Getting prescription drugs How do I get a prescription filled through the Ontario Drug Benefit (ODB) Program? To have a prescription covered through the ODB Program, it must come from a health care provider licensed to practice and prescribe drugs in Ontario, and the product must be a benefit of the ODB Program. You will take your prescription to a drug store in Ontario to get it filled. Make sure you tell the drug store staff that you qualify for the ODB Program. The ODB Program will pay most of the cost of more than 3,800 prescription products (known as ODB benefits) if you qualify for the program.  You will be responsible for paying a small portion. Do I have to get my prescription(s) filled in Ontario? Yes. The ODB Program does not pay for prescriptions you get filled outside the province. What if I forgot to tell the drug store staff that I am an Ontario Drug Benefit recipient? If you did not tell the drug store staff that you were an Ontario Drug Benefit recipient, you may have paid for your drug. You can send your prescription receipt(s) to the ministry for reimbursement, if the drug is an ODB benefit. You can call the drug store to check if the drug is an ODB benefit. On your next visit to the drug store you should inform the drug store staff that you are eligible for the Ontario Drug Benefit Program. How do I get my prescription receipts reimbursed
