FOR IMMEDIATE RELEASE:

January 24, 2012

Pershing Square Announces Nominees for Election to the Board of Directors of Canadian Pacific Railway

NEW YORK, January 24, 2012 //- Pershing Square Capital Management, L.P. (“Pershing Square”), today announced its slate of five directors for election to the Board of Canadian Pacific Railway Limited (“Canadian Pacific”) (TSX: CP; NYSE: CP) at Canadian Pacific’s annual meeting of shareholders on May 17, 2012.

Pershing Square’s nominees, who will be proposed at the annual meeting of Canadian Pacific shareholders, are: Bill Ackman, Gary F. Colter, Paul C. Hilal, Rebecca MacDonald and Dr. Anthony R. Melman. Together they will add the experience and skills required to return Canada’s most historic railroad to a position of leadership in the railroad industry.

Commenting on the decision to offer a slate of seasoned business executives to strengthen the Board, Pershing Square CEO Bill Ackman said, “We’ve assembled a superlative slate of nominees who share our goal of ensuring that the Canadian Pacific remains independent and strong. With a revitalized board and new management, we will help CP transform from the worst to one of the best performing Class I railroads in North America.”

The Canadian business executives – MacDonald, Melman and Colter – bring a wealth of experience leading important national enterprises as well as serving as directors of leading charities and non-profit organizations. Each has broad and deep Canadian experience, both as executives and directors. Each of these executives is also independent of Pershing Square, with no prior business or personal relationship with Pershing Square or Ackman.

Ackman added, “We believe Canadian Pacific has a unique opportunity to benefit from the leadership of one of Canada’s great railroad executives, Hunter Harrison. As transportation experts and analysts have said in recent days, there is no executive who is as qualified to lead a turnaround of CP – to build value for shareholders and to improve performance for the hundreds of Canadian clients and communities it serves.”

Commenting on being offered an opportunity to rebuild and renew a second Canadian railway, Harrison said, “I’ve been a railroader since I was 19 years old. I love the industry, the people in it, its culture and the role we play in connecting customers and communities. I’m proud of the work we did at CN, and the positive impact that improving its performance had on shareholders, employees, customers and Canada. The great majority of Canadian Pacific’s employees are extremely talented and

dedicated. With the right board and executive leadership, I believe Canadian Pacific can achieve just as dramatic a turnaround and enjoy its rightful position as a leader in the North American rail industry. Together, we can transform CP into the railroad its customers, employees and shareholders deserve. I would be proud to help lead CP to that victory. Should the Board determine that I am the best candidate to lead the company, I would be honoured to serve.”
