The Manitoba Court of Appeal has recently released a case dealing with vicarious liability of an employer for sexual assault by one of its employees. The Court provides a useful summary of the principles used in determining vicarious liability, as well as a summary of case law involving employers.
In Robertson v. Manitoba Keewatinowi Okimakanak Inc.,  M.J. No. 24 (C.A), the plaintiff was an executive assistant who made plans at work with her supervisor (Hart) to socialize after work to celebrate her birthday. They went to a restaurant for dinner and then to Hart’s residence where he sexually assaulted the plaintiff. The plaintiff notified the employer about the assault, who investigated the incident and terminated the Hart’s employment. The plaintiff sued both the Hart and the employer. The employer was successful in a motion to strike the Statement of Claim and the plaintiff appealed.
The test for a finding of vicarious liability was set out by the Supreme Court in Bazley v. Curry,  2 S.C.R. 534, which the Manitoba Court of Appeal summarized as follows:
1. The test for vicarious liability should focus on whether the employer’s enterprise and empowerment of the employee materially increased the risk of the sexual assault and hence the harm;
2. The enterprise and employment must not only provide the locale or the bare opportunity for the employee to commit a wrong, it must materially enhance the risk in the sense of significantly contributing to it;
3. The appropriate inquiry is whether the employee’s wrongful act was so closely connected to the employment relationship that the imposition of vicarious liability is justified in policy and principle;
4. In determining the sufficiency of the connection between the employer’s creation or enhancement of the risk and wrong complained of, subsidiary factors will be considered such as a) the opportunity that the enterprise afforded the employee to abuse his/her power; b) the extent to which the wrongful act may have furthered the employer’s aims; c) the extent to which the wrongful act was related to friction, confrontation or intimacy inherent in the employer’s enterprise; d) the extent of power; and e) the vulnerability of potential victims to wrongful exercise of the employee’s power.
5. An incidental attack by an employee that merely happens to take place on the employer’s premises during working hours will scarcely justify holding the employer liable because such an attack is unlikely to be related to the business the employer is conducting or what the employee was asked to do, and, hence, to any risk that was created.
The court held that the facts did not support a finding that the employment went beyond providing a bare opportunity, noting that the assault did not occur in the workplace or during work hours, there was no allegation of inappropriate behaviour on prior occasions, there was no allegation that Hart exercised any power in relation to the plaintiff beyond that which is required in every supervisory position, and there was no allegation that the plaintiff was particularly vulnerable to the wrongful exercise of the Hart’s power.
