Renfrew Insurance Ltd. v Cortese, 2014 ABCA 203:
 The test for an interlocutory injunction is well established and not in dispute. It has three components (RJR McDonald Inc v Canada (Attorney General), 1994 CanLII 117 (SCC),  1 SCR 311):
(i) a strong prima facie case, in cases of employees restrictive covenants, or a serious issue to be tried;
(ii) irreparable harm before trial if no injunction is granted; and
(iii) the balance of convenience must favour the granting of the relief.
 In assessing whether a strong prima facie case exists, the court is obliged to consider the enforceability of the restrictive covenants in question. However, a prolonged examination of the merits of a case at the interlocutory stage is neither necessary nor desirable: RJR-MacDonald at 337-38.
