The signature for CanActivate won't allow you to pass a userRole like you want to. https://github.com/angular/angular/blob/2.0.0-rc.4/modules/%40angular/router/src/interfaces.ts#L54

It's probably best to do separate classes for each of your user role cases. That's the guidance in the official docs too: https://angular.io/docs/ts/latest/api/router/index/CanActivate-interface.html
