The Saint Lawrence Hydrographic Service has studied the tides for the benefit of sailors and fishermen for many years. In fact, a daily tide reading was taken as early as 1893. The compilation of all of these data has made it possible to start making tide predictions.
Today, information on the tides along the Saint Lawrence is available thanks to the Hydrographic Service of Canada.
Consult the Hydrographic Service of Canada for the tide schedule at the location of your choice.
