About Deaf Interpreting

two people signing and one person attentive


A Deaf Interpreter (DI) is a specialist who provides interpreting services in American Sign Language, langues des signes québécoise (LSQ), and other visual and tactual communication forms used by individuals who are Deaf, hard of hearing, and deafblind.

As a Deaf person, the Deaf Interpreter starts with a distinct set of formative linguistic, cultural, and life experiences that enables nuanced comprehension and interaction in a wide range of visual language and communication forms influenced by region, culture, age, literacy, education, class, and physical, cognitive, and mental health. These experiences coupled with professional training give the Deaf interpreter the ability to effect successful communication across all types of interpreted interactions, both routine and high risk.

CHS accredited Deaf Interpreters are active members of the national professional association: Canadian Association of Sign Language Interpreters (CASLI). They have completed mandatory trainings and commit to abide by the Code of Ethics and Guidelines for Professional Conduct. 

CHS accredited Deaf interpreters have successfully completed CHS Interpreting Services’ rigorous testing and accreditation process. CHS also provides ongoing training including advanced interpreting, ethical practice, and legislated mandatory trainings, such as the AODA, etc.
