The Trillium Drug Program (TDP)

What does the program cover?

The TDP helps people who have high prescription drug costs relative to their household income. It covers all drugs approved under the Ontario Drug Benefit (ODB) program. For drug products that are not on the list of approved ODB products, your doctor may apply for special approval through the Exceptional Access Program (EAP).

Who can apply?

You may qualify for the Trillium Drug Program if:


What costs will I pay?

Under the TDP, you will pay two different fees each year:

  1. You will pay a set amount of your prescription drug costs each year. This amount is called your "deductible." The amount of your deductible is based on your household income. For most people, the deductible equals about 4% of your household’s combined net income. Net income is the amount shown on line 236 of your Notice of Assessment issued under the Income Tax Act (Canada) minus the amount of income from the Universal Child Care Benefit program (reported on line 117 of your tax return) and the amount withdrawn from your Canadian Registered Disability Savings Plan (reported on line 125 of your tax return).

    The deductible you have to pay is split into four equal amounts over the year starting on August 1st.  You pay your deductible by purchasing ODB approved prescription drug products at your pharmacy.  Once you have purchased enough of these products to equal the amount of your deductible, then the ODB program pays for most of the cost of your drugs.

  2. After you pay your deductible, you pharmacist may ask you to pay up to $2 for each prescription that the ODB program covers.  This amount is called a “co-payment”.
