L.S.W. has been supplying aftermarket parts to the mining, construction, forestry and energy industries since 1993.
This year, to support growth of its business and to accommodate Metso's customers, the company is also opening a new bend and band facility.
The distributor currently operates from two locations in Fredericton, New Brunswick, and Truro, Nova Scotia.
L.S.W. president Gregg Carr said: "The Metso line of products coupled with our new bend and band facility only furthers our commitment to better facilitate solutions for existing and new clients."
The company also supplies wear parts from Weir Group, Hardox and Domite.
Jean Hebert, vice president, services sales Canada at Metso, believes through the partnership it will offer Canadian customers "added-value screening solutions".
