Narrative:
Given takeoff clearance from 21R in dtw behind a 757 before the aircraft had finished rotating. I turned on continuous ignition in case of wake turbulence encounter. We got a small jolt of wake turbulence at 200-300 ft AGL. At less than 1000ft; we encountered significant wake turbulence requiring full deflection of roll controls at least 3 times. I saw the 757 had turned left and told the first officer (first officer) to ask for runway heading to get out of the turbulence. When the first officer advised the tower; the reply was 'there is no wake turbulence.' I informed the controller that we had been full deflection on the flight controls to counter the turbulence. He then gave us runway heading. The tower no longer [provides] wake turbulence separation on 757s. Provide wake turbulence separation on 757s.

I saw the 757 had turned left and told the First Officer (FO) to ask for runway heading to get out of the turbulence. When the FO advised the Tower; the reply was 'there is no wake turbulence.'
