Finally, the Post Office was moved to a new building on Main Street and operated by Fred Bye who was also the contractor for construction of the White Bear United Church. Upon Fred's death, the Post Office and a small stationery store was carried on by his wife Mrs. Nellie Bye.
Upon Mrs. Bye's retirement, Mr. and Mrs. H. Newman filled the position as Post Master and once again moved to a new location in the Newman residence on the north side of Main Street.
