Just to add to that, you would probably be surprised at the exclusions. Only certain drugs are covered under the list, and that's if you qualify under Ontario Works or ODSP.
Just as an example, diabetic medications are covered but not the newer ones. The ones that are most efficacious and are related to the fewest side effects are not covered. Strips for the diabetic monitors are not covered. So if you want somebody to be well controlled, like someone with diabetes, you want them to be checking their blood sugar, but many people will not be able to afford the strips, which cost $1 each, on average.
Another piece that's not covered is dental care. I have many clients who have access to food but can't eat the food because they don't have dentures.
