text: The statement is good law. The law, for instance, on peace bonds requires that the person on whose behalf the peace bond is sought have objectively reasonable grounds to fear for their safety.  Canadian law on self defence requires that you have objectively reasonable grounds to use force in your own defence. "I felt threatened" is not sufficient. There appears to be a widespread de facto exception to the requirement for objectively reasonable grounds in American law. A police officer can shoot an unarmed victim and justify it on the basis that "I felt threatened" or "I felt that my life was in danger." I am aware of no such exception to the requirement for objective reasonability in Canadian law.
  
  As for Ross, that fits neatly into the exception I noted about employee off-work conduct that reflects adversely on the employer.
