Aircraft
Climbing through 13;000 ft. we got an 'Elevator Split' caution message. I continued to fly the airplane and took the radios while the Captain ran the QRH. The QRH directed us to land at the nearest suitable airport. We decide to return to ZZZ and [requested priority handling] since we had a flight control issue. After completing the QRH the Captain notified the cabin crew and passengers. We also notified ZZZ Operations of our return. Once we were ready to land the Captain took control of the aircraft. Our approach; landing; and taxi to the gate was uneventful.
Air Carrier First Officer reported an 'Elevator Split' caution message during initial climb. The flight crew returned to the departure airport and executed a safe landing.
