Sleep Studies in Canada: How It Works

In short

In Canada, sleep studies are ordered by a physician or nurse practitioner and paid for through provincial health plans when they are medically necessary. In-lab polysomnography is publicly insured in most provinces; coverage of home sleep apnea tests and of CPAP devices varies from province to province, which is why the details live on the province pages below.

The general path to a sleep study

Talk with a family doctor or nurse practitioner. They take a history, may use a screening tool such as STOP-Bang, and decide whether a sleep study is warranted.
Referral. The referral goes to a hospital sleep laboratory, a licensed or accredited private sleep clinic, or — in some provinces — an approved home-testing provider.
The study. Either an overnight in-lab polysomnogram (PSG) or a home sleep apnea test (HSAT), depending on the clinical picture and what is available locally.
Results and next steps. A sleep physician interprets the study; treatment options are discussed with you and your referring clinician.

What is publicly covered

Provincial and territorial plans generally insure in-lab polysomnography when a physician deems it medically necessary. Two things vary widely by province:

Home sleep apnea tests. Some provinces fund the professional fee for approved home-testing providers (British Columbia since 2022); in others, home tests have mostly been private-pay or covered by extended health benefits.
CPAP and other devices. Provincial device programs (for example Ontario’s Assistive Devices Program) may contribute toward the cost of positive airway pressure equipment for eligible residents; elsewhere, funding is limited to specific groups and most people rely on private insurance or pay directly.

National organisations and official sources

Canadian Sleep Society — the national professional body for sleep research and medicine, with public resources.
Canadian Thoracic Society — publishes Canadian guidance on sleep-disordered breathing.
Health Canada — regulates medical devices, including home sleep-testing equipment and CPAP machines, sold in Canada.

Guides by province

City guides in Canada

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

Do I need a referral for a sleep study in Canada?

In practice, yes. Publicly insured sleep studies are ordered by a physician or nurse practitioner. Privately paid home tests may have different rules, but results still need a clinician’s interpretation to be useful.

Is CPAP free in Canada?

Not generally. Some provinces contribute toward the cost through device programs for eligible residents; others fund devices only for specific groups. Private extended-health plans often cover part of the cost.
