TL;DR: An accredited hyperbaric oxygen therapy (HBOT) clinic in Canada is a facility that meets recognised safety standards, uses a Health Canada licensed chamber, and operates under qualified medical supervision. To find one, verify the chamber type, check for UHMS or CSA-aligned safety practices, confirm physician oversight, ask about staff training, and request a referral pathway. Canada Hyperbarics maintains a directory of hospitals and regulated facilities to help patients begin this search.
Choosing where to receive hyperbaric oxygen therapy is one of the most important decisions a patient will make about their treatment. An accredited hyperbaric oxygen therapy clinic is a healthcare facility that uses a Health Canada licensed pressure chamber, follows recognised safety standards from bodies such as the Undersea and Hyperbaric Medical Society (UHMS), and provides treatment under qualified medical supervision. In Canada, accreditation is not delivered by a single national body, so patients must look at several practical signals to confirm a clinic is safe, regulated, and clinically appropriate.
This step-by-step guide walks Canadian patients through how to find an accredited hyperbaric oxygen therapy clinic, what questions to ask, which credentials matter, and how to use the Canada Hyperbarics directory of hospitals and regulated facilities as a starting point.
What does accreditation mean for a hyperbaric clinic in Canada?
Accreditation is a formal recognition that a clinic meets defined safety, equipment, and clinical standards. In Canadian hyperbaric medicine, accreditation usually combines three layers:
- Health Canada licensing of the pressure chamber. Every chamber used to treat patients must be a Class III medical device licensed under the Medical Devices Regulations.
- Provincial health facility regulation. Hospitals operate under their provincial health authority. Private clinics are regulated by the provincial ministry of health and, depending on the province, the College of Physicians and Surgeons.
- Voluntary professional accreditation. Many clinics align with safety and clinical standards from the UHMS, the Canadian Undersea and Hyperbaric Medical Association (CUHMA), and CSA Group standard Z275 for hyperbaric facilities.
According to a 2025 systematic review of non-pharmacological wound care interventions including HBOT, safety profiles vary significantly by setting and protocol, which underscores why facility-level accreditation matters for patient outcomes (Gong et al., 2025, DOI: 10.1186/s12912-025-04065-x).
How do you confirm a chamber is Health Canada licensed?
The first thing to check is whether the chamber itself is a Health Canada licensed medical device. Medical-grade hyperbaric chambers are pressurized to at least 1.4 atmospheres absolute (ATA) using 100 percent oxygen and are classified as Class III devices. Soft-shell mild hyperbaric chambers (often 1.3 ATA with ambient air) are not equivalent and are not used for the approved clinical indications listed by the UHMS.
Ask the clinic directly: Is the chamber Health Canada licensed, and what is its medical device licence number? A regulated facility will provide this information. You can verify a licence on the Health Canada Medical Devices Active Licence Listing (MDALL) database.
Comparison: Medical-grade vs. mild hyperbaric chambers
| Feature | Medical-grade HBOT | Mild HBOT (mHBOT) |
|---|---|---|
| Pressure | 1.4 to 3.0 ATA | 1.3 ATA |
| Oxygen concentration | 100 percent | Ambient air (21 percent) |
| Health Canada class | Class III | Not licensed by Health Canada |
| Used for recognised conditions | Yes | No |
| Typical setting | Hospitals and regulated clinics | Wellness or home use |
How do you verify physician oversight and clinical staffing?
An accredited HBOT clinic operates under the supervision of a physician with hyperbaric training, ideally one who is a member of CUHMA, holds UHMS certification, or has completed an Advanced Training in Diving and Hyperbaric Medicine course. The clinic should also employ certified hyperbaric technologists (CHTs) or trained chamber operators who follow CSA Z275-aligned operating procedures.
Ask the clinic these specific questions:
- Who is the medical director, and what is their hyperbaric medicine training?
- Is a physician on site or immediately available during every treatment?
- Are chamber operators certified hyperbaric technologists?
- What pre-treatment screening is performed?
- What emergency procedures are in place for complications such as oxygen toxicity, barotrauma, or fire safety events?
Pre-treatment medical screening is critical. A 2021 prospective study at the Amsterdam University Medical Centre on HBOT for Crohn disease found that even in a controlled hospital setting, treatment-related adverse events including claustrophobia and fatigue can occur, which is why physician screening matters before every protocol (Lansdorp et al., 2021, DOI: 10.1093/bjsopen/zrab042).
How do you confirm a clinic treats recognised conditions?
The Undersea and Hyperbaric Medical Society publishes the internationally recognised list of recognised indications for HBOT. A regulated Canadian clinic will treat conditions on this list, which includes wound healing in diabetic foot ulcers, radiation injury, carbon monoxide poisoning, decompression sickness, sudden sensorineural hearing loss, osteomyelitis, and several others. You can review these in the Canada Hyperbarics conditions library.
Be cautious of any clinic that markets HBOT as a treatment for conditions not supported by the published evidence base. Health Canada advertising guidelines prohibit unsupported therapeutic claims, and a clinic that markets responsibly is a strong signal of a regulated operation. A 2024 systematic review and network meta-analysis of insomnia and adjacent indications similarly noted that hyperbaric oxygen therapy carries a favourable safety profile when delivered in monitored clinical environments, with most reported adverse events being minor and transient (Wang et al., 2024, DOI: 10.3389/fneur.2024.1297767).
What should you ask about referral and coverage pathways?
An accredited clinic will have a clear referral pathway. In most provinces, hospital-based HBOT for recognised indications is covered by the provincial health insurance plan when ordered by a physician. Coverage by name:
- Ontario: OHIP covers hospital HBOT for recognised indications.
- British Columbia: MSP covers hospital-based HBOT.
- Alberta: AHCIP covers hospital-based HBOT.
- Quebec: RAMQ covers hospital-based HBOT.
- Manitoba: Manitoba Health covers hospital-based HBOT.
- Saskatchewan: Saskatchewan Health covers hospital-based HBOT.
- Nova Scotia: MSI covers hospital-based HBOT.
- New Brunswick: Medicare NB covers hospital-based HBOT.
- Newfoundland and Labrador: MCP covers hospital-based HBOT.
- PEI: PEI Health covers hospital-based HBOT.
Private clinic treatment for off-label or non-emergency indications is generally not covered. Ask the clinic about referral requirements, expected number of sessions, and out-of-pocket costs before committing.
How can the Canada Hyperbarics facility directory help?
Canada Hyperbarics maintains a verified directory of hospitals and regulated facilities across every province and territory. Each listing includes facility type (hospital or private), chamber type, contact information, and the conditions treated. The directory is updated monthly and serves as the most reliable starting point for patients trying to identify accredited HBOT options near them.
Use the directory together with this checklist to shortlist clinics, then call each one and run through the questions in Steps 1 and 2 above. Patients can also review summaries of the underlying clinical evidence on the Canada Hyperbarics research bank.
What are the warning signs of an unaccredited HBOT clinic?
Some patterns indicate a clinic is operating outside the regulated mainstream of Canadian hyperbaric medicine. Avoid clinics that:
- Cannot or will not provide their Health Canada medical device licence number.
- Market HBOT for cancer cure, anti-aging, or autism cure without disclosing that these are not recognised indications.
- Have no physician on site or no named medical director.
- Use only soft-shell or mild HBOT chambers but charge prices comparable to medical-grade treatment.
- Refuse to provide written information about their safety procedures.
- Do not perform medical screening before the first treatment.
Frequently asked questions about finding an accredited HBOT clinic
Is there a single Canadian accreditation body for hyperbaric clinics?
No. Canada does not have a single national accreditation body for hyperbaric medicine. Accreditation is layered: Health Canada licenses the chamber, the province regulates the facility, and professional bodies such as UHMS and CUHMA provide voluntary clinical standards.
Are hospital HBOT programs always safer than private clinics?
Hospital programs operate under provincial health authority oversight, which provides one consistent layer of regulation. Well-run private clinics with Health Canada licensed chambers and qualified medical directors can also meet a high standard. The key is verifying the credentials, not the setting alone.
What credentials should the medical director have?
The medical director should be a licensed physician in the province where the clinic operates and should have completed formal hyperbaric medicine training. Membership in CUHMA, UHMS certification, or completion of an accredited fellowship in undersea and hyperbaric medicine are positive credentials.
How do I report a clinic that is operating without proper accreditation?
Concerns about chamber safety can be reported to Health Canada through the Medical Devices Problem Report. Concerns about a physician practice can be reported to the provincial College of Physicians and Surgeons. Concerns about misleading advertising can be reported to Health Canada or the Competition Bureau.
Does the chamber type matter for clinical outcomes?
Yes. The published clinical evidence base for HBOT is built almost entirely on medical-grade chambers operating at 1.5 to 3.0 ATA with 100 percent oxygen. Mild HBOT systems do not deliver the physiological dose used in clinical trials and should not be substituted for medical-grade treatment when an evidence-based indication is present.
How many HBOT sessions should I expect to need?
Most approved protocols range from 20 to 60 sessions depending on the indication. Diabetic foot ulcer protocols typically run 30 to 40 sessions. Radiation injury protocols often require 30 to 60. The medical director will set the protocol based on your condition and response.
Will my family doctor refer me to an HBOT clinic?
Family physicians can refer to hyperbaric medicine the same way they refer to any specialty service. For recognised indications, hospital-based programs accept these referrals through standard provincial pathways. For private clinic treatment, a referral is often still requested even though the cost is out of pocket.
