The Toronto ATN site is a collaborative effort between Holland Bloorview Kids Rehabilitation Hospital, Surrey Place and Sick Kids Hospital. Toronto is unique among the 17 sites in that our autism services do not all occur in one location. Together, these 3 institutions work to provide comprehensive autism services with Holland Bloorview providing diagnostic services, Surrey Place delivering specialized treatment (IBI, ABA, OT, BT), and Sick Kids specialists treating some of the comorbid medical conditions . The Canadian sites are also unique in that our services are publicly funded.
