In November 2016, the Board of Directors of Ontario’s Workplace Safety and Insurance Board (the “WSIB”) approved a new premium rate framework (the “Framework”) that is expected to come into effect in January 2019. The changes have been proposed to address the “fundamental challenges to the WSIB’s current classification and premium rate setting approach” that have been identified by the WSIB and its stakeholders. The Framework will have significant implications for employers with respect to how premiums are calculated. Employers will be classified differently in an effort to create a structure that is simple and understandable. One of the most significant changes relates to an employer’s experience rating. Currently, an accident or injury affects an employer’s premiums for a period of four years. Under the Framework, accidents or injuries will affect an employer’s premiums for a period of six years. Although the Framework has been approved, the WSIB has indicated that the plan is flexible, adaptable and will be responsive to further stakeholder engagement.
