Employers in Saskatchewan are grouped based on their industrial undertaking, which is the work, trade or service a business is in. The classification structure consists of three levels: classes, industry groups, and rate codes. Premium rates are set at the rate code level. For example, if your primary business activity is operating a charter bus service, you would be part of the Transportation class, in industry group T4, which is part of rate code T42 – Transportation, Courier, Commercial Bus rate. The classification structure has 10 classes, 33 industry groups and 50 rate codes.
collective liability principle, employers classified in the same rate code contribute in an equitable manner (pay the same industry premium rate) to cover the cost of insurance in their rate code.
