Ontario Strengthening Occupational Illness Protections

Occupational Exposure Registry, Leadership Table and new report will deliver improved protections for workers

David Piccini, Minister of Labour, Immigration, Training and Skills Development.

The Ontario government is protecting and supporting workers by committing to create Canada’s first-ever Occupational Exposure Registry to track harmful exposure levels, help diagnose workplace diseases faster, improve worker compensation, and reduce costs to the healthcare system. The registry will help address many of the 41 recommendations resulting from the province’s first-ever review of the occupational illness landscape, released in a report today.

“While Ontario has one of the strongest health and safety records of any jurisdiction anywhere, too many workers are falling through the cracks when it comes to occupational illness,” said David Piccini, Minister of Labour, Immigration, Training and Skills Development. “Under the leadership of Premier Ford, our government will leave no stone unturned to ensure we have the best science and data needed to protect workers and make room for everyone’s voice at the table as we build a stronger system that works for everyone.”

Many workplace illnesses currently go undiagnosed or unreported because of the delay between exposure and symptoms, making it difficult to identify occupational disease risks and for workers to get financial support when they fall ill. The new registry would include comprehensive exposure records, identify at-risk workers, help with earlier diagnoses, and potentially contribute to expanding the list of presumptive illnesses in Ontario to improve worker compensation.

“Through our government’s Your Health plan, we are building a healthcare system that better provides Ontarians with the right care, in the right place,” said Sylvia Jones, Deputy Premier and Minister of Health. “With this innovative, first-of-its-kind Occupational Exposure Registry, our government is making it easier for workers across the province to connect to the care and support they need, when they need it.”

In addition, Ontario is creating an Occupational Illness Leadership Table made up of industry experts and worker advocates to guide the implementation of the report’s recommendations. The table will include some of the province’s foremost medical voices along with representatives from workplace health and safety groups to ensure the province keeps pace with advancements in medical science and technology and delivers for workers.

To build the Occupational Exposure Registry, which is expected in 2025, the Ministry of Labour, Immigration, Training and Skills Development is working with the Occupational Cancer Research Centre (OCRC) to collect and analyze data from existing Ministry industrial hygiene records. The Ministry and OCRC are also working with healthcare providers and industry associations to gather new data and catalogue past and current occupational exposures across Ontario’s hundreds of thousands of workplaces.

“The Ontario Federation of Labour (OFL) has long advocated for greatly increased recognition of occupational diseases by Ontario’s workers’ compensation system,” said Patty Coates, OFL President. “A government commissioned study by Dr. Paul Demers recently found that less than 10 per cent of Ontarians with occupational cancers ever get compensated. The OFL welcomes the government proposal to establish an occupational disease registry as a first step towards moving on other key recommendations in the Demers report, such as increasing the number of cancers recognized for workers’ compensation.”

The Occupational Disease Landscape Review report was authored by Dr. Linn Holness and Janet Brown of the MAP Centre for Urban Health Solutions at St. Michael’s Hospital in Toronto, a site of Unity Health Toronto, and an internationally recognized research organization. The 58-page report includes recommendations on workplace prevention and monitoring of occupational disease, healthcare delivery and ways to strengthen connections within the system.

In addition to the Registry, work is underway to deliver on the report’s recommendations, including the development of a web-based Silica Control Tool that will assist in detecting and monitoring workplace silica exposure in the construction and mining industries.

Quick Facts

  • The province recently passed new legislation that increases the maximum fines for businesses that fail to protect their workers and released Ontario’s five-year Prevention Works strategy.
  • The Occupational Illness Leadership Table will be chaired by the Ministry of Labour, Immigration, Training and Skills Development with support from the Ministry of Health.
  • An occupational illness is a condition that results from exposure to a physical, chemical or biological agent in the workplace to the extent that normal physiological mechanisms are affected, and the health of the worker is impaired.
  • There were 40,185 allowed occupational disease claims in 2022, according to the Ontario Workplace Safety and Insurance Board (WSIB).
  • Occupational illness claims totalled $82.5 million in 2022 according to the WSIB.


“Occupational disease is a multi-generational problem and the only way to eradicate it is by monitoring workers’ exposures and health over their lifetimes to identify and eliminate the causes of occupational disease. It took courage to establish the Occupational Exposure Registry, and it will take the courage and commitment of generations to see this through. If we get this right, we will break the cycle of occupational disease – and that makes the loss of my dad easier to bear.”

“I’d like to thank Dr. Linn Holness and Janet Brown for their unwavering commitment to preventing occupational illnesses in Ontario’s workplaces. The recommendations in their Occupational Disease Landscape Review report will help guide the ministry and stakeholders over the next several years so that we bridge the gaps between the province’s occupational health and safety and healthcare systems.”

– Dr. Joel Moody
Ontario Chief Prevention Officer

“The new Occupational Exposure Registry is a big step forward to help answer questions and connect the dots between historic exposures and current illness. It will provide us with valuable information to help make evidence-based decisions to give people the help and support they need.”
