
• Mandatory wearing of respirators.
• The use of wetting agents to control the spread of dust.

Furthermore, employers of workers performing Type 2 operations must complete an asbestos work report in accordance with section 21 of O. Reg. 278/05 and submit it to the Provincial Physician at the Ministry. This report includes the worker's name and the number of hours they may have been exposed to asbestos-containing material.

Employer Duties Under OHSA

Under the OHSA, employers have specified duties to ensure worker safety:

• Awareness of Hazards: Employers must ensure that workers and supervisors are aware of any work hazards and hazards in the handling, storage, use, disposal, and transport of any article, device, equipment, or biological, chemical, or physical agents (section 25(2)(d)).
• Information and Instruction: Employers are required to ensure that workers have received adequate information, instruction, and supervision to protect their health and safety (section 25(2)(a)). For brake maintenance and repair, this may include: the hazards of asbestos exposure through inhalation and ingestion; the measures and procedures to be followed to control exposure; and the use, care, and disposal of personal protective clothing and equipment.
• Reasonable Precautions: Section 25(2)(h) of OHSA requires employers to take every precaution reasonable in the circumstances for the protection of a worker. This often includes establishing written procedures for brake maintenance and repair.

Best Practices for a Safer Workshop

The most effective way to minimise risk is prevention. Employers and mechanics should prioritise the following recommended precautions:

• Use Asbestos-Free Brake Pads: Always order and use aftermarket replacement brake pads that are explicitly confirmed to be asbestos-free. Never assume a product is asbestos-free unless it is clearly stated on the box/container or purchase invoice. This is the single most impactful preventative measure.
• Strict Dust Control: Always use damp cloths or HEPA-filtered vacuums to clean visible dust. Employ impervious drop sheets and dispose of them properly after use. Absolutely avoid using compressed air for cleaning, as this disperses hazardous fibres into the air.
• Personal Protective Equipment (PPE): Ensure appropriate respirators (e.g., N-100, R-100, or P-100 particulate filters) are available and used, especially for Type 2 operations where they are mandatory.
• No Eating or Drinking: Prohibit consuming food or drink, chewing, or smoking in work areas where asbestos exposure is possible to prevent ingestion of fibres.
• Training and Awareness: Provide thorough training on asbestos hazards, safe work procedures, and the correct use and disposal of PPE.

Frequently Asked Questions About Asbestos in Brake Pads

Is asbestos still used in new car brake pads manufactured in Canada?

No, Canadian manufacturers largely ceased using asbestos in brake pads in the late 1980s due to increased awareness of health risks and new occupational health and safety legislation.

Why are imported brake pads a concern if Canadian manufacturers stopped using asbestos?

While domestic production of asbestos-containing brake pads has stopped, significant quantities of aftermarket brake pads containing asbestos continue to be imported into Canada each year, posing an ongoing risk to mechanics and consumers.

How does asbestos exposure occur for mechanics during brake work?

Exposure primarily occurs when fine asbestos dust is released during the removal of dust from brake drums and assemblies, or when brake linings are machined (cut, drilled, abraded, ground, or sanded) before installation.

What diseases are linked to asbestos exposure from brake pads?

Exposure to asbestos fibres can lead to severe occupational diseases, including respiratory problems, asbestosis, lung cancer, pleural plaques, and mesothelioma, a deadly cancer of the lung lining.

How long does it take for symptoms of asbestos-related diseases to appear?

There is a significant latency period for asbestos-related diseases, typically ranging from 10 to 40 or more years between the first exposure to asbestos and the onset of symptoms or diagnosis of the disease.

What precautions should mechanics take to protect themselves from asbestos exposure?

Mechanics should always assume brake pads contain asbestos unless certified otherwise. Key precautions include using wet methods to control dust, employing HEPA-filtered vacuums instead of compressed air, wearing appropriate personal protective equipment like respirators, and following all relevant occupational health and safety regulations (e.g., OHSA in Ontario).

Is Canada going to ban all asbestos in brake pads, including imports?

While domestic manufacturing has ceased, a full ban on the import of asbestos-containing brake pads is actively being pursued through legislation, as evidenced by the bill tabled by an Ontario MPP. The aim is to fully eliminate this hazard from the Canadian market.

Conclusion

The story of asbestos in Canadian automotive brakes is a sobering reminder of the long-term consequences of industrial practices and the persistent vigilance required to protect public health. The devastating toll on former workers serves as a stark warning, while the ongoing challenge of imported asbestos-containing brake pads highlights the need for continued legislative action. As Canada moves towards a complete ban, it is imperative that repair shops, employers, and individual mechanics remain acutely aware of the risks and diligently adhere to best practices and regulatory requirements. Only through a concerted effort can we ensure that the silent killer lurking in brake dust is finally relegated to history, safeguarding the health of those who keep our vehicles running.
