We’re lowering the average premium rate for Ontario businesses in 2026 to $1.23 per $100 of insurable payroll, the lowest it has been in more than 50 years.
The 2026 decrease means we’ve cut the average premium rate by more than 50 per cent over the last decade, resulting in cumulative savings for businesses of approximately $21.5 billion since 2016.
Reducing premium rates in 2026 will help businesses save $60 million compared to 2025, as they face ongoing economic uncertainty.

Understanding your 2026 rate(s)
Your 2026 premium rate statement provides you with the following information:
- Your North American Industry Classification System (NAICS) classification.
- Your rate, which is the actual rate you will pay and use to calculate your 2025 premiums throughout the year.
- Your projected rate, which gives the future direction, up or down, that your premium rate is headed if there is no change in your individual and class experience from year-to-year.
Your premium rates for 2026 are set using claims and insurable earnings data as of January 31, 2025. We assign new businesses the class rate of the class/subclass in which they’re placed based on their business activity.
Businesses with projected premium rate increases or decreases will see their rates move up or down a maximum of three risk bands each year from their prior year risk band (approximately 15 per cent),* until they reach their projected premium rate.
*Please note: In rare circumstances, risk band movement may result in a rate change lower or greater than the approximate percentage indicated. The risk band movement approach does not apply to non-profit organizations. Please review our premiums and payments FAQs or non-profit organization policy, for more information.
Maximum insurable earnings
The maximum insurable earnings ceiling for 2026 is $121,700, compared to $117,000 in 2025. Changes to the maximum insurable earnings ceiling are directly linked to changes in average earnings in Ontario as measured by Statistics Canada, and provisions under the Workplace Safety and Insurance Act.
2026 class rates
The following class rates are based on the shared risk of all the businesses that do the same type of work in each class. Your rate reflects your individual experience relative to your class.
Efforts to improve return-to-work and health and safety practices can influence class rate changes over time and you can improve your rate by making your workplace safer.
As a WSIB-registered business, there are many health and safety resources available to you, including free access to the Canadian Centre for Occupational Health and Safety’s Business Safety Portal through our online services and membership to a Health and Safety Association. You can also join our Health and Safety Excellence program to start earning rebates on your premiums.

Non-exempt partners and executive officers in construction
Non-exempt partners and executive officers in construction classified under rate group 755 in our previous rate-setting model continue to receive a separate premium rate. This premium rate reflects the low risk of their work in comparison to the rest of the construction industry. The same premium rate is assigned to all non-exempt partners and executive officers in construction in a given year, although they are classified under any one of the six construction subclasses depending on the operations of their construction business. The 2026 rate for this group is $0.20.
