Mental Health Treatment Denied in Canada: Appeal

Canada's universal health care system covers physician-delivered mental health services, but it does not cover most psychotherapy, counselling, or psychiatric medications — leaving millions of Canadians reliant on employer group benefit plans, individual private insurance, or out-of-pocket payments. When those plans deny claims, the consequences can be severe. Here is how to navigate a mental health insurance denial in Canada.

How Mental Health Coverage Works in Canada

Provincial public plans: Provincial health insurance (e.g., OHIP in Ontario, MSP in BC, AHCIP in Alberta) covers visits to psychiatrists — who are physicians — at no direct cost to the patient. However, visits to psychologists, registered social workers, and other regulated mental health professionals are not covered by most provincial plans. A few provinces are gradually introducing publicly funded psychotherapy, but coverage remains limited.

Employer group benefit plans: The majority of working Canadians access psychological therapy through employer-sponsored extended health benefit plans. These plans typically offer a dollar cap — often $500 to $2,000 per year — for psychological services, which is frequently insufficient for conditions like PTSD, OCD, eating disorders, or treatment-resistant depression.

Individual private plans: Purchased independently, these plans vary widely in the mental health benefits they include. Pre-existing condition exclusions and waiting periods are common barriers.

Common Reasons Mental Health Claims Are Denied

• Provider not a covered category: Plans may only cover registered psychologists and exclude registered social workers, counsellors, or therapists — even if they are regulated health professionals in your province.
• Annual dollar limit exhausted: Once the plan's annual mental health maximum is reached, claims are automatically denied.
• Treatment deemed not medically necessary: Insurers may require a physician's referral or clinical documentation of diagnosis before authorising psychological services.
• Residential or intensive outpatient program excluded: Inpatient or intensive mental health programs are often excluded from standard extended health benefit plans.
• Pre-existing condition exclusion: Some plans exclude any mental health condition that was present — or that you received treatment for — before coverage began.

How to Appeal a Mental Health Denial in Canada

Step 1 — Internal appeal with your insurer: Request the denial in writing, including the specific policy clause relied upon. Respond with a letter from your treating psychologist or psychiatrist explaining the medical necessity of treatment, any clinical guidelines supporting the approach (e.g., Canadian Psychological Association guidelines), and the consequences of not receiving care.

Step 2 — Employer HR or union grievance: If your denial comes from a group benefits plan, your HR department or union may have leverage to assist. Group benefit plans are administered by the insurer but the policy is held by your employer — employers can sometimes advocate for individual employees or negotiate exceptions.

Step 3 — OmbudService for Life and Health Insurance (OLHI): OLHI is a free, independent service that reviews disputes between individuals and their life and health insurance companies. It covers group and individual plans. You must complete the insurer's internal complaint process first. OLHI can recommend — but not legally compel — an insurer to overturn a decision, though most insurers comply.

Step 4 — Provincial Insurance Regulator: The Financial Services Regulatory Authority of Ontario (FSRA), BC Financial Services Authority (BCFSA), or your provincial equivalent can investigate complaints about insurer conduct — particularly if you believe the denial was made in bad faith or the insurer failed to fairly investigate your claim.

Step 5 — Provincial Ombudsman: For complaints about provincially funded mental health services — such as a public inpatient psychiatric unit — your provincial Ombudsman investigates government-run health services.
