    "Engineering firms in Vancouver were faced, between 1985 to the present, with the task of rebuilding the ¡®leaky condos¡¯ of the Lower Mainland. A series of degradations of building practice and material durability led to what has become the biggest and most costly reconstruction of housing stock in Canadian history. For those not familiar with the wood-framed condominium stock, it consists mainly of platform framed condominiums, three or four storeys in height, clad with a variety of products but mainly stucco."

    Report says officials still don't know "the full extent of building envelope failure."

    William Boei, Vancouver Sun, Published: Wednesday, July 09, 2008

    Coastal British Columbia's leaky condo crisis is far from over, a recent report prepared for the provincial government shows.

    The report acknowledges for the first time that thousands more strata-owned apartment units suffered water damage than the government has been estimating.

    By 2012, when the leaky condo era enters its fourth decade, as many as one-third of the defective units will remain unrepaired, said the report, prepared for the province's Homeowner Protection Office (HPO) by private consultants.
