was simply that of employees and employer, involving no corresponding fiduciary obligations and, apart from valid contractual restriction, no limitation upon post-employment competition save as to appropriation of trade secrets and enticement of customers. Decision of the Supreme Court of Canada Appeal was allowed for all but one of the defendants. The Court held that anyone in a supervisory or controlling role of a company has a fiduciary duty towards the company which includes the duties of "loyalty, good faith and avoidance of a conflict of duty and self-interest". As the court noted, Significance The case significantly extended the reach of fiduciary duties that had been previously recognized in Canadian law by Peso Silver Mines Ltd v Cropper, which had adopted the principles of Regal (Hastings) Ltd v Gulliver. These principles have been furthered in subsequent cases, most notably in Peoples Department Stores Inc (Trustee of) v Wise. Aero Service and Peso Silver Mines continue to illustrate the boundaries of conflict of interest that directors of Canadian companies must keep in mind in their deliberations.
