The Great Recycling and Northern Development (GRAND) Canal of North America or GCNA is a water management proposal designed by Newfoundland engineer and visionary Thomas Kierans to alleviate North American freshwater shortage problems. It proposed damming James Bay, using the techniques of the Zuiderzee/IJsselmeer, to prevent its waters mixing with the salt water of Hudson Bay to the north. This would produce an enormous freshwater lake, some of which would be pumped south into Georgian Bay where it would increase the freshwater levels of the lower Great Lakes. The flow would be the equivalent to 2.5 Niagara Falls.
The plan was promoted by Kierans from 1959 until his death in 2013 and since by his son, Michael Kierans. This plan arose as water quality issues threatened the Great Lakes and other vital areas in Canada and the United States. Kierans proposed that to avoid a water crisis from future droughts in Canada and the United States, in addition to water conservation, acceptable new fresh water sources had to be found.
During the 1960s and again in the 1980s when Great Lake water levels declined dramatically, there was interest in the GRAND Canal. However, the reluctance of the US and Canadian governments to enter into large scale co-operative international water sharing arrangements and claims of potential negative environmental impact of the proposal have prevented serious consideration of the idea.
