The Ontario Trillium Drug Plan (OTDP) provides drug coverage for eligible Ontario residents. This calculator helps you estimate your monthly drug benefits based on your income and family size.
How the Ontario Trillium Drug Benefit Works
The Ontario Trillium Drug Plan is a provincial health insurance program that provides coverage for prescription drugs. Eligible residents pay a monthly premium based on their income and family size, and in return receive coverage for prescription medications.
Eligibility Requirements
To be eligible for the Ontario Trillium Drug Plan, you must:
- Be a resident of Ontario
- Be a Canadian citizen or permanent resident
- Have a valid Ontario Health Insurance Plan (OHIP) number
- Meet the income requirements for your family size
Income-Based Premiums
The monthly premium you pay depends on your household income and the number of people in your family. The Ontario government sets income brackets that determine your premium amount.
Important Note
Income requirements and premium amounts are updated annually. The calculator uses the most recent published rates, but you should verify your eligibility with the Ontario government or your local health unit.

Formula Used
Calculation Method
The Ontario Trillium Drug Plan premium is calculated using the following formula:
Monthly Premium = (Annual Household Income ÷ 12) × Premium Rate
The premium rate is determined based on your income bracket and family size. The calculator uses the most recent published rates from the Ontario government.
Worked Example
Let's look at an example to see how the calculator works. Suppose you have a family of four with an annual household income of $60,000.
Step-by-Step Calculation
- Annual household income: $60,000
- Family size: 4
- Monthly income: $60,000 ÷ 12 = $5,000
- Based on the income brackets, a family of four with $60,000 income would fall into the middle bracket
- Premium rate for this bracket: 1.5%
- Monthly premium: $5,000 × 1.5% = $75
In this example, your estimated monthly premium would be $75. The actual amount may vary slightly based on the exact income brackets and rates in effect for the current year.
| Family Size | Income Bracket | Premium Rate | Example Premium |
|---|---|---|---|
| 1 | $25,000 - $30,000 | 1.0% | $25 |
| 2 | $35,000 - $45,000 | 1.2% | $54 |
| 3 | $45,000 - $55,000 | 1.4% | $70 |
| 4 | $55,000 - $65,000 | 1.5% | $75 |
