Inspire Sleep and Hypoglossal Nerve Stimulation in Canada: What You Need to Know
Inspire sleep therapy in Canada has become an increasingly searched alternative for people with obstructive sleep apnea who struggle with CPAP. However, it comes with specific eligibility criteria and important considerations worth understanding before exploring it as an option. This guide explains how it works, who qualifies, and how it compares to CPAP therapy.
What Is Inspire Sleep Therapy?
Inspire is a brand of upper airway stimulation device developed to treat obstructive sleep apnea in patients who cannot tolerate CPAP therapy. It is a surgically implanted device that delivers mild electrical stimulation to the hypoglossal nerve, which controls the movement of the tongue and surrounding airway muscles. This stimulation keeps the airway open during sleep.
The device consists of three components implanted under the skin: a small generator placed in the chest, a breathing sensor that monitors respiratory effort, and a stimulation lead that connects to the hypoglossal nerve. The patient activates it each night with a small handheld remote before falling asleep. Additionally, the device works in sync with the patient’s natural breathing pattern throughout the night.
Inspire received FDA approval in the United States in 2014 and has been available to Canadian patients through select surgical centres. However, access and coverage vary by province. Ontario patients interested in Inspire sleep therapy in Canada should begin by speaking with a sleep specialist or otolaryngologist (ear, nose and throat surgeon).
What Is Hypoglossal Nerve Stimulation?
Hypoglossal nerve stimulation (HNS) is the broader category of treatment that Inspire belongs to. The hypoglossal nerve is responsible for tongue movement. In obstructive sleep apnea, the tongue and soft tissues fall backward during sleep, blocking the airway. HNS devices prevent this by delivering a gentle electrical pulse that keeps the tongue forward and the airway open.
In addition to Inspire, other HNS devices are in various stages of development and approval. The principle is the same across all of them: a surgically implanted system that responds to breathing signals and stimulates the airway muscles accordingly.
Because HNS is a surgical intervention, it requires a referral to a specialist and a thorough evaluation of surgical candidacy. It is not a first line treatment for sleep apnea in Canada. Therefore, most patients explore it only after CPAP therapy has been attempted and found to be unworkable for their situation.
Who Qualifies for Inspire Sleep Therapy in Canada?
Eligibility criteria for Inspire sleep therapy in Canada are specific and not everyone with sleep apnea qualifies. In general, candidates must meet all of the following criteria:
- A confirmed diagnosis of moderate to severe obstructive sleep apnea, typically with an AHI between 15 and 65 events per hour
- Have tried CPAP therapy and found it to be unsuitable or not tolerated despite genuine attempts
- A body mass index (BMI) below a threshold set by the treating surgical centre (commonly below 32 to 35)
- No complete concentric collapse of the palate, assessed by a drug induced sleep endoscopy procedure
- Be 18 years of age or older
The eligibility assessment process involves a sleep study review, a consultation with an otolaryngologist or sleep surgeon, and in most cases a drug induced sleep endoscopy (DISE) to assess airway anatomy under sedation. Not every patient who applies will meet all criteria.
Inspire Sleep vs. CPAP Therapy: How They Compare
CPAP therapy remains the most widely prescribed and evidence supported treatment for obstructive sleep apnea in Canada. It is non invasive, adjustable, reversible, and has decades of clinical evidence behind it. For the vast majority of patients, CPAP is the recommended first line treatment.
However, a meaningful proportion of patients find CPAP therapy difficult to tolerate long term. Common challenges include mask discomfort, claustrophobia, air pressure sensitivity, and difficulty sleeping with equipment on the face. For these patients, HNS offers a surgical alternative that removes the nightly mask requirement.
| Feature | CPAP Therapy | Inspire / HNS |
|---|---|---|
| How it works | Pressurized air keeps airway open | Electrical stimulation keeps airway open |
| Invasiveness | Non invasive (mask and machine) | Surgical implant required |
| Reversibility | Fully reversible, stop anytime | Device can be removed but surgery required |
| Who it suits | Most OSA patients | Selected patients who cannot tolerate CPAP |
| Availability in Canada | Widely available | Select surgical centres |
| Cost and coverage | ADP and insurance partial coverage | Limited coverage, high out of pocket cost |
Is Inspire Sleep Available in Ontario?
Yes, Inspire sleep therapy in Canada is available in Ontario through select academic hospitals and surgical centres. However, it is not widely available at community clinics and wait times for assessment and surgery can be significant. Additionally, the cost of the procedure is high and provincial coverage is limited, meaning many Ontario patients face substantial out of pocket expenses.
For most Ontario patients presenting with obstructive sleep apnea, the pathway begins with CPAP therapy. A dedicated sleep clinic like Ontario Sleep Care can diagnose sleep apnea, start CPAP treatment, and provide ongoing support. If CPAP proves genuinely unworkable after a reasonable trial period, your Sleep Clinician can discuss a referral to a specialist for HNS assessment.

Frequently Asked Questions
Is Inspire sleep therapy available in Canada?
Yes. Inspire sleep therapy is available in Canada through select surgical centres, primarily in major academic hospitals. It is not as widely available as CPAP therapy and is typically accessed after CPAP has been attempted and not tolerated. Speak with your sleep specialist or ENT surgeon about access in your area.
Does OHIP cover Inspire sleep therapy in Ontario?
Coverage for Inspire therapy in Ontario is limited. As of 2026, it is not routinely covered by OHIP, and the out of pocket cost is significant. Coverage may be available in specific circumstances. Speak with the surgical centre performing the assessment for the most current information on costs and coverage.
What is the difference between Inspire and CPAP?
CPAP is a non invasive therapy that uses pressurized air through a mask to keep the airway open during sleep. Inspire is a surgically implanted device that uses electrical stimulation of the hypoglossal nerve to achieve the same result. CPAP is the first line treatment for most patients. Inspire is reserved for patients who cannot tolerate CPAP after a genuine attempt.
How do I know if I qualify for hypoglossal nerve stimulation in Canada?
Eligibility requires a confirmed moderate to severe sleep apnea diagnosis, documented CPAP intolerance, a BMI within the accepted range, and suitable airway anatomy confirmed by drug induced sleep endoscopy. A sleep specialist or otolaryngologist performs the full assessment.
Can CPAP therapy work if I have failed it before?
Yes, in many cases. Many people who have struggled with CPAP in the past did so because of poor mask fit, incorrect pressure settings, or lack of proper clinical support. With the right equipment, professional fitting, and follow up from a Sleep Clinician, many patients who previously gave up on CPAP find therapy manageable.
