• Canadian Tide Tables
  The Canadian Tide & Current Tables are maintained by the Canadian Hydrographic Service. As of April 30th 2003, the Tidal Predictions Web Site has been revamped to include an increased variety of information on tides, currents and water levels in Canada. Tidal predictions (predicted times and heights) for approximately 700 Canadian locations are available. High and low tides, as well as hourly height values are presented in graphical, tabular and text format for 7 day periods up to a year in advance or within the past year. It is also possible to access water level height information based on data from the CHS permanent network of gauging stations, located throughout the Great Lakes, St. Lawrence River, Hudson Bay as well as the Arctic. These gauges are operated by the Tides, Currents and Water Levels section in CHS Central and Arctic Region.
