My boss recently told me that I was not being given any more shifts than my one day per week, due to the fact that I was male (she is female). She then hired a new female worker, giving her all the shifts that should rightfully be mine.

Her reason behind her not wanting me to work was because she "didn't want there to be more men working than women" [exact quote].

Could I file a lawsuit against my employer because of this, according to Canadian law?
