Autism Awareness Month in Ontario: Understanding, Acceptance, and the Role of ABA

April is Autism Awareness Month in Ontario—a time to celebrate the diverse and vibrant autistic community, advocate for meaningful support, and reflect on the evolving journey of autism services, including Applied Behaviour Analysis (ABA).

April 2nd is World Autism Day.

As a Registered Behaviour Analyst, I have the privilege of working alongside individuals on the spectrum, their families, and dedicated professionals who strive to create inclusive, supportive environments. Over the years, I’ve witnessed both the challenges and the triumphs, and I want to take a moment to acknowledge the progress we’ve made while recognizing the work that still lies ahead.

A Brief History of Autism

Autism has always been part of the human experience, though its recognition as a distinct condition is relatively recent. The term "autism" was first introduced in the early 20th century, but it wasn’t until the 1940s that researchers like Leo Kanner and Hans Asperger began to describe what we now understand as Autism Spectrum Disorder (ASD).

The criteria and diagnostic label have changed significantly over the years.

In the decades that followed, our understanding of autism has shifted dramatically—from outdated theories blaming parenting styles to recognizing autism as a neurodevelopmental condition with a broad and diverse spectrum of presentations. Today, we emphasize strengths-based perspectives, inclusion, and self-advocacy, ensuring that autistic voices are at the forefront of conversations about autism support and services.

Autism Awareness vs. Autism Acceptance

For years, Autism Awareness Month focused on making the public more aware of autism. While awareness is still important, the conversation has evolved to emphasize acceptance. Awareness is knowing autism exists; acceptance is creating a world where autistic individuals are valued, included, and supported in ways that respect their unique needs.

Ontario has made strides in this direction, though families, self-advocates, and professionals continue to push for improvements in funding, accessibility, and individualized support. One of the key components of autism services in Ontario is ABA therapy, which has been both a source of support and a topic of discussion within the autism community.

The Role of ABA in Autism Support

Applied Behaviour Analysis (ABA) has been a cornerstone of autism services for decades. It is an evidence-based approach that focuses on understanding behaviour and using individualized strategies to teach new skills, improve communication, and support independence.

Over time, ABA has evolved significantly. Early forms of ABA were rigid and focused primarily on eliminating behaviours, but today’s ABA emphasizes individualized, compassionate, and flexible approaches that align with the unique strengths and needs of each person. Modern ABA prioritizes collaboration, dignity, and respect, ensuring that therapy supports meaningful goals set by the individual and their family.

Compassionate care prioritizes the dignity, autonomy, and well-being of an individual.

The Impact of Autism on ABA—and on Me

Interestingly, just as ABA has shaped autism support, autism advocacy has also shaped ABA. Over the years, autistic self-advocates have voiced concerns about how ABA is practiced, leading to necessary shifts in approach. There has been a move toward naturalistic, play-based, and person-centered ABA, moving away from strict compliance-based methods. Today, many ABA professionals work alongside autistic individuals to refine and improve practices, ensuring therapy is supportive, ethical, and beneficial.

But beyond shaping the field, working with autistic individuals and their families has profoundly shaped me as a person. It has refined my skills—not only in my ABA practice but in everyday communication. My nonverbal clients have taught me to be more attuned to body language, gestures, and subtle cues that often say more than words ever could. Perspective-taking has taken on a whole new meaning as I work to understand the thought processes behind certain behaviours, realizing that every action has a reason, even if it’s not immediately clear.

More than anything, working within this community has deepened my empathy. I see the resilience of families navigating systems that are still catching up, the daily struggles of individuals who are expected to conform to a world that doesn’t always accommodate them, and the small yet significant victories that deserve to be celebrated.

Ironically, as ABA aims to help autistic individuals reach their unique potential, I feel that working with this community has helped me work toward my own. Every day, I learn, grow, and strive to be a better version of myself—because the individuals and families I work with inspire me to do so.

ABA in Ontario: Challenges and Progress

Ontario has a unique landscape when it comes to autism services. The Ontario Autism Program (OAP) has undergone significant changes in recent years, impacting funding and access to ABA. Families often face long waitlists, financial barriers, and inconsistent services depending on where they live.

Despite these challenges, ABA professionals in Ontario continue to advocate for high-quality, ethical, and accessible services. We are seeing increased collaboration between ABA providers, educators, speech-language pathologists, occupational therapists, and, most importantly, autistic individuals themselves. This teamwork helps create holistic, well-rounded supports that go beyond behaviour to foster independence, self-advocacy, and meaningful engagement in the community.

Moving Forward: What Can We Do?

Autism Awareness Month is more than just a time to wear blue or share facts—it’s a chance to actively contribute to a more inclusive Ontario. Here’s how we can all help:

1. Listen to autistic voices – Whether it’s reading books by autistic authors, following autistic self-advocates on social media, or engaging in conversations, learning directly from autistic individuals is invaluable.

2. Advocate for better services – Continued improvements to the OAP, education supports, and employment opportunities require collective advocacy. Supporting policies that fund evidence-based, individualized services benefits the entire community.

3. Encourage acceptance and inclusion – Small changes, like using identity-affirming language, making workplaces more neurodivergent-friendly, and fostering inclusive classrooms, create a more welcoming society.

4. Support families and caregivers – Parenting a child with autism comes with unique joys and challenges. Offering understanding, resources, and emotional support can make a world of difference.

Final Thoughts

As we celebrate Autism Awareness (and Acceptance) Month in Ontario, let’s remember that our ultimate goal is a world where every autistic individual is respected, understood, and empowered. ABA is just one of many supports that, when practiced ethically and compassionately, can play a role in helping individuals reach their own unique potential. This April, let’s commit to learning, listening, and growing together—because when we embrace neurodiversity, we build a better, more inclusive world for everyone.
