In an interview on April 21, CP CEO Mr Hunter Harrison attacked the financial performance of other North American Class 1 freight railways, arguing that shareholder activism is "long overdue."

"Who's the advocate for the shareholder?" he asks. "If I was the shareholder, I wouldn't tolerate some of it."

Harrison was installed at the helm of CP in June 2012 following a proxy campaign by activist shareholder Mr Bill Ackman and his New-York-based hedge fund Pershing Square Capital Management.
