1) Today, the Labrador region has no west coast, only an east coast. The Labrador Peninsula has a west coast on the Hudson Bay, but I would rather call this the west coast of Quebec. 2) "Labrador is a region of Atlantic Canada. Together with the island of Newfoundland from which it is separated by the Strait of Belle Isle, it constitutes the province of Newfoundland and Labrador. The region is part of the much larger Labrador Peninsula on the Canadian mainland. The area was known by the Norse as Markland." "Coastline: 7,886 km (4,900 mi)" Source and further information: http://en.wikipedia.org/wiki/Labrador 3) "'08, M. E.—Francis Salisbury Adams is a member of a party of four which is exploring the unknown west coast of Labrador for the Canadian Geological Survey for possible mineral development in the future. The party started about July 1 from a station on the Canadian Pacific Railway north of Lake Superior, and canoed down the Missanabie and Moose rivers to Moose Point, a post of the Hudson Bay Company at the southern end of Hudson Bay. This trip took eighteen days and was a hard one, because the rivers are large and full of rapids and the canoes were heavily loaded. From Moose Point the explorers were to take a sailboat and coast down the east side of Hudson Bay about 600 miles, returning the same way to Moose Point and thence crossing Canada again by canoe, going up the Abittibi river system and coming out finally in the cobalt district at Hailibury, Ont., which they expect to reach in October."
