Pre-Employment Drug and Alcohol Testing in Edmonton

Drug and alcohol testing promotes a safe and secure working environment for employees and their colleagues. By conducting pre-employment and regular drug and alcohol screenings, your organization can deter substance abuse, reducing the risk of accidents, injuries, and potential fatalities. This testing helps to ensure that employees are not impaired while performing safety-sensitive tasks, such as operating heavy machinery or driving company vehicles.

Safe Workspace 

By maintaining a drug-free workplace, your company can improve overall productivity, minimize absenteeism, and enhance employee morale and trust. Additionally, drug and alcohol testing fosters compliance with industry regulations and legal requirements, protecting your businesses from potential liabilities and reputation damage.

Here are five facts about drug and alcohol testing for Occupational Health and Safety (OHS) in the context of Alberta regulations:

Drug and Alcohol Testing 

Drug and alcohol testing in the workplace is sensitive, intersecting with individual privacy rights, safety responsibilities, and labor laws. 

  1. Legal Permissibility: In Alberta, drug and alcohol testing is legally permissible under specific circumstances and with appropriate safeguards to respect workers’ rights. For instance, testing may be allowed in safety-sensitive positions where a demonstrated substance use problem affects the workplace.

  1. Safety-Sensitive Positions: Employers in Alberta can implement drug and alcohol testing policies for workers in safety-sensitive positions, where impairment could result in a significant incident affecting the health and safety of the employee, other workers, the public, the environment, or the employer’s property.
  2. Random Testing: Random drug and alcohol testing is contentious. The Supreme Court of Canada has generally ruled that random testing is not usually permissible unless the employer can demonstrate a generalized problem with substance abuse in the workplace.
  3. Post-Incident Testing: In Alberta, post-incident drug and alcohol testing may be permitted if the incident is significant and there are reasonable grounds to believe that impairment may have contributed to the incident.
  4. Reasonable Cause and Return-to-Work Testing: Employers can implement drug and alcohol testing if there is reasonable cause to believe an employee is impaired at work. Similarly, return-to-work testing might be part of a plan for employees returning after treatment for substance abuse.

These rules can be complex, and your organization must balance the need for a safe work environment with respecting workers’ privacy rights. Your business should work with legal counsel and OHS professionals to ensure their policies are legal and ethical.
