This article describes the benefits of a study on social participation of young adults who grew up with deaf parents in terms of clinical services provided to these families at the Quebec City Rehabilitation Institute (Institut de réadaptation en déficience physique de Québec or IRDPQ)and reviews the actions undertaken by the clinical team in order to set up an association for CODA (Children of Deaf Adults) in the province of Quebec. This study confirms the relevance of homework assistance services offered to school age children. Moreover, the team speech therapist’s scope of action was expanded; the language capacities of hearing children are now assessed both in French and QSL. This further promotes the use of QSL and enhances the hearing child’s role in the transmission of their deaf parent’s language. However, this case study highlights the needs of adult CODAs that are not being met by rehabilitation services, particularly at a psycho-social level. Approaches leading to the creation of an association for CODA (called CODA Québec) were initiated at the end of 2008 through a seminar involving 65 participants (deaf people, CODAs and hearing spouses). Subsequently, with the support of IRDPQ, the association’s legal requirements were determined and collaborations with the deaf community were established by the end of 2009. The establishment of CODA Québec has not only had direct effects on clinical interventions, but has also allowed stakeholders to identify a need as well as the means to respond, which will ultimately allow codas to recognize and support each other.
