Ontario Launches Canada’s First Occupational Exposure-Registry to Protect Workers

Purpose of the Occupational Exposure Registry:

The Occupational Exposure Registry is a secure digital portal that allows workers to record and track workplace exposure to hazardous substances throughout their careers.

The main objectives of the registry are to:

  • Help workers document exposures to harmful substances at work.
  • Increase awareness of workplace hazards.
  • Improve data collection on occupational exposures.
  • Support medical assessments if symptoms develop later in life.
  • Strengthen prevention efforts to reduce occupational diseases.

Workers can use a self-tracker tool within the portal to enter information about exposure incidents.

 

How the Registry Works:

Workers can voluntarily submit exposure information through the online registry. Submissions can be completed quickly and include information such as:

  • The hazardous substance involved
  • How the exposure occurred
  • Protective measures used, including:
    • ventilation
    • training
    • personal protective equipment (PPE)

After submitting information, workers receive:

  • A confirmation email
  • A downloadable record of the exposure report.

These records allow workers to maintain a long-term history of exposures that may be important if health issues arise years later.

 

Hazardous Substances Covered:

The registry initially includes 11 designated hazardous substances, including examples such as:

  • asbestos
  • lead
  • mercury
  • silica

These substances are commonly linked to occupational illnesses, particularly in industries such as construction, mining, firefighting, and manufacturing.

 

Why the Registry Is Needed:

Occupational diseases are often difficult to diagnose because there can be long periods between exposure and the appearance of symptoms. This delay can make it difficult for workers to prove the connection between their job and their illness.

By allowing workers to track exposures over time, the registry may help:

  • Provide documented evidence of exposure
  • Assist health-care providers with diagnosis
  • Improve disease prevention and research

 

Relationship to WSIB (Workplace Safety and Insurance Board):

The article notes several ways the registry relates to Workplace Safety and Insurance Board (WSIB).

1. Potential support for WSIB claims

Better documentation of workplace exposures could help workers who later develop occupational illnesses access WSIB services and benefits more quickly.

According to WSIB leadership, improved exposure data may lead to faster access to WSIB supports for occupational disease claims.

2. Data supporting workplace injury and illness claims

Documented exposure histories can assist with:

  • proving workplace causes of illness
  • improving claim assessments
  • supporting workers seeking compensation for occupational disease.

 

Occupational Disease in Ontario:

The article emphasizes the significant impact of occupational illness in Ontario.

Key statistics include:

  • 20,886 occupational disease claims were allowed by WSIB in 2025.
  • Between 2010 and 2019, approximately 76% of workplace fatalities in Ontario were related to occupational illness, not traumatic injuries.

This demonstrates that long-term exposure to hazardous substances is a major cause of workplace deaths in the province.

 

Legislative Background:

The registry was originally promised in the Working for Workers Act, 2023, which introduced several measures aimed at improving worker protections.

The system also responds to recommendations made in Ontario’s Occupational Disease Landscape Review (2023), which called for better tracking and understanding of workplace exposures.

Related Workplace Safety Initiatives in Ontario:

The article places the registry within a larger set of worker protection initiatives introduced through Ontario’s Working for Workers legislative packages.

Examples of related measures include:

  • Requiring properly fitting personal protective equipment (PPE) for workers of different body types.
  • Mandating automated external defibrillators (AEDs) on construction projects with 20 or more workers lasting three months or longer.
  • Requiring naloxone kits in workplaces where opioid overdose risks exist.

 

 

WSIB Investments in Worker Health:

The Ontario government also directed the Workplace Safety and Insurance Board to invest $400 million in health and safety programs.

These investments are intended to support:

  • mental health programs
  • prevention initiatives
  • treatment and recovery programs
  • return-to-work support for injured workers. The goal is to ensure workers receive adequate support so they can recover and safely return to employment.

 

Employer Recognition and WSIB Incentives:

The article also references Ontario’s Supporting Ontario’s Safe Employers (SOSE) program.

This voluntary program recognizes employers that exceed basic safety compliance requirements.

Key details include:

  • 101 employers have been recognized under the program.
  • Participating employers have received more than $4.5 million in incentives from WSIB.

These incentives are designed to encourage employers to invest in workplace safety systems.

 

Broader Impact:

The registry is intended to benefit several groups:

Workers

  • Ability to track exposure throughout their careers
  • Better protection against long-term occupational disease
  • Potential support for WSIB claims if illness occurs later

Health-care providers

  • Access to better exposure history when diagnosing occupational illness

Government and researchers

  • Improved data on exposure trends
  • Better ability to develop prevention strategies

 

Overall Significance:

The article presents the Occupational Exposure Registry as a major step toward preventing occupational disease in Ontario.

The registry aims to:

  • increase awareness of workplace hazards
  • improve exposure documentation
  • support health monitoring
  • enhance prevention efforts
  • strengthen access to WSIB benefits for occupational disease claims.

By collecting exposure data directly from workers and tracking it over time, Ontario hopes to reduce occupational illness and build a safer workforce across the province.
