TCI Fund Management Ltd., a Canadian National Railway Co. shareholder, has sent a letter to the company's board alleging Canadian National Railway didn't disclose the resignation of a board member in a timely manner.

The fund, which sent the letter on behalf of itself and as investment manager of shareholders CIFF Capital UK LP and the Children's Investment Master Fund, on Wednesday said the timing for the disclosure of board member Julie Godin's Sept. 16 resignation raises corporate-governance concerns.

TCI, which owns about 5% of Canadian National, this month called for a special meeting to replace four Canadian National board members. The firm opposed Canadian National's bid to buy Kansas City Southern, which eventually struck a deal with Canadian Pacific Railway Ltd.

A Canadian National spokesman said news about Ms. Godin's resignation was posted on Canada's System for Electronic Disclosure by Insiders and on the company's website in a timely fashion. He said Ms. Godin resigned to focus on her expanding role as co-chairman and executive vice president for strategic planning and corporate development at CGI Inc.

A notice dated Sept. 16 detailing Ms. Godin's resignation was found Wednesday on Canadian National Railway's page for board mandate and committees, but was not found under the "News" section.
