Policy Purpose

Many workers return to employment after a workplace accident and later experience a renewal of symptoms or increase in permanent impairment. In these cases, the Workers Compensation Board (WCB) must determine whether the worker has experienced a recurrence of a previous workplace injury, or whether their current condition is caused by a new and separate intervening event. This policy explains how the WCB determines if the worker has experienced a recurrence. It also provides rules about the calculation of wage loss benefits for workers who have experienced a recurrence.
