sentences:  In Canada, rail lines from Labrador City, NL to Sept-Îles, Quebec also currently are not linked to the North American network.There have been proposals in recent years to link the island of Newfoundland to the mainland of North America via a 17 km-long rail tunnel under the Strait of Belle Isle, which would also carry automobile traffic on flatcars, similar to the Channel Tunnel between the United Kingdom and France.This has stalled due to the lack of a large road network and a lack of rail lines in Labrador, and the remoteness of the area on both sides of the strait in Newfoundland and Labrador.
