At FIREFLY, Applied Behaviour Analysis (ABA) Services are provided to children and youth with a diagnosis of Autism Spectrum Disorder and who are registered with or have applied to the Ontario Autism Program (OAP). ABA Services may be delivered through a variety of options (i.e. in person, virtual or hybrid) where clinicians work directly with the child or youth in the home, centre or community or through the mediator model, where clinicians support family members throughout assessment and intervention.
