Canadian Hearing Services was founded in 1940 to provide services for people in Ontario. Services include instruction in American and Quebec sign languages, interpreter services, deafblind intervenors, audiology and speech-language pathology. The CHS advocates for the hearing impaired in Canada through the support of 9-1-1 texting, visual fire alarms, and access to the justice system. The CHS handles emergency situations in hospitals, emergency rooms, after-hours clinics, shelters, and police services.
