About OBSS — Orion for Behavioral & Support Services
We are a team of Board Certified Behavior Analysts and dedicated therapists delivering evidence-based ABA therapy to families across Ontario. Our mission is simple: give every child the expert support they deserve — without the waitlist.
Personalised ABA Therapy, Delivered by Experts Who Care
Our Mission
At OBSS — Orion for Behavioral and Support Services Inc. — we believe every child with autism deserves expert, compassionate support without the barriers of long waitlists or one-size-fits-all programmes. Since 2020, we have been delivering BCBA-supervised Applied Behaviour Analysis therapy to families across Southern Ontario — in their homes, in our Mississauga centre, and in their communities.
Evidence-Based, Child-Centred Approach
Every programme we deliver is designed by a Board Certified Behavior Analyst (BCBA), built around your child's unique strengths and goals, and continuously refined with data collected at every session. We use only approaches recognised by the National Autism Center and the AFIRM.
OAP Approved — We Handle Everything
OBSS is an approved Ontario Autism Program (OAP) provider. We manage all clinical documentation, progress reports, and OAP compliance on your behalf — so you focus on your child while we handle the paperwork.

Every ABA provider in Ontario says they're the best. Here is what we actually do differently — backed by practice, not promises.
Certified BCBA Therapists
Every programme is designed and supervised by a Board Certified Behavior Analyst. Our clinical team brings deep expertise and a genuine commitment to your child's progress.
Personalised Treatment Plans
No two children are the same. We conduct a comprehensive strengths-based assessment before designing a programme tailored specifically to your child's profile and your family's goals.
Data-Driven Progress
We track and measure progress at every session. Written reports keep families informed, and our BCBAs adjust goals continuously based on real data — not guesswork.
Support for the Whole Family
We work closely with parents through training and coaching, providing practical strategies that extend therapy's impact into everyday home and community life.
Flexible Scheduling
Daytime, evening, and weekend sessions available across all service areas. In-home, in-centre, or a blend of both — we build a schedule that fits your family's life.
No Waitlist — Start Now
Ontario ABA waitlists can stretch 12–18 months. OBSS is currently accepting new clients across all service areas with no waitlist. Early intervention leads to the strongest outcomes.
A Full Range of Autism Services Across Ontario
OBSS provides more than ABA therapy. We offer a complete continuum of evidence-based autism support — all coordinated by our BCBA clinical team, all available across our Ontario service areas.
