Premium Estimators

Depending on the nature of your business activity, determining your premium can sometimes be a challenge.

To help you learn how to determine your premiums, we’ve built two Premium Estimators that will take you through the various steps involved in calculating your premiums.

Please note:

These estimators are intended to be used as estimates and learning tools only.

If you would like help, or have questions about calculating or reporting your premiums, please call us at 416-344-1000 or 1-800-387-0750 (TTY 1-800-387-0050).
