What is the test for determining whether a person’s employment was a contributory factor in their personal injury?

The Act does not require that a worker’s employment be the sole cause of his or her personal injury. It is well-established that the accepted injury need not be the only cause or even the most significant cause of a subsequent injury or condition, for the subsequent injury or condition to be compensable (Chima v. Workers’ Compensation Appeal Tribunal, 2009 BCSC 1574, Schulmeister v. British Columbia (Workers’ Compensation Appeal Tribunal), 2007 BCSC 1580). As further explained in policy item #C3-14.00, both employment and non-employment factors may contribute to an injury. The employment factors need not be the sole cause of an injury. For an injury to be compensable, the employment has to be of causative significance, which means more than a trivial or insignificant aspect of the injury.
