Narrative:

Approaching teb for landing; we were informed by ATC that the airport was closed for snow removal. We were assigned a holding pattern. Approximately 30 minutes later we were cleared to the airport for an ILS runway 19 circle to land runway 24. The ATIS weather information was reporting marginal VFR conditions with winds 310/11. Braking action on runway 24 had been reported as good. No taxiway advisories were noted. Approach and landing were entirely normal runway 24 had patches of snow but breaking action was good. We exited the runway at taxiway Q. I noted on the first left turn that the taxiway was very slippery with minimal braking however the aircraft remained in control as we began the second left turn. The co-pilot (pilot not flying) advised ATC of the taxiway condition. During the second left turn onto taxiway Q we experienced a complete loss of braking action and steering capability due to the ice. The nose of the aircraft continued to veer to the left. I applied thrust reversers to slow the forward momentum however the left main gear slid off of the left edge of the taxiway. As the aircraft continued forward movement the nose wheel also departed the paved surface area. The right main gear remained on the taxiway. There were no injuries and no apparent damage to the aircraft. It should be noted that the first airport operations vehicle to respond lost control on the icy pavement and spun in a circle before stopping close to the aircraft. Further examination of the taxiway surface revealed a layer of clear polished ice approximately 1/4 inch thick across the entire width of Q. No chemical surface treatment was apparent.

Title: CL65 flight crew lands on Runway 24 after it is cleared of snow to find good braking action. Upon entering Taxiway Q control is lost due to icy conditions and aircraft slides off taxiway.
