The Shingle Mill was also the second home for Sam Sing, a respected business pioneer, who was the first merchant in Townsite. In 1923, after his profitable business was sold to the Powell River Company, he moved to the Shingle Mill. He opened another business that included a grocery, butcher shop, general merchandise and bachelor accommodations.
Sam Sing died in 1937 and his thriving business was carried on by his sons. The Penny Profit store, the last one operated by one of his children, closed its doors in 1987. Some of Sing's grandchildren have remained in Powell River.
As well as the Shingle Mill there were other small shingle bolt companies up and down the lake. Included are Olsen Landing, Goat Lake, as well as various camps operated by H. Nakamura who was interred in 1942 according to Federal Law.
