Sleep studies in Ontario: what OHIP covers and how referral works

Last checked September 14, 2026. Coverage rules change — confirm with the official sources listed below.

In short

In Ontario, an in-lab sleep study (Level 1 polysomnography) is covered by OHIP when a physician orders it for a clinical reason, and is performed at hospital sleep labs or licensed independent health facilities. Home sleep apnea tests have historically been private-pay, though provincial reporting in 2026 describes OHIP-funded home testing being introduced. The Assistive Devices Program contributes toward CPAP costs for eligible residents.

Getting a sleep study in Ontario

  1. See your family doctor or a nurse practitioner. Bring notes on snoring, witnessed pauses, daytime sleepiness, and your STOP-Bang score.
  2. If a study is warranted, you are referred to a hospital sleep laboratory or a licensed independent sleep clinic. Many clinics accept referrals from any Ontario physician.
  3. The study is usually an overnight in-lab polysomnogram. Waiting times vary by region and clinic.
  4. A sleep physician interprets the results and discusses treatment options.

What OHIP covers

Level 1 (in-lab) polysomnography is conducted under the supervision of a sleep specialist at designated sleep clinics — some hospital-based, most run as independent health facilities under College of Physicians and Surgeons of Ontario standards — and is publicly funded through OHIP. Health Quality Ontario describes OHIP coverage of an initial diagnostic Level 1 study and repeat studies when clinically necessary.

Home sleep apnea tests have historically not been universally covered by OHIP and were often paid privately or through extended health benefits. Industry reporting in 2026 describes OHIP-funded at-home sleep apnea testing being introduced in Ontario; because this was in transition when this page was last checked, confirm current coverage with your physician or the Ministry of Health before assuming either way.

CPAP and device funding

Ontario’s Assistive Devices Program (ADP) contributes toward the cost of positive airway pressure devices for eligible Ontario residents with a confirmed diagnosis and a prescription, with the remainder paid by the resident or private insurance. Eligibility rules, the covered amount, and approved vendors are set out on ontario.ca.

How the city guides fit in

The referral and coverage rules above apply across the province; what differs by city is mainly the number of clinics, the waiting time, and the daylight. The Toronto and Ottawa guides cover those local details.

Each city guide adds what a national page cannot: the daylight your city actually gets across the year, its clock rules, the public sleep centres, and the local factors that shape sleep there.

Questions people ask

Is a sleep study covered by OHIP?

An in-lab polysomnogram ordered by a physician for a clinical reason is OHIP-insured at hospital sleep labs and licensed independent health facilities. Home sleep apnea tests have historically been private-pay in Ontario; provincial reporting in 2026 describes OHIP-funded home testing being introduced, so confirm current status with your physician.

Do I need a referral for a sleep clinic in Ontario?

For an OHIP-insured study, yes — a physician referral is required. Some private home-testing services operate without a referral, but their tests are not OHIP-covered.

Does OHIP pay for a CPAP machine?

Not directly. The Assistive Devices Program contributes toward the cost for eligible residents with a confirmed diagnosis and prescription; the balance is paid by the resident or private insurance.
