2023 premium rates

The average premium rate for Ontario businesses in 2023 remains steady at $1.30 per $100 of insurable payroll, the lowest it has been in more than 20 years, building on our support to help Ontario businesses recover from the COVID-19 pandemic.

The fastest and easiest way to view your 2023 premium rate is through our online services. Your statement will be available online starting November 1 and will be mailed to you later this fall.  

Accessing your statements

Starting in January 2023, we will no longer mail paper statements of account, premium rate statements or claim detail statements. Your WSIB account statements will be available exclusively through our online services.

Reading your 2023 statement

Your 2023 statement provides you with the following information:

  1. Your North American Industry Classification System (NAICS) classification
  2. Your rate, which is the actual rate you will pay and use to calculate your 2023 premiums throughout the year
  3. 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

2023 premium rates are set using claims and insurable earnings data as of May 31, 2022. New businesses are assigned the class rate of the class/subclass they are placed in based on their business activity. 


As part of our approach to smoothly transition to our new rate-setting model first introduced in 2020, any projected decreases will be applied to your rates in 2023. Businesses with a projected premium rate increase due to their individual and/or class risk and experience will move up a maximum of two risk bands (approximately 10 per cent) from their 2022 rate.*

Starting in 2024, our policies for premium rate setting under our new rate-setting model will be fully in effect. 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: This transition approach does not apply to temporary employment agencies or non-profit organizations. Please see our premiums and payments FAQs, temporary employment agency rate setting consultation or non-profit organization policy, for more information.  

*In rare circumstances, risk band movement may result in a rate change lower or greater than the approximate percentage indicated. Please see our premiums and payment FAQs for more information.

Maximum insurable earnings

The maximum insurable earnings ceiling for 2023 is $110,000, compared to $100,422 in 2022. 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. Amendments made to the Workplace Safety and Insurance Act in 2021, which gave the Government of Ontario regulation-making authority to set the maximum insurable earnings ceiling for 2022, are not applicable in 2023.

Non-exempt partners and executive officers in construction

Non-exempt partners and executive officers in construction who were 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 2023 rate for this group is $0.13.
