Fort on the Assiniboine river, on east side, about 12 miles upstream from Fort Pelly and about 5 miles above the North West Co. Fort Alexandria. It was originally built by the X. Y. Co. in 1803 and was taken over and operated by the North West Co. after their union in 1803. The Hudson's Bay Co. after the union of 1821, continued to operate Fort Hibernia for some years as it appears in operation on the Arrowsmith maps of 1832 (No. 101), and 1850 (No. 100) and 1857 (No. 8). It was closed before 1869 as it was not included in the Hudson's Bay Co. list of 1869. The proximity of Fort Pelly (built 1857) probably rendered Fort Hibernia unnecessary.
