What is the legal test used to determine whether an application has a reasonable prospect of success following a summary hearing?

The approach to deciding whether an application has a reasonable prospect of success following a summary hearing was explained as follows in Dabic v. Windsor Police Service, 2010 HRTO 1994 at paras. 8-10: In some cases, the issue at the summary hearing may be whether, assuming all the allegations in the application to be true, it has a reasonable prospect of success. In these cases, the focus will generally be on the legal analysis and whether what the applicant alleges may be reasonably considered to amount to a Code violation. In other cases, the focus of the summary hearing may be on whether there is a reasonable prospect that the applicant can prove, on a balance of probabilities, that his or her Code rights were violated. Often, such cases will deal with whether the applicant can show a link between an event and the grounds upon which he or she makes the claim. The issue will be whether there is a reasonable prospect that evidence the applicant has or that is reasonably available to him or her can show a link between the event and the alleged prohibited ground.
