OHIP doesn't cover medications unless you are under 25 or over 65 or on welfare. If a large percentage of your income goes to medication and you have no insurance you may qualify for the Trillium drug program. They do cover you after you pay a significant deductible first (hundreds to thousands of dollars). Most people have the option of paying themselves or having work coverage after they receive OHIP.
Correct, OHIP don't cover medications , HOWEVER you have to talk to your doctor about exceptional access program, which is part of ODB.
