CN announces US$700 million debt offering

MONTREAL, May 23, 2006 — CN today announced the terms of a US$700 million debt offering of US$250 million 5.80 per cent Notes due 2016, and US$450 million 6.20 per cent Debentures due 2036. CN expects to close the financing on May 31, 2006. 

CN plans to use the estimated net proceeds of US$692 million to reduce its accounts receivable securitization program and repay a portion of its outstanding commercial paper. 

The debt offering is being made in the United States under the shelf registration statement CN filed on May 9, 2006 for up to US$1.5 billion of debt securities. 

Lead managers of the debt offering are Citigroup Corporate and Investment Banking and J.P. Morgan Securities Inc. Other managers are Banc of America Securities LLC, Harris Nesbitt, Scotia Capital, BNP PARIBAS, RBC Capital Markets, and Wachovia Securities.






CN has filed a registration statement (including a prospectus) with the U.S. Securities and Exchange Commission (the SEC) for the offering to which this communication relates. Before you invest, you should read the prospectus in that registration statement and other documents CN has filed with the SEC for more complete information about CN and this offering.  You may get these documents for free by visiting EDGAR on the SEC Web site at www.sec.gov or by contacting J.P.
