If you’ve been told that Exposure and Response Prevention is the most effective treatment for OCD, you’re probably wondering what it actually looks like — especially when it happens through a screen.
I get this question constantly from people reaching out for the first time: “Can online therapy really work for something as specific as OCD?” It’s a reasonable concern. ERP involves doing things that feel uncomfortable, and you’d think that requires being in the same room as your therapist.
But the research tells a different story. And my own clinical experience — including training alongside OCD specialists at CAMH — confirms it: virtual ERP isn’t just adequate. For most people, it’s the better format. Let me explain why, and walk you through exactly what happens in sessions.
What ERP Is (And What It Isn’t)
Exposure and Response Prevention is a specialised form of Cognitive Behavioural Therapy (CBT) designed specifically for OCD. It has two components:
Exposure: Gradually and deliberately confronting the thoughts, images, situations, or objects that trigger your obsessions.
Response Prevention: Choosing not to perform the compulsive behaviour that normally follows the trigger.
Here’s the key insight that makes ERP work: when you perform a compulsion, you get temporary relief — but you also teach your brain that the trigger was genuinely dangerous. The compulsion reinforces the obsession. ERP breaks that loop by letting your brain learn, through direct experience, that the anxiety decreases on its own without the ritual.
Think of your anxiety like a smoke alarm that’s been misfiring. Right now, it goes off every time you burn toast. ERP doesn’t remove the alarm — it recalibrates it so it only responds to actual fires.
What ERP is not: it’s not talk therapy where you process the meaning of your intrusive thoughts. It’s not relaxation training. And it’s not your therapist telling you to “just stop” doing your compulsions. It’s a structured, collaborative process where you gradually build evidence that you can handle discomfort — and your brain adjusts accordingly.
If you want to understand how ERP fits into the broader landscape of OCD treatment, my service page covers the full picture.
Why Virtual ERP Actually Has an Advantage
This is the part that surprises most people. Virtual ERP isn’t just “as good” as in-person — it has specific structural advantages for OCD treatment.
Your therapist goes where your OCD lives
In a traditional office, you’d describe your triggers and maybe practise some imaginal exposure. But OCD doesn’t live in a therapist’s office. It lives in your kitchen, your bathroom, your bedroom, your car.
Virtual sessions mean I can guide you through exposure exercises in the actual places where your compulsions happen. If your OCD involves checking the stove, we do the exposure at your actual stove. If it involves contamination fears around your bathroom, we work there. The skills you build translate directly to real life because you’re building them in real life.
The research backs this up
A large-scale study published in the Journal of Medical Internet Research (JMIR) examined treatment outcomes for over 3,500 adults with OCD — the largest reported treated cohort at the time. Virtual ERP produced significant symptom reduction with a large effect size (g=1.0), comparable to the best in-person studies. Participants achieved results in less than half the total therapist time compared with standard outpatient treatment.
More recent 2025 research published in JMIR specifically examining teletherapy for OCD confirmed that remote video treatment shows noninferiority to traditional in-person delivery — including for children and adolescents.
Practical barriers disappear
No commute. No parking. No waiting room anxiety. No need to live near a specialist. These might sound like minor conveniences, but for someone with OCD — where avoidance is already a pattern — removing practical barriers to starting treatment is genuinely important. I serve clients across all of Ontario, from Toronto to Ottawa to Northern Ontario communities that would otherwise have no local access to ERP-trained practitioners.
What Your Virtual ERP Sessions Actually Look Like
Here’s the honest, session-by-session picture of what to expect. No surprises, no sugarcoating.
Sessions 1–3: Understanding your OCD
We start by mapping your specific OCD patterns. I’ll ask about your intrusive thoughts, your compulsions (including mental ones that others can’t see), what you avoid, and what you’re afraid will happen if you don’t perform your rituals. This isn’t small talk — it’s the clinical foundation that everything else builds on.
I know that talking openly about intrusive thoughts can feel terrifying. Many of my clients have never said their obsessions out loud before. I want you to know: I’ve heard it all, and nothing you share will shock me or change how I see you. OCD thrives on secrecy, and naming the thoughts is already part of weakening their grip.
We’ll also spend time on psychoeducation — helping you understand why your compulsions make OCD worse, not better. This isn’t academic. Once you genuinely understand the mechanism, the motivation for exposure work clicks into place.
Sessions 3–5: Building your exposure hierarchy
Together, we create a ranked list of your OCD triggers — from mildly uncomfortable to the most anxiety-provoking. This becomes your roadmap.
For someone with contamination OCD, the lower end might be touching a clean doorknob and waiting five minutes before washing. The higher end might involve eating food after touching a public surface. For someone with perfectionism-related OCD, the lower end might be sending an email with a minor typo, while the upper end involves submitting work without reviewing it.
This hierarchy is collaborative. You’re never pushed into anything you’re not ready for. We start at the bottom and work up, building confidence with each step.
Sessions 5–16+: Active exposure work
This is where the real change happens. We work through your hierarchy, starting with easier exposures and gradually moving toward harder ones.
During virtual sessions, I can guide you in real time. If we’re working on checking OCD, I might ask you to walk to your front door, look at the lock once, and then walk away — while I’m right there with you on screen, coaching you through the urge to go back. If we’re working on contamination fears, I might guide you to touch a surface in your kitchen and sit with the discomfort rather than washing.
The types of exposure we use depend on your OCD:
In-vivo (real-life) exposure — directly confronting feared situations in your actual environment. This is where virtual therapy shines, because we’re already in your space.
Imaginal exposure — vividly describing or visualising feared scenarios. This is especially useful for harm OCD and intrusive thoughts where the fear involves something you can’t physically recreate.
Response prevention practice — learning specific strategies for resisting compulsions in the moment: delaying, observing the urge without acting, tolerating the discomfort.
Ongoing: Building independence
The goal of ERP isn’t to need me forever. It’s to teach you to become your own therapist. As you progress, sessions shift from guided exposure toward relapse prevention: recognising early warning signs, maintaining a self-directed exposure practice, and knowing when to schedule booster sessions.
What Success Actually Looks Like
I want to set realistic expectations, because myths about OCD treatment can set people up for disappointment.
ERP success doesn’t mean you’ll never have an intrusive thought again. It means intrusive thoughts lose their power. They become background noise rather than emergencies. Compulsions shrink from hours to minutes to nothing. You get your time and energy back.
Research suggests that roughly 80% of people who complete ERP see significant symptom reduction. Most of my clients notice improvement within the first 6–8 sessions, with the most meaningful changes typically happening by sessions 12–20.
And unlike medication alone — which manages symptoms while you take it — the skills you learn in ERP stay with you. You’re not just feeling better temporarily. You’re building a fundamentally different relationship with uncertainty.
Homework Matters (More Than You Think)
I’ll be straightforward about this: ERP only works if you practise between sessions. The 50-minute session is the training ground. The real work happens in the other 167 hours of your week.
Between sessions, I’ll assign specific exposure exercises — things like touching designated surfaces without washing, leaving the house without checking, or allowing intrusive thoughts without performing mental rituals. I ask clients to track their anxiety levels during these exercises so we can see the pattern over time: what starts at an 8/10 in week one often drops to a 3/10 by week four.
This is where your commitment matters most. Clients who consistently do their homework between sessions progress significantly faster than those who don’t. It’s not about being perfect — it’s about being consistent.
Common Concerns Before Starting
“What if I panic during a session?” ERP will absolutely make you uncomfortable — that’s the therapeutic mechanism. But it shouldn’t be traumatic. I pace exposures carefully, and you’re always in control of how far we go. You’re also in your own home, which many clients find more grounding than a clinical office.
“Will this work for my specific type of OCD?” Virtual ERP is effective across all OCD subtypes — contamination, checking, perfectionism, harm OCD, Pure O, symmetry, ROCD, and scrupulosity. The exposure hierarchy is customised to your specific presentation.
“What if my internet drops during an exposure?” It happens. We have phone backup protocols, and no single exposure is make-or-break. Technical glitches don’t derail treatment.
“I’ve tried therapy before and it didn’t work.” If your previous therapy focused on talking about your OCD without structured exposure work, that’s likely why. ERP is fundamentally different from insight-oriented therapy, and many of my clients see progress for the first time after switching approaches. If you’re unsure whether your previous experience counts, I’ve written more about finding the right OCD therapist and what to look for.

Frequently Asked Questions
How effective is virtual ERP compared to in-person?
Research consistently shows equivalent outcomes. The JMIR study of 3,500+ participants found virtual ERP produced a large effect size (g=1.0) — matching or exceeding many in-person benchmarks. Virtual ERP also achieved results in roughly half the total therapist time compared with standard outpatient treatment.
How long does ERP therapy take?
Most people see meaningful improvement within 12–20 sessions. The timeline depends on the severity and complexity of your OCD, whether there are co-occurring conditions like depression or anxiety, and how consistently you complete between-session exercises. I’ve written more about therapy timelines in general if you’re curious.
Can virtual ERP help with Pure O?
Yes. “Pure O” — OCD that presents primarily as mental obsessions and mental compulsions — responds well to ERP, particularly imaginal exposure techniques. The virtual format is equally effective for this subtype since the exposures are primarily cognitive rather than environmental.
Will I need medication alongside ERP?
Not necessarily. Many people respond well to ERP alone. For severe OCD or when progress plateaus, combining ERP with medication (typically SSRIs) can be helpful. I maintain a balanced perspective on this and can coordinate with your prescriber if medication becomes part of your plan.
What if my OCD gets worse before it gets better?
This is normal and expected in the early stages. When you stop performing compulsions, anxiety temporarily increases — that’s the therapeutic process working. Your brain needs to learn that the anxiety goes down on its own. This initial spike typically settles within the first few weeks, and most clients are already seeing net improvement by sessions 6–8.
Does insurance cover virtual ERP in Ontario?
