Prescription Drug Coverage — Ontario
Sourced from Canadian federal statutes and official sources. Provincial information reflects each province's own legislation and court rulings. Written in plain language for general understanding — this is educational content, not legal advice. Our editorial standards
What is this right?
This is the famous gap. The Canada Health Act covers drugs given in hospital, but the moment you fill a script at the pharmacy, that universal-coverage promise stops. What you get instead is a patchwork of provincial plans, federal programs, and private insurance.
Every province runs a public drug plan, but eligibility varies wildly. Most cover seniors and social assistance recipients, and several catastrophic-coverage programs help people whose drug costs are large relative to income.
The federal programs that fill specific gaps:
- NIHB — Non-Insured Health Benefits for First Nations and Inuit
- Veterans Affairs coverage
- IFHP — Interim Federal Health Program for refugees
- Coverage for federal inmates
The big recent shift is the Pharmacare Act (2024), which launched phase 1 of national pharmacare covering contraceptives and diabetes medications. The rollout runs through 2025-2026 via bilateral agreements with the provinces. About two-thirds of Canadians still have employer-sponsored drug coverage doing most of the work.
When does it apply?
- Eligibility depends on the program — provincial plans cover defined groups, and national pharmacare phase 1 is rolling out gradually.
- About two-thirds of Canadians have some form of employer-provided coverage on top.
What to Do If You Can't Afford Prescription Drugs in Canada
- Check provincial eligibility. Most uncovered Canadians qualify for something they've never enrolled in.
- Apply to your province's program — Trillium in Ontario, Fair PharmaCare in BC, or the equivalent.
- Ask your pharmacist about national pharmacare for diabetes medications and contraceptives — the rollout is uneven and pharmacies are the practical front line.
- Register for NIHB if you're First Nations or Inuit.
- Keep every pharmacy receipt. The medical expense tax credit can claw back a meaningful share at tax time.
What should you NOT do?
- Don't assume you have no coverage. The single biggest reason Canadians miss benefits is that they never applied.
- Don't skip medications because of cost. Pharmacists can flag generic equivalents and patient-assistance programs.
- Don't conflate hospital and outpatient coverage. Same drug, two pricing realities depending on where it's dispensed.
- Don't overlook the medical expense tax credit. It is the federal lever most people forget exists.
How Ontario differs from federal law
OHIP does not cover prescription drugs at the pharmacy, but Ontario has several provincial programs that provide drug coverage to specific populations.
- The Ontario Drug Benefit (ODB) Program provides prescription drug coverage to: seniors aged 65 and over, people receiving Ontario Works (social assistance) or Ontario Disability Support Program (ODSP) benefits, residents of long-term care homes and certain home care recipients, and people with high drug costs relative to income through the Trillium Drug Program.
- OHIP+ provides free coverage of approximately 5,000 prescription drug products to children and youth aged 0 to 24 who do not have private insurance. If you have private insurance, OHIP+ does not apply and your private plan pays first.
- The Trillium Drug Program helps Ontario residents with high prescription drug costs. If your drug costs are roughly 4% or more of your net household income and you don't qualify for ODB, you may qualify for Trillium. You pay a deductible based on income.
- Seniors on ODB pay a co-payment of up to $6.11 per prescription (or $2.00 per prescription if your income is below approximately $22,200 for single, $37,100 for couples and you apply for the Seniors Co-Payment Program).
- The ODB Formulary lists all drugs covered by Ontario's public drug programs. Not every drug is on the Formulary — if your drug is not listed, your doctor can request Exceptional Access.
Additional Steps in Ontario
Seniors are automatically enrolled in ODB when they turn 65 — bring your OHIP card to the pharmacy. For OHIP+ (children and youth), no application is needed if you don't have private insurance. For the Trillium Drug Program, apply online at ontario.ca/page/get-help-high-prescription-drug-costs or call 1-800-575-5386. If your drug is not on the Formulary, ask your doctor to submit an Exceptional Access Program (EAP) request to the Ministry of Health.
Relevant Law: Ontario Drug Benefit Act, R.S.O. 1990, c. O.10; O. Reg. 201/96 (General Regulation under ODB Act); Ontario Regulation 201/96, as amended (OHIP+)
