in 2007. The Canadian branch plant of the Plymouth Cordage Company was started in 1904 due to Parliament's initiation of a 25% import duty on rope and related products. Plymouth, with roots in Massachusetts, moved to secure its business in binding twine, necessary to package farm crops such as grass, wheat or straw. The city of Welland grew up around the Plymouth plant, which was prior to 1904, farmland. The cordage industry was a victim of the harvester-thresher, which obviated the need for binding (or baling) twine, as the threshing operation is now performed in a contiguous step immediately when the stalk is cut. Welland's electricity comes from the Sir Adam Beck hydroelectric generation plants at Niagara Falls via Welland Hydro. Thanks to the presence of the massive plant, power remained on in over half of Welland during the 2003 North America blackout until rolling blackouts began the next day in an effort to provide power to areas that hadn't had it for nearly 24 hours. Geography Welland is located in the centre of south Niagara. Over the years, urban growth has all but united the northwest part of Welland with the community of Fonthill. Prior to the Welland By-Pass project, the Welland Canal cut through the centre of Welland. As a result, a very prominent split was created between the east side and the west side of the city. The west side grew primarily to the north, while the east side expanded south. The west side also became the more affluent of the two. Today, even though the canal traffic no longer causes regular interruption in the traffic across the city, the channel lives on as Welland Recreational Waterway. The waterway still serves as a very prominent visual feature dividing the city, and it is perhaps for this reason that the east side/west side division is still very much alive in the minds of Wellanders. East side and west side are very commonly used as basic directions. The communities of Cooks Mills and Dain City have their own separation stories. Cooks Mills, located on the other side of the By-Pass channel than the rest of Welland, has arguably been protected against the impact of urban sprawl, but the necessity of using one of the two highway tunnels to cross the canal causes some residents to head to nearby Niagara Falls instead. Dain City, located in the south of the
