The search for the world of the domination of tide led to a competition between the basin of the Mines in bay of Fundy and the basin of Leaf to the bay d' Ungava, on which the body of l' water is prevailed of the highest tides of the world, with supporters of each area which asserts the record.

The hydrographic Service of Canada finally declared it a statistical bond, with measurements of meter 16,8 (55,1 feet) l' amplitude of the tides in the Leaf basin for the bay d' Ungava and 17 meters (55,8 feet) with Burntcoat direction of Bay of Fundy. [6] Highest level d' water ever recorded in bay of Fundy, the system s' is produced with the head of the Minas basin, in the night of the October 4, 1869 to the course d' a tropical cyclone named the “Saxby Scale”. The level d' water of 21,6 meters (70,9 feet) results from the combination of strong winds, abnormally low atmospheric pressure and a spring tide.

The basin with the Sheets n' was measured during the recent years, whereas the system of Fundy was measured during several decades. Tidal experts to note that the Leaf basin is systematically higher on average than on the tides of the basin Minas, however, highest recorded ever measured l' amplitude of the tides are in Burntcoat chief and result from spring tides measured at the top of the cycle of the tides every 18 years.
