How has the Rideau been recognized?
In 1925 the Rideau was designated a National Historic Site of Canada (plaqued in 1926). In 2000 the Rideau Waterway was designated a Canadian Heritage River in recognition of its outstanding historical and recreational values. In 2007 it was inscribed as a UNESCO World Heritage Site recognizing it as a work of human creative genius. The Rideau Canal was recognized as the best preserved example of a slackwater canal in North America demonstrating the use of European slackwater technology in North America on a large scale. It is the only canal dating from the great North American canal-building era of the early 19th century that remains operational along its original line with most of its original structures intact. It was also recognized as an extensive, well preserved and significant example of a canal which was used for military purposes linked to a significant stage in human history – that of the fight to control the north of the American continent.
