The only people who NEED to know about your injury/diagnosis are people who have a direct effect on that injury/diagnosis. Often, this is your medical and rehabilitation team (e.g. Family doctor, Occupational Therapist, Psychologist, Physiotherapist, Naturopath, Chiropodist). If an insurance company, WSIB, and/or lawyer are involved you will be asked to also provide consent to these professionals that will be very involved with your care.
