TORONTO - Forestry and flooring manufacturer Sino-Forest stock saw the suspension of trading in its stock extended until January 25 by Canadian authorities.

The engineered wood flooring maker's CEO Allan Chan quit in August amid a continuing investigation by the Ontario Securities Commision, which first suspended trading last month.

Toronto-based Sino-Forest, which manufactures flooring in China from its own plantations, began encountering trouble after its business was described as a Ponzi scheme by investment analyst  Muddy Waters.
