In Ontario the majority of workers are employed by employers insured under a collective liability scheme known as “Schedule 1”. These workers are generally prohibited from suing their own employer for workplace injuries or from suing other employees, directors and officers of their employer.
For instance, in a car accident, a person can have post-traumatic stress disorder (PTSD) for a long time and suffer from it even after their wounds are healed. You can sue your employer or any party in Canada for causing emotional distress.
