Narrative:

Upon getting takeoff clearance from runway 22; we taxied on to the runway. As the pilot flying I added power and called out 'set power'. Before the airspeed came alive; the left hi pack pres caution message appeared. The captain decided to pull the power back to idle and exit the runway to analyze the situation. Once we exited the runway; we quickly discovered the reason for the caution message was misconfigured bleeds. Since the right [air conditioning] pack had been deferred we were supposed to takeoff with bleeds closed. I swapped the bleeds to the engine by mistake before takeoff and the caution message appeared.
