Weyerhaeuser Canada, Lumby's history begins with a school teacher, a cost accountant and a grocer who decided to go into business for themselves when they were discharged from the armed forces in 1945.

      Brothers Ian and Harvey McDiarmid and their boyhood friend Ken Johnson went into partnership when they returned to Vancouver at the end of the second world war. By the end of 1950 the partners had built Merritt Forest Products, Rock Creek Forest Products and Lumby Planing mills.

      Since the start of Weyerhaeuser, the Lumby operation has had many changes. They now have 90 full time employees, approximately 25 part time and 20 salaried. All the logging and road construction done by contractors adds up to another 800 workers.
