Custom tailored services at home or in-centre

ABA therapy is offered based on a parent’s request for hours and is available to clients presenting to Terrace with or without formal diagnoses. Our integrated team will support each family in seeking a diagnosis and work toward program goals, while advocating for the child in both school placements and in their community. Our IBI service is an intensive program that ideally involves the child participating in a minimum of 25 hours per week of therapy and is done in-centre on a 1:1 basis.

Our ABA and IBI therapy services are custom tailored to meet each individual’s needs. Terrace’s programs are offered to clients 2-18 years of age. To gain the most benefit from ABA and IBI services, it is suggested that the individual receives a minimum of three half-day sessions a week. Services are offered in-centre (morning, afternoon, and some evenings) and in-home (7 days a week).

Applied Behaviour Analysis (ABA) is a science that utilizes behavioural principles to modify socially significant behaviours.  This is a process fueled by reinforcement and motivation. It is through these principles that the Terrace team provides individual ABA therapy to help our clients not only meet, but exceed, goals in communication, social skills, academics, fine motor, gross motor, and self-help/life skills. All of our students are assessed using The Assessment of Basic Language and Learning Skills-Revised (ABLLS-R), which is a widely utilized assessment tool developed by James Partington (PhD, BCBA-D).  Once the ABLLS-R assessment is complete, our collaborative team will work together to create a program that uniquely reflects your child’s needs and goals. An important aspect of our programming focuses on the generalization and maintenance of skills and behaviours to all environments that your child is exposed to.  ABA with Terrace is an inclusive process that includes Psychologists, Senior Therapists, Instructor Therapists and, most importantly, parents. Our goal is to work together as a team to ensure that your child receives the most effective, ethical, enriching, and evidence-based services, allowing them to thrive both in programming and in their lives.


Intensive Behavioural Intervention (IBI) refers to the application of the principles of ABA in an intensive setting. Clients in our IBI program receive ideally a minimum of 25 hours per week of therapy. IBI is delivered on a 1:1 basis or in a small group setting. The goal of IBI is to give children a boost to meet and exceed developmental and academic milestones. IBI also helps children catch up to their peers socially, academically, and developmentally to ensure a smooth transition to school. IBI is best utilized intensively between the ages of 2-6 years of age. IBI also utilizes the ABLLS-R assessment tool to develop programming that best suits each child’s individual needs and goals.

We are now accepting full-time & part-time ABA & IBI clients!

Frequently asked questions

What is the difference between ABA and IBI therapy?

IBI is the intensive version of ABA. Below is an infographic that will explain the main differences.

How long does my child need to be in therapy for?

This is a very difficult question to answer. Every child develops differently, however,  the goal with ABA/IBI therapy is to transition the child from an intensive environment with more support, to a more natural school-based environment, with little to no support. Your child’s progress within the program is closely monitored and as your child progresses, the intensity, duration, and types of therapy required will be adjusted accordingly to meet their needs.

What is Direct Funding Option versus Direct Service Option?

There are two options for receiving services that are available to children on the wait list for IBI treatment:

  • Direct Service Option (DSO) is the option that entitles parents to access treatment from the Regional program, such as CHEO, directly. For DSO clients in our area, CHEO will be the provider of IBI services for your child including execution and monitoring.
  • Direct Funding Option (DFO) is the option to receive funding directly from the Regional program which allows parents to purchase intensive behavioral therapy for their child from private IBI centres such as Terrace Autism Therapy.
