 Wiltshire Park , Woodland , Oak Acres , <unk> Beach , Oakwood Corners , <unk> <unk> , and Blackwell , are part of the North End of Sarnia , which begins immediately north of Ontario Highway 402 and terminates at the shore of Lake Huron . Coronation Park , Heritage Park , College Park , The Tree Streets , and Sherwood Village are some of the neighbourhoods south of the highway . The village of Blue Water was built to house workers and their families in Chemical Valley during the construction of Polymer Corporation and at one point had nearly 3 @,@ 000 residents . In 1961 , all the residents were relocated , mostly to the North End , to make way for expansion of the chemical industry . The village was demolished , and all that remains now is an historical marker at the corner of Vidal Street and Huron Avenue . This neighbourhood was largely forgotten until historian Lorraine Williams penned two books about it and was instrumental in the dedication of the plaque .
