The Thames River features in many of the highlights of this timeline section; primarily related to either the threat of flood or control measures undertaken. For example, a point of land at the London Rowing and Boating Club was removed and the river dredged. The Upper Thames Valley Conservation Authority was established and the Fanshawe Dam built. Housing initiatives included the construction of 186 units at Bellwood Park and a new facility for senior citizens (Dearness Home) opened. A municipal transit system was created with its operations handled by a Transportation Committee. Construction and re-construction of water treatment facilities occurred at the west and east end of the city and the sewer system extended. Storybook Gardens was created in Springbank Park and an arena and the coliseum added to the grounds of Western Fair. In addition to HM Queen Elizabeth II and H.R.H. the Duke of Edinburgh, London was host to a wide array of visiting Canadian and foreign dignitaries among them a French ambassador and former Chancellor of Austria.
