Lambton County OPP say the body of a male has been found in the St. Clair River south of the Blue Water Bridge.
The body was found around 11:30 a.m. on Monday, four days after police received reports a man had jumped.
Police began searching on Thursday, after receiving calls that a vehicle had been abandoned in the westbound span of the bridge and that the driver had jumped into the St. Clair River.
The search has included several OPP units, Sarnia police and fire crews and the U.S. and Canadian Coast Guard.
A post mortem is scheduled for Tuesday.
