Narrative:

Air carrier ferry flight xyz yul to boston taxi to deice pad (taxiway H). During an extremely cautious and slow taxi (ice/snow/standing water) turning onto taxiway H, encountered zero braking capabilities while established in turn. Airplane was sliding and uncontrollable due to ice hidden under standing water. Reverse thrust and maximum braking were used. Due to heavy wind and the amount of ice, airplane taxied between taxi lights onto a paved shoulder of the taxiway. Because reverse was used, during taxi we requested airplane be towed, so an inspection of engines could be conducted to verify no FOD was ingested into engines. Tug, with assistance of sand truck, was available to position aircraft to allow for inspection. No damage to aircraft or airport facilities during taxi. 1 taxiway light was damaged during tug process. Airport employee noted that taxiway should never have been opened or used due to the ice conditions which covered the entire taxiway, vehicles, tugs and personnel could not operate due to ice conditions which were covered under standing water.
