We have significantly useful tidal reserves on the British Columbia coast, in New Brunswick, and in Nova Scotia. Smaller amounts may be in Newfoundland, and there are potentially some in northern Quebec and in Nunavut. Whether we can use the energy in the north is probably debatable. Some remote communities in the north may be close enough to tidal resources up there.
The forecast we are working with is the one that the National Round Table on the Environment and the Economy has used, and that is that there would potentially be a total of about 15,000 megawatts of wave and tidal available on the three coasts of Canada by 2050.
