2018 preliminary rates

WorkSafeBC announces that the average base rate for 2018 is projected to drop from 1.65% to 1.55% of employers' assessable payroll.

Lower claims costs and strong investment returns have enabled us to lower the average rate for 2018.

Together with worker and employer stakeholders, we're working to reduce serious injuries and enhance return-to-work opportunities. In doing this, we can collectively help to prevent injuries, improve return-to-work outcomes, and ultimately lower insurance rates.

The Workers Compensation Act requires WorkSafeBC to set premium rates annually for employers in order to pay for the workers' compensation system.

Employers are placed in one of 547 classification units with other similar businesses. These classification units are then placed into one of 54 insurance pools we refer to as rate groups.

Employers in each rate group pay the costs of injuries and diseases that occur to the workers within the group, with the intent that each rate group be self-sufficient with regard to compensation costs. This limits cross-subsidization between industries, maintains relatively stable insurance rates, and limits growth of unfunded liabilities in the rate groups.

Each year, costs in some rate groups go up, some go down and others stay the same. In 2018, 63% of employers in B.C. are projected to experience a decrease in their industry base rate, 11% will see no change, and 26% will see their industry base rate increase.

Examples of industries with rate decreases include: Waterfront Industries, Local Government, Commercial and Residential Construction, Trucking, Courier, Ranch, Auto Dealerships, Oil Refining, Dairy Farming, Convenience Stores, Home Improvement Centres, General Retail, and Universities.

Examples of industries with rate increases include: Pre-hospital Emergency Health Care, Construction or General Labour Supply, Veterinary Hospital, Multimedia Services, Physiotherapy, Occupational Therapy, Community Health Support Services, Hospitals, and Auto Parts Supply.

Example of industries with little to no change to their rates include: Alcohol or Drug Treatment Centres, Prefabricated Log Home Kit Mfg, Consulting Engineering, Law Offices, Aviation or Flying School, Graphic Design, Financial Services, and Chamber of Commerce.

WorkSafeBC publishes two measures of the overall "average rate.” The first measure is the "published base premium rate" which is released at the time that rates for the upcoming assessment year are announced. This is an estimate based on long term payroll growth expectations. The second measure is the "aggregate premium rate" which represents the actual premiums paid by employers expressed as a percentage of their actual payrolls


Assessment year 2014 2015 2016 2017 2018
Published base premium rate* 1.70% 1.70% 1.70% 1.65% 1.55%
Aggregate premium rate* 1.63% 1.62% 1.62% n/a n/a

*Note: rates are expressed as a percentage of assessable payroll

Here is a more in-depth description of these average rates:

Published base premium rate

This rate is the average base premium rate communicated as a news release each autumn once the Board of Directors has approved the industry base premium rates for the upcoming assessment year. It represents a composite of all the individual industry base premium rates published by WorkSafeBC averaged on the basis of estimated long term industry payroll growth trends. Once the rates for the upcoming assessment year have been approved by the Board of Directors, the corresponding published base premium rate does not normally change — the exception is on those rare occasions when some individual industry rates get retroactively changed after the initial approval as a result of exceptional circumstances.

Aggregate premium rate

This rate is the composite of the individual industry base premium rates published by WorkSafeBC averaged on the basis of the actual payrolls reported by employers for the assessment year. In addition, the aggregate premium rate is adjusted for:

  • Any net imbalance created by the experience rating plan
  • Any premium shortfall created by base rate transition rules
  • Any pre-2000 surplus or interest on that surplus credited to employers in the assessment year to reduce the net amount of premium payable to WorkSafeBC

This is equivalent to expressing the actual total collected premiums for the assessment year as a percentage of the actual total assessable payroll for that same assessment year. The most recent figure quoted for the aggregate premium rate is based upon anticipated premiums and payrolls, and will in general be revised in the following year, once actual premiums have been paid and actual payrolls have been reported.
