Effective date


Policy Purpose

Since January 1, 1992, the Workers Compensation Board (WCB) of Manitoba has operated on the basis of a wage-loss system.  A wage-loss system pays a worker based upon the difference between the worker’s average earnings before the accident and what the WCB determines the worker is capable of earning after the accident.  This policy describes the methods that will be used to calculate the worker's post-accident earning capacity.  It applies to workers with accidents occurring on or after January 1, 1992.

Post-accident earning capacity may also affect calculation of benefits payable to workers who were disabled as a result of an accident that occurred prior to January 1, 1992.  This would occur when the worker is receiving rehabilitation benefits, temporary partial disability benefits, or Special Additional Compensation (SAC).  This policy is designed to ensure that his or her post-accident earning capacity is based on similar principles applied to workers who have accidents on or after January 1, 1992.
