Narrative:

Normal start to day. Loaded passengers; did originating checks; then taxied to de-ice. Started type 1 at XA27L and finished at XA35; 55/45 mix; type 4 started at XA38 finished XA40. On taxi out the pilot not flying did one control check; prior to crossing hold line while waiting for our wheels up time of XA50 I did a control check. Taxi in position and hold. Another control check was accomplished with the before takeoff checks. Held brakes for approximately 20 seconds with power up to 45-50%. Released brakes; controls were neutral and felt good. Could not rotate at vr. Pulled very hard on controls with no response. Did not feel safe and comfortable continuing the takeoff with apparent stuck controls; so I elected to reject the takeoff. The nose wheel broke ground at the same time I made the decision to reject the takeoff and was retarding the power. We brought aircraft to a stop on the runway. Reported the rejected takeoff to tower and the problem and taxied back to the gate. The controls in my opinion felt normal for the conditions we were operating in until I applied back pressure to get the aircraft off the ground; and then the controls did go back; but the back pressure required to bring the controls back further increased in proportion with the position of the yoke; until I could not move the controls anymore. Do not fly in questionable weather. Try to recognize what aircraft feels like with type 1; type 4 and what is considered as a questionable amount of force to rotate the aircraft under the current conditions.

Title: A DHC-8-300 was unable to rotate at Vr subsequent to deicing with Type IV fluid approximately 10 minutes prior to starting the takeoff roll. The flight crew rejected the takeoff just as the nose gear had lifted off on its own due to airspeed increasing. Elevator control checks were normal before and after the event.
