Lynn Lake is a town in the northwest region of Manitoba, Canada, approximately 1,071 km (665 mi) from Winnipeg. The town is the fourth-largest town in Manitoba in terms of land area. It is centred on the original urban community of Lynn Lake, located at 56°51′06″N 101°02′48″W / 56.85167°N 101.04667°W. The town was named after Lynn Smith, chief engineer of Sherritt Gordon Mines Ltd. There are many outfitters in the Lynn Lake area. They offer services for most wilderness experiences, including sport fishing and bear and moose hunting.
Lynn Lake was founded in 1950, when a deposit of nickel ore was discovered. The nickel mine was developed, and soon after, gold was also discovered. Most of Lynn Lake's 208 houses and commercial buildings were moved from Sherridon, Manitoba, over cat train trails. The houses and commercial buildings were moved by digging out the foundation, loading them on the tricycle winter freighting sleigh pulled by Linn tractors and caterpillar crawlers. The buildings once loaded were the last sleigh on the cat trains which were usually 4–5 sleighs long.
The Linn Tractors were used to move the town of Sherridon, Manitoba to Lynn Lake, Manitoba in the 1950s.
After a rich vein of copper ore had been nearly depleted in Sherridon, the company sent out prospectors to find another strike. Around 1945, the expeditions were successful when one of the world's largest nickel strikes was found near the soon to be established Lynn Lake. Most of the people of Sherridon moved to Lynn Lake when housing was completed.
