The Eau Claire and Bow River Lumber Co. building, an important piece of Calgary’s history, has been moved once again, but now sits at the spot it’s expected to stay indefinitely. … The Eau Claire and Bow River Lumber Co. was established in Calgary in 1886. The company soon grew to become the largest supplier of lumber in the Northwest Territories, and eventually became the parent company of numerous other local industrial firms, including the Calgary Iron Works, the Calgary Milling Co. and the Calgary Water Power Co. Ltd. The building, which was actually the second office erected by the lumber company, was built in 1903/1904. …The building has excellent historical significance for being the sole survivor of this important group of companies that involved prominent Calgary businessmen.
