Following its initial acquisition of the assets of Doman in 2004, the Company undertook a series of restructuring activities including the closure of its Silvertree sawmill in 2005, the exit from the pulp business in early 2006 and ceasing operations at the Duke Point log merchandiser, which was used primarily to supply whole log wood chips to the Company's former Squamish pulp mill.

On May 1, 2006, Western acquired all of the issued and outstanding shares of Cascadia from Trilon Bancorp Inc., a wholly owned subsidiary of BAM, for cash consideration of $202.2 million.

Cascadia was, at the time, the largest Crown tenure holder in coastal British Columbia, with an AAC of approximately 3.6 million cubic metres, and one of the largest lumber producers on the British Columbia coast, owning or operating four specialized sawmills with an aggregate annual production capacity of approximately 570 million board feet of lumber, a "custom cut" division and four remanufacturing facilities.

Recovery rates of lumber produced from logs have been increased with the benefit of previous capital investments and refined sawmilling techniques.

Further restructuring took place in 2009 and into 2010 to address the continuing weak worldwide lumber markets, resulting in further organizational changes, plant down-time, headcount reductions and the relocation of the Company's corporate office to Vancouver.
