Start here, because it is the answer for most people reading this: if you already have video you're happy with, use a free standalone bilateral stimulation tool beside it — bilateralstimulation.io is the one most practitioners land on, and its basic tool needs no signup. It costs nothing, your client joins by clicking a link, and it works with whatever you're already running. There is no honest argument for paying for a second video platform to get stimulation you can have for free.

There are two situations where that stops being true. The first is the both- faces problem — a stimulation tool in a second window means somebody's face disappears, and on a phone it always does. The second is Canadian data residency, which matters to some practitioners and their Colleges more than to others, and which most of the free stimulation tools are not built around.

If neither of those applies to you, stop reading and go get the free tool.

What are the actual options?

Four shapes, and it's worth knowing which one you're shopping for.

Standalone stimulation tools. Single-purpose sites that deliver visual, auditory and sometimes tactile bilateral stimulation and are designed to sit alongside any video platform. bilateralstimulation.io is the widely used one; BilateralBase, remotEMDR and Virtual EMDR occupy the same space. Tactile generally means buying physical buzzers.

Practice-management platforms with video built in. Jane publishes that one-to-one video is included in every plan, with the connection running directly between the two devices rather than through their servers. Owl Practice publishes video therapy running on Canadian servers. If you're already paying for one of these, you already have your video.

Dedicated telehealth video. Purpose-built video for clinicians with no practice-management attached. Doxy.me is the best-known; its help documentation states that its servers are in the United States and that it does not store health information because calls connect directly between the two parties.

Platforms carrying video and stimulation together. The newest and smallest category — one session, one window, camera tiles preserved while the stimulus runs.

When is the free tool the right answer?

When all of these are true, which is most of the time:

• Your clients are on laptops or desktops, not phones.

• You are comfortable with the window arrangement, or you run audio-only sets.

• Your video platform already satisfies you and your College.

• You don't need the stimulation settings to live in a client record.

That is a large share of Canadian EMDR practice. The free tools are good, they are used by a very large number of EMDR therapists, and the people who built them built them for this exact problem. Paying for something else to avoid opening a second window is a poor trade.

When does the second window actually break?

Two places, and they are specific.

Phone-only clients. A phone shows one thing at a time. Either they see you or they see the stimulus. Every workaround here is worse than it sounds — a second device they may not have, or a set they run without seeing your face at all.

Screen-shared stimulation. If you run the tool on your machine and share your screen, many meeting platforms replace your camera with the shared content on the client's side. You keep looking at yourself and assume it's fine. Test it with a second device before you assume anything.

If neither of those describes your caseload, the window problem is a nuisance rather than a clinical cost.

What about Canadian data residency?

This is where the comparison genuinely changes for a Canadian practitioner, and it is also where the loudest claims are made. Treat "compliant" on any vendor page as marketing rather than as an answer, including the ones above.

The useful questions are narrower:

• What does the tool hold, and where? A stimulation tool that stores nothing is a very different risk surface from one holding client identifiers and session settings.

• Where does the video connection actually go? Several platforms connect the two devices directly and route through a server only when the network forces it.

• What does the vendor publish, in writing, that you could hand to a College reviewer? Not a badge — a document.

On the standalone stimulation tools specifically, the honest answer is that you usually cannot establish it at all. Read against their own published policies:

• bilateralstimulation.io says it processes data "primarily in the European Union and in the United States", and sells data residency as a line item on its top tier — which tells you the default is unspecified rather than Canadian.

• BilateralBase says it will not transfer data outside the UK or the European Economic Area "in a systematic way", then notes that its own hosting providers "may be based outside" it. Its pricing page separately claims compliance with Canadian privacy law; the policy behind that claim names no server location at all.

• remotEMDR names servers in the United States, and elsewhere in the same policy says it processes data "on our servers in different jurisdictions worldwide".

• Virtual EMDR names no country anywhere in its privacy policy, and it stores session content including distress ratings and worksheet entries.

None of the four names Canada. All four confirm in writing that they store something. In this category the question is usually unanswerable from the outside, which is itself the answer — a badge on a pricing page is not evidence of anything.

Whether that disqualifies a tool depends on your regulator, and at least one has put the requirement in writing. Nova Scotia's College of Counselling Therapists makes registrants responsible for

"ensuring that any and all electronic communication platforms used for telecounselling activities 1) are secure and compliant with the Personal Information Protection and Electronic Documents Act (PIPEDA), and 2) are hosted on servers housing data exclusively within Canadian jurisdiction."

— NSCCT, Interjurisdictional Telecounselling (Canada)

Read the scope of that before applying it to yourself. It sits inside a telecounselling policy and its subject is "electronic communication platforms used for telecounselling activities" — not every piece of software in a practice. Whether a stimulation tool running in a second window counts is a question for your own College, and if you are registered outside Nova Scotia it is your own regulator's published position that governs rather than this one.

Owl Practice publishes Canadian server residency for its video. Doxy.me publishes United States servers with the reasoning that it holds no health information. Those are two genuinely different answers to the same question, and which one satisfies you is a judgement about your own practice.

What about the clinical settings?

Worth checking regardless of which shape you pick.

• Is there a ceiling on the rate? Published EMDR protocols stay at or below two movements per second. A tool that will go faster is a tool you have to police yourself.

• Does anything advance between sets on its own? It shouldn't. The check-in between sets is the clinical work.

• Do the modalities stay together? A tone drifting behind the visual is invisible from your side of the screen.

• Is there a photosensitivity warning anywhere? Its absence tells you something about how the tool was built.

So what would you actually choose?

If you already pay for a practice-management platform with video: use its video, add a free stimulation tool, spend nothing more.

If your clients are largely on phones, or the both-faces problem is costing you something you can feel in sessions: that's the case for a platform carrying both, and it's a real case rather than a manufactured one.

If Canadian residency is a firm requirement from your College or your own posture: that narrows the video choice first, and the stimulation tool second.

And if you're a new EMDR practitioner with three virtual clients: free tool, whatever video you have, revisit in a year.
