Direct answer
Quick AnswerPlay-based interventions for autistic children encompass several evidence-supported approaches: child-centred play therapy, integrated play groups (Wolfberg, 2003), and developmental play models like DIR/Floortime and ESDM. Research by Kasari et al. (2006) demonstrated that joint attention and symbolic play interventions improve engagement and language outcomes. In Ontario, play therapy is available through registered psychologists, child therapists, and some OAP-approved providers.
Start with the short answer, then reveal deeper context where helpful.
Play-based autism interventions range from structured programs (integrated play groups, ESDM) to less directive approaches (child-centred play therapy). Integrated Play Groups (Wolfberg, 2003) pair autistic children with typical peers in facilitated play sessions, with strong evidence for increasing symbolic play and social interaction. Kasari et al. (2006) showed that targeted joint attention and symbolic play interventions led to significant gains in joint engagement and expressive language.
In Ontario, play therapy is offered by registered psychologists, registered psychotherapists, and registered social workers with specialized training. Costs for private play therapy sessions typically range from $120-180/hour. Some community mental health agencies offer subsidized play therapy programs.

Child-centred play therapy uses a non-directive approach where a therapist follows the child's lead in a playroom, reflecting feelings and building the therapeutic relationship. While less specific to autism, it can address anxiety, emotional regulation, and self-expression — common needs in autistic children.

Under OAP, play-based interventions that are evidence-based and delivered by approved providers may be funded through core clinical budgets. DIR/Floortime and ESDM, which are play-based, can be covered when delivered by qualified OAP providers. General child-centred play therapy may not be directly covered unless incorporated into a broader clinical plan.

Compare DIR/Floortime (relationship-based) and ABA (behaviour-based) autism therapies. Both are valid approaches with different philosophies and evidence bases.
