What is the test for a motion for an interim injunction?

I am mindful that the jurisprudence recognizes considerable latitude to judges deciding matters such as these, given the factual dimension of the dispute and of the largely discretionary character of the decision to grant or refuse the order requested, and that, generally speaking, these considerations do not favour leave being granted: see, e.g., Jenbaz v. Daoud, 2016 QCCA 896 (Morissette, J.A., in chambers). I am mindful too that the presiding judge here has been named case management judge in this dispute, and that his carefully written opinion contains no apparent error in the identification of the three criteria applicable to a request for an injunction at this stage.
