Earlier this year, the Supreme Court of Canada (SCC) refused the union’s leave application in Suncor Energy Inc v Unifor Local 707A, 2017 ABCA 313 (Suncor ) thereby leaving the Alberta Court of Appeal’s (ABCA) ruling intact. The ABCA had held that evidence of substance-related safety risks across an employer’s workforce (including both union and non-union workers) may be taken into account when assessing the permissibility of random testing of unionized workers.
Suncor is a favourable result for employers because it is in step with taking a holistic approach to workplace safety. But it is by no means a green light for drug and alcohol testing in the workplace. With the legalization of recreational use of cannabis fast approaching, we outline the current state of the law and key best practices for workplace impairment testing.
