Hudson's Bay Co. post on East Bay, at the east end of lake Nipissing, Ontario, at the end of the portage from Trout lake via Vase river on the route from Mattawa to Georgian Bay. A short portage extended from the southwest bay of Trout lake to La Vase river and hence to East Bay. This was the historic route of the fur traders from the Ottawa river to lake Superior. There had been a small post here under the French regime and an Indian village. On Danville's map of 1755 (No. 97) lake Nipissing is called "Nipisirinis, or lac des Sorciers". A North West Co. post was located at mouth of Vase river, called Fort La Ronde. Before 1850 the Hudson's Bay Co. post was moved to one of the islands in lake Nipissing. After the construction of the Canadian Pacific Railway, the post was moved to North Bay about 5 miles to the north. Map No. 123 and 25.
