Montreal-based Domtar Inc. has completed a merger with the fine paper business of U.S. forest giant Weyerhaeuser Co., creating a company called Domtar Corp.

The new Domtar has a head office in Montreal and an operations centre in Fort Mill, S.C, a company statement said Wednesday. 

The backbone of its operations is a string of six highly efficient uncoated freesheet mills that provide two-thirds of its annual capacity, it said.

"With a strong team of nearly 14,000 employees dedicated to creating value for customers and shareholders, a world-class manufacturing capability and a solid financial position, Domtar becomes the North American leader in the fine paper business," president Raymond Royer said in the statement.

As of Wednesday, Domtar Corp. common shares are listed on the New York and the Toronto stock exchanges under the ticker symbol UFS, it said. The common shares of Domtar Inc. (symbol DTC) have been delisted from both exchanges.
