Esterhazy RCMP responded to the scene of a fatal collision on Highway 22 between the community of Gerald and the potash mine this morning.
A semi-tractor trailer, tow truck and two other vehicles were all involved.
The adult male driver of the tow-truck was pronounced deceased at the scene and his name will not be released.
One other adult male was transported to hospital with undetermined injuries.
The highway reopened this evening to traffic, but Mounties advise to check the Saskatchewan highway hotline prior to heading out.
The cause of the collision, or if weather is considered a factor has not been determined at this time.
