Those costs (never paid I believe) were only awarded because JY filed, withdrew, and re-filed the complaint several times, so in answer to would costs be owing to the defendants, costs weren't due to loosing a case, as the case was never bought.
See page 24, part [84] and [87] copied below:
[84] I have found that JY’s pattern of filing a large number of complaints and then withdrawing those where the respondent mounts a defence is improper. In all of the circumstances, I find that a nominal costs award is appropriate to convey this Tribunal’s disapproval of JY’s conduct. I take into account that the issue that JY is pursuing is an important one, that her motivations are complex, that I have made no findings of fact, and that she is self‐ represented. I order her to pay Laser Cut the sum of $150.
[87] JY’s application for costs against Laser Cut is dismissed.
