Mitsui Home Canada

Mitsui Home Canada Inc. (MHCI) was founded in 1992, as a wholly-owned subsidiary of Mitsui Home Co. Ltd.—the largest builder of 2x4 “platform-frame” single-family homes in Japan.

In 1994 MHCI built a manufacturing plant on a 12.5 acre property in Langley, B.C. for the purpose of purchasing, processing, inventorying, quality-controlling and shipping over 100 million board feet of lumber and 8 million square feet of OSB panels annually to its parent company in Japan.

Over the ensuing years, MHCI developed “custom services” in its lumber processing and export shipping businesses such that an additional 100 million board feet of lumber may be resorted, regraded, trimmed, repackaged and/or shipped annually by MHCI on a custom service basis.

In 2005 MHCI added panelized manufacturing and construction capability to its domestic business and has supplied over 9000 units of residential construction in single family, condominium and townhouse project throughout British Columbia in Canada and Seattle and Northern California in the US.
