In Ontario, prescription requirements for controlled substances vary according to their classification in the Controlled Drugs and Substances Act. Schedule I substances are tightly regulated and require a prescription for dispensing, which includes narcotics and other controlled substances that have a higher potential for abuse and dependability.

Schedule II and Schedule III medications, while they can be obtained without a prescription, are classified as over-the-counter medications that may be kept behind the pharmacy counter or may need pharmacist intervention for dispensing.
