If a firefighter or a fire investigator is diagnosed with a prescribed cancer on or after January 1, 1960, and meets the employment duration and additional criteria for the prescribed cancer, then the disease is presumed to be an occupational disease due to the nature of the worker’s employment, unless the contrary is shown.
The purpose of this policy is to outline the prescribed cancers and the circumstances under which they will be presumed to be work-related occupational diseases, as set out in the applicable Regulation, as well as to specify the circumstances in which the contrary will be shown and the presumption of work-relatedness rebutted.
This policy applies to:
- workers who are full-time or volunteer firefighters as defined in Section 1 of the Fire Protection and Prevention Act, 1997
- part-time firefighters, defined as a worker who is a firefighter and is not a volunteer or full-time firefighter
- workers who:
- are employed by a band council and assigned to undertake fire protection services on a reserve [band council and reserve are defined in the Indian Act (Canada)], or
- provide fire protection services on a reserve, either voluntarily or for a nominal consideration, honorarium, training or activity allowance
- fire investigators, defined as a worker:
- to whom the Fire Marshal, appointed under subsection 8(1) of the Fire Protection and Prevention Act, 1997, has delegated the duty to investigate the cause, origin and circumstances of a fire
- who was an inspector appointed under subsection 2(4) of the Fire Marshals Act before that Act was repealed by the Fire Protection and Prevention Act, 1997, or
- who is employed by a band council and assigned to investigate the cause, origin and circumstances of a fire on a reserve.
For the purpose of this policy, the term "firefighter" refers to a full-time firefighter, a part-time firefighter or a volunteer firefighter.
This policy does not apply to forest or wildland firefighters.
The presumption provides that the prescribed cancers are occupational diseases presumed to occur due to the nature of the worker’s employment as a firefighter or fire investigator, unless the contrary is shown.
To qualify for this presumption, a worker must meet the inclusion criteria of this policy and have been:
- diagnosed with a prescribed cancer
- diagnosed after the prescribed minimum employment duration, and
- diagnosed with that cancer on or after January 1, 1960.
A worker diagnosed with primary-site colorectal cancer or primary-site lung cancer must also meet the additional criteria specified in this policy to qualify for the presumption.
A worker who does not meet these criteria does not qualify for the presumption and instead will have their claim determined on its individual merits.
A medical diagnosis of non-Hodgkin’s lymphoma, multiple myeloma, one of the three specified leukemias, or cancer originating from the specified organ is required for adjudication of claims under this policy. The prescribed cancers are listed below with their World Health Organization classification numbers.

Prescribed duration of employment
Firefighters and fire investigators with the minimum years of eligible Ontario service for the prescribed cancer are presumed to have a work-related occupational disease. The eligible years of service is the sum of all employment periods as a firefighter or fire investigator from the date of hire until the date of diagnosis, whether consecutive or non-consecutive. If a worker served in more than one capacity as a full-time, part-time or volunteer firefighter or fire investigator in the same period, this period will only be counted once towards the eligible years of service.
For band council firefighters and fire investigators, the eligible years of service are those employment periods as described above during which the band council had WSIB coverage, in addition to any periods served in another capacity as defined by the Fire Protection and Prevention Act, 1997.
The minimum durations of employment for the prescribed cancers are listed below.
|Prescribed Cancer||Duration of Firefighting Employment|
|1. Primary-site brain cancer||10 years|
|2. Primary-site bladder cancer||15 years|
|3. Primary-site kidney cancer||20 years|
|4. Primary-site colorectal cancer||10 years|
|5. Primary non-Hodgkin’s lymphoma||20 years|
6. Primary acute myeloid leukemia
|7. Primary-site ureter cancer||15 years|
|8. Primary-site esophageal cancer||25 years|
|9. Primary-site breast cancer||10 years|
|10. Multiple Myeloma||15 years|
|11. Primary-site testicular cancer||10 years|
|12. Primary-site prostate cancer||15 years|
|13. Primary-site lung cancer||15 years|
|14. Primary-site skin cancer||15 years|
|15. Primary-site ovarian cancer||10 years|
|16. Primary-site cervical cancer||10 years|
|17. Primary-site penile cancer||15 years|
In addition to the above criteria, for:
- primary-site colorectal cancer, a diagnosis must be obtained prior to the age of 61 years
- primary-site lung cancer, the worker must not have smoked a tobacco product in the 10 years prior to diagnosis.
Date of accident/injury
For the purpose of this policy, the date of diagnosis is used to determine whether the worker meets the requirements of the presumption (e.g., calculation of duration of employment). Once entitlement is established in a claim, benefits and services generally flow from the date of accident/injury, which may be an earlier date. For more information, see 11-01-04, Determining the Date of Injury.
Rebutting the presumption
If a worker qualifies for the presumption, the worker’s cancer is presumed to be an occupational disease that occurs due to the nature of the worker’s employment as a firefighter or fire investigator, unless the contrary is shown. If the contrary is shown, the presumption of work-relatedness is rebutted.
The presumption is only rebutted if the evidence establishes on a balance of probabilities that:
- the worker either had negligible exposure or was never exposed to the hazards of a fire scene or to another known occupational risk factor for their cancer during their employment as a firefighter or fire investigator, or
- the worker’s non-occupational risk factors were of such importance that they overwhelmed any occupational exposure the worker had as a firefighter or fire investigator, rendering it insignificant in the development of the worker’s cancer.
Examining whether the presumption is rebutted
It is not necessary to examine whether the presumption is rebutted in every case. Generally, if a worker qualifies for the presumption, an examination into rebuttal is only necessary if the existing evidence in the claim raises a question about whether the worker’s cancer is due to the nature of their employment as a firefighter or fire investigator. For instance, there may be a question about work-relatedness when the nature of the worker’s job does not involve regular exposure to the hazards of a fire scene.
If the presumption is rebutted, the worker’s cancer may still be work-related if the worker’s job history includes other types of employment. In these cases, the worker’s job history, outside of their employment as a firefighter or fire investigator, should be examined to determine if there is a work-related cause.
Workers or their survivors may refile previously denied claims, or present new claims, with no time restrictions other than a requirement that the date of diagnosis is on or after January 1, 1960.
The six-month time limit for filing a claim applies to claims in cases where the worker does not qualify for the presumption or where the presumption has been rebutted, see 15-01-03, Workers' Requirement to Claim and Consent.
