Narrative:

After normal landing runway 17 roc with reduced visibility conditions, the aircraft was brought to a complete stop. At that time we turned right to exit the runway. What appeared to be a normal taxiway that was snow covered was actually a grass area. Both pilots had the inclination that the aircraft was preceding properly. The aircraft came to a slow stop as it settled into unfrozen ground and become immobile. Roc tower coordinated all efforts to acquire a tow and provided services to deplane passenger and bags. No aircraft damage or passenger injuries occurred. Of interest to us was the use in canada of double blue lights at taxiway entrances. Such lights may be of help to crews in snowy conditions in identing the proper taxiway entrances.
