By Jatin Dua · Broker of Record, RE/MAX Quantum Realty · Updated 18 October 2026 · 9 min read — how to judge sound privacy, what CRPO and PHIPA expect for records, office versus medical office zoning, shared and sublet rooms, and the lease clauses to negotiate.

Short answer

A psychotherapy office in Ontario needs sound privacy between rooms and to the waiting area, a waiting space that protects client identity, lockable storage that only the custodian controls, and evening access. CRPO's Professional Practice Standards (revised December 2025) expect records and devices to be locked away, screens kept out of view and clinical records kept at least 10 years. PHIPA requires reasonable steps to protect health information. Zoning may treat the practice as office or medical office, which affects where you can locate and, in Mississauga, the parking rate. Shared rooms need written records arrangements and head landlord consent.

What a psychotherapy office actually needs

A psychotherapy practice needs very little equipment and a lot of privacy. Clients need to arrive without being seen by half the plaza, talk without being overheard, and leave knowing their file is locked away. The building decisions that matter are walls, doors, ducts, sightlines and storage, not plumbing or power.

Sound privacy between rooms and to the waiting area. Nothing in the provincial rules gives you a number to rely on, so you set the standard yourself in the lease and work letter.
A waiting area that protects identity: not visible from the corridor or storefront, and ideally laid out so people leaving a session do not walk past those arriving.
Lockable storage for paper records and devices, and screens positioned so they cannot be read from the doorway.
A barrier-free route and washroom where the fit-out is extensive, and a washroom that does not require clients to cross a public lobby if you can avoid it.
Evening and weekend access, since many clients come after work.

What CRPO and PHIPA expect from the premises

Registered psychotherapists are governed by the College of Registered Psychotherapists of Ontario. Its Professional Practice Standards took effect January 1, 2024, and were most recently revised December 11, 2025. Several standards translate directly into space decisions:

Confidentiality (Standard 3.1). In compliance with PHIPA, registrants must keep the professional relationship and client information confidential and maintain client information securely so unauthorized people cannot access records.
Physical safeguards (Standard 5.6). The College lists examples: securing paper records and electronic devices in locked spaces, ensuring screens showing health information cannot be viewed by unauthorized people, and securely disposing of paper files, for example with micro-cut shredding.
Retention (Standards 5.1, 5.4 and 5.5). Where the registrant is custodian, clinical records are kept at least 10 years from the last interaction, or 10 years from the client’s 18th birthday, whichever is later. Appointment and financial records are kept at least ten years from the last interaction.
Shared practices (Standard 5.1). In a shared or group practice, the College says to clarify in writing at the outset who owns the records: the registrant, a clinical supervisor or the group practice.

The Personal Health Information Protection Act, 2004 sits underneath all of this. Section 12(1) requires a health information custodian to take steps that are reasonable in the circumstances to protect personal health information against theft, loss and unauthorized use or disclosure. Section 13(1) requires records to be retained, transferred and disposed of in a secure manner. A storage room the landlord’s cleaners can open at night is not a reasonable step.

Your records outlive your lease

A five-year lease does not end your ten-year retention duty. Before you sign, decide where records will live if you move or close, and make sure the lease lets you remove them, and that the landlord has no right to hold or access them.

Zoning: office or medical office?

Most psychotherapy practices fit in ordinary office space, but how the city classifies the use still matters.

Toronto. By-law 569-2013 lists “office” and “medical office” as uses but does not define either in Chapter 800. It does define a “wellness centre” as premises providing services for therapeutic and wellness purposes, and says a medical office is not a wellness centre. Office, medical office and wellness centre are all permitted in the CR zone. The difference shows up elsewhere: the EL and E employment zones permit office but do not list medical office. If you are looking at a low-cost unit in an employment area, ask the zoning examiner in writing which category your practice falls under. Parking is also tiered differently, with office in Tier 2 and medical office in Tier 4, though both are now maximums rather than minimums.

Mississauga. By-law 0225-2007 defines Medical Office as space used for consultation, examination or therapeutic treatment by a physician, dentist, drugless practitioner or health professional licensed by the Province, and also has a narrower “Medical Office – Restricted.” The parking difference is real: office requires 2.0 to 3.0 spaces per 100 square metres depending on the precinct, while medical office requires 3.8 to 5.5. In an office building, where non-office uses including medical office exceed 10 per cent of the building’s gross floor area, separate parking is required for those uses. That can make a landlord hesitant to sign another health tenant, so raise it early.

Brampton, Vaughan, Markham and Oakville each have their own definitions; confirm with the city where the unit is.

Shared offices, sublets and room rentals

Many therapists start by renting a room by the day or half-day in someone else’s suite. That can work well, but it moves several obligations onto paper:

The head lease must allow it. Most leases restrict subletting and licensing without landlord consent. If the suite holder has not obtained consent, your room can disappear with little notice.
Records custody. Agree in writing who is the health information custodian for your clients and where files are stored, as CRPO Standard 5.1 recommends for shared practices.
Your own locked storage. A shared filing cabinet does not meet the “locked spaces” safeguard if other practitioners have the key.
Market rent. CRPO Standard 1.6 on conflict of interest says registrants are expected to pay for premises and equipment at a reasonable, market rate. Taking a free or cheap office from someone who could benefit from your referrals creates at least the appearance that you will favour them.
Controlled act and title. Psychotherapy that treats a serious disorder of thought, cognition, mood, emotional regulation, perception or memory is a controlled act under the Regulated Health Professions Act, 1991. If you are the suite holder, check that the people you license rooms to are authorized for what they do.

If you are considering a coworking space instead, look closely at who can enter the rooms after hours and whether you can install your own lockable storage.

Building permit and accessibility

Moving a psychotherapy practice into existing office space usually does not change the building’s use. If the unit was retail or something else, section 10 of the Building Code Act, 1992 requires a permit where a change of use increases the hazard, even without construction, so ask your designer before you assume. New walls, doors and ductwork changes for sound privacy normally need a building permit in any case.

Ontario’s Building Code accessibility requirements apply to most new construction and extensive renovations, including barrier-free washrooms in public areas. For a small office suite, the practical test is whether a client using a wheelchair can get from the parking lot to your door and into a washroom without help.

T-bar walls are the most common failure

Many office suites are divided by partitions that stop at the suspended ceiling. Speech travels over the top through the ceiling space and through shared return-air grilles. Lift a ceiling tile on the viewing. If the wall stops there, budget for extending it to the deck and insulating it, and get the landlord to agree in the lease.

The lease clauses that matter for a psychotherapy practice

Use clause. “Psychotherapy, counselling and mental health services, including individual, couple, family and group sessions, provided by regulated health professionals, and related administration.” Broad enough for group work and associates.
Sublicensing. The right to license rooms to other regulated health professionals without separate consent each time.
Sound work. Landlord’s work or allowance to extend demising walls to the deck, insulate them, fit solid-core doors with seals and treat duct paths.
Neighbour restrictions. No high-noise uses on the other side of your walls.
Landlord entry. Entry on notice except in emergencies, and no right for the landlord or its contractors to open locked records storage.
Records at the end of term. Express confirmation that client records are not part of any property the landlord may hold for unpaid rent, and the right to remove them at any time.
Hours and HVAC. Evening and weekend access with HVAC included, not billed as after-hours overtime.
Signage. The right to keep signage discreet, since many clients prefer it.
Assignment. Assignment to a professional corporation or a buyer of the practice.

Office rent is quoted as net rent per square foot per year plus additional rent for taxes, maintenance and insurance, or as a gross rent in smaller office buildings. If you are deciding whether to buy a small office condo instead, the office space value estimator gives a first read. My notes on the use clause cover the wording in more depth.

Closing or moving the practice

CRPO Standard 6.4 covers closing or relocating a practice. Registrants planning to close or relocate take reasonable steps to give appropriate notice to each client they have primary responsibility for, with an expected minimum of 30 days for a foreseeable closure. They must have a contingency plan for unexpected interruptions, and custodians must keep the College informed about who would take custody of records if they died or could not continue. Records stay secure for the full retention period even after the practice closes, unless they are transferred to another custodian.

For the lease, that means your renewal, termination and relocation clauses need enough notice built in for you to meet those obligations. A landlord relocation clause with 60 days’ notice is a problem if it forces a rushed move of client records and appointments.

Deal-killers to check on a viewing

Partitions that stop at the ceiling grid and a shared return-air plenum.
A waiting area visible from the plaza or a busy common corridor.
Washrooms only reachable through a public lobby or another tenant’s space.
No evening access or HVAC that shuts off at 6 p.m.
A noisy neighbour: a gym, a dance studio or a restaurant kitchen against your therapy room wall.
A shared suite with no consent from the head landlord to sublet or license rooms.
No lockable storage that only you control.

Practitioners in neighbouring fields face similar issues; see my notes on massage therapy clinic space.

Where I fit

I help psychotherapists and group practices find and assess office space across Toronto, Mississauga, Brampton and the rest of the GTA. Before you sign, I check how the city will classify the use, lift the ceiling tiles with you to see where the walls stop, and read the lease for sublet rights, landlord entry and what happens to your records if the lease ends early.

I will come back to you personally, usually the same day, with spaces that fit. If it is urgent, call or text 833-330-1925.

Frequently asked questions

What does CRPO require for storing client records in my office?

CRPO's Professional Practice Standards list physical safeguards such as securing paper records and electronic devices in locked spaces, keeping screens that show health information out of view of unauthorized people, and securely disposing of paper files, for example by micro-cut shredding. PHIPA separately requires custodians to take reasonable steps to protect personal health information against theft, loss and unauthorized access.

How long must a psychotherapist keep client records in Ontario?

Under CRPO's standards, where the registrant is the custodian, clinical records are kept at least 10 years from the last interaction with the client or 10 years from the client's 18th birthday, whichever is later. Appointment and financial records are kept at least ten years from the last interaction. Plan storage that outlasts your lease.

Is a psychotherapy practice zoned as office or medical office?

It depends on the city. Toronto's by-law lists both office and medical office without defining them, and some employment zones permit office but not medical office. Mississauga defines medical office around licensed health professionals and applies higher parking rates to it. Ask the zoning examiner for a written answer for your specific address and practice.

Can I rent a therapy room by the day in another practitioner's office?

Yes, if the head lease allows sublets or room licences and the suite holder has the landlord's consent. Agree in writing who is the health information custodian and where your records are stored, as CRPO recommends for shared practices, and pay a market rate, since CRPO's conflict of interest standard warns against free or low-cost space from someone who benefits from your referrals.

How do I check sound privacy when viewing an office?

Lift a ceiling tile to see whether the demising walls stop at the suspended ceiling or continue to the deck. Look for shared return-air grilles between rooms and check whether doors are solid core. Have someone talk at normal volume in one room while you listen from the next room and the waiting area. Put any fixes in the lease or work letter.

What lease clauses matter most for a therapist?

A broad use clause covering individual and group therapy, the right to license rooms to other regulated professionals, landlord-funded sound work, limits on noisy neighbours, entry on notice with no access to locked records, the right to remove records at any time, evening access with HVAC included, discreet signage and assignment to a professional corporation.

What notice do I need to give clients if I move my practice?

CRPO Standard 6.4 expects registrants who close or relocate to take reasonable steps to notify each client they are primarily responsible for, with a minimum of 30 days for a foreseeable closure. Make sure your lease renewal, termination and any landlord relocation clause leave enough time to meet that and move records securely.
