Personalised, play-based ABA programs for children with autism — delivered in your home or at our Mississauga centre. BCBA-supervised, OAP-approved, and built around your child's unique goals.
OBSS supports autistic children and youth across Mississauga — from toddlers through to teens. We also partner with families exploring assessment or currently waiting for other services. Our team collaborates with caregivers, schools, SLPs, OTs, and paediatricians to build skills that matter at home, at school, and in the community.
OBSS's head office and therapy centre is located at 39 Dundas St E, Suite 206, Mississauga — near Cooksville and a short drive from Square One. Our centre provides a structured, resource-rich environment ideal for school readiness programs and peer interaction sessions.
Every programme is designed by a Board Certified Behavior Analyst (BCBA) and continuously monitored with data-driven adjustments and regular written progress reports.
