One business day is the norm most practitioners describe when they say it out loud. Some say twenty-four hours, some say forty-eight, and almost nobody in private practice claims same-hour.
But the number is the less interesting half of the answer. What separates a callback that lands well from one that lands badly is not the elapsed time — it is whether the person knew what to expect while they waited. A caller who was told "I return calls within two business days" and hears from you on day two has had a good experience. A caller who was told nothing and hears from you the next morning has spent a night wondering whether you exist.
So the practical version is: pick a window you can hit on your worst week, say it out loud in your greeting and on your website, and make sure something reaches the caller straight away — even if that something is a recorded sentence or a short text rather than you.
That last part is what makes a slow window survivable. It is much easier to defend two business days when nobody has been sitting in silence for two business days.

Why the delay happens in the first place
It is worth naming, because therapists tend to describe this as a personal failing and it is mostly a structural one.
You cannot answer in session. The gaps between sessions go to notes, or to the bathroom, or to eating something. By the time the day is actually clear it is often past the hour when calling a stranger reads as professional. One practitioner put it plainly: the trouble is that when the work day is done, it is too late to look professional and call back.
That is not disorganisation. It is a day with no window in it. Any plan that depends on you finding fifteen quiet minutes between clients is a plan that will fail in a busy week, which is exactly the week it matters.
What does your College say about response times?
Less than most people assume, and the shape of what they do say is more useful than a number would be.
No Ontario regulator sets one. Searching the published standards of all three turns up no hour figure and no day figure. The strongest published sentence belongs to the social work College, which says registrants "shall deliver client services and respond to client queries, concerns, and/or complaints in a timely and reasonable manner" (OCSWSSW, Interpretation 3.4). That is the whole requirement. The psychotherapy College's only timeframe clause is about incoming referrals, not client contact. The psychology and behaviour analysis College publishes nothing on reachability at all.
What it asks instead is that you say what your own window is. The psychotherapy College's electronic practice guidance lists what a practitioner should cover with a client at the outset, and one item is "the therapist's usual hours of work and average response times to between-session communications from clients" (CRPO Electronic Practice Guideline). You set the number. You tell the client. The College is interested in whether you did that, not in what the number was.
That is better news than a fixed window, and it inverts the anxiety. A practitioner who returns calls in two days and told every client so at intake is in a stronger position than one who usually manages four hours, has never written it down, and misses a week in August.
What makes a slow callback feel bad
Three things, and none of them is the clock.
Silence. The caller cannot tell the difference between "she is with a client" and "this practice is not operating". Both look identical from outside.
Surprise. A window you never stated cannot be met or missed, so every delay reads as a delay.
Ambiguity about what happens next. "I'll call you back" is weaker than "I return calls Tuesday to Thursday afternoons." The second one lets somebody put their phone down.
What people actually do
Say the window in the greeting. The most common version names a range, says what to do if it is urgent, and points to another way in — an email address or a booking link. It costs nothing and it does most of the work.
Answer immediately without answering personally. A message that reaches the caller within a minute of the missed call changes the whole experience of waiting. Therapists have been building this by hand for years: notice the missed call, send a short intro text. One described the effect as emotionally easy, which is a fair summary of why it caught on.
Batch the callbacks. Pick two fixed slots a week, put them in the calendar as if they were sessions, and stop trying to squeeze calls into gaps. Slower on paper, more reliable in practice.
Move first contact off the phone entirely. Plenty of practitioners direct inquiries to a form or a booking page and never do a first call at all. This is a real option, not a fallback, and it removes the response-time question rather than answering it. It also loses you the people who will only ever use a phone.
Is faster always better?
No, and it is worth saying so, because there is a version of this advice that turns a practice into a switchboard.
A very fast response sets an expectation. If you answer new inquiries within the hour, some of the people who become clients will assume that is your speed forever, and the expectation is much harder to walk back than it was to set. Several practitioners describe deliberately being slower than they could be, for exactly this reason.
There is also a group of therapists who treat non-response as a legitimate filter, on the grounds that someone who cannot leave a voicemail is not ready to begin. That view has real support among clinicians. It has an obvious cost too — it filters on the wrong variable, and the people it screens out are disproportionately the ones for whom phone calls are hard.
The short version
Choose the window you can hit in a bad week, not a good one. Say it in the greeting and on the website. Make sure something reaches the caller immediately so nobody is left in silence while your window runs. Then hold the window rather than beating it, because the speed you show a new caller is the speed they will expect from you a year from now.
