[Ontario] As of Apr 19, 2017 Nurse Practitioners May Prescribe Controlled Drugs and Substances

"Ontario was the last jurisdiction in North America to grant Nurse Practitioners the authority to prescribe controlled drugs and substances."

Also: "Nurse Practitioners (NPs) in Ontario can prescribe controlled substances, if they have completed approved controlled substances education. In the last five months, more than 80 percent of NPs have met this requirement and more are in the process."
