Following his defeat in 1997,[3] Dingwall was given an honorary Doctorate of Laws from the University College of Cape Breton, recipient of the Connaught Award presented by the Canadian Lung Association.
On February 27, 2003, the Government of Canada appointed Dingwall to the position of president and chief executive officer of the Royal Canadian Mint.
On leaving the Royal Canadian Mint, Dingwall called for an independent audit which was completed by PricewaterhouseCoopers who found "the expenses fell within the guidelines".
[6] A second independent review by the law firm of Osler, Hoskin and Harcourt found that the Mint's process for monitoring expenses were stricter than those of most private corporations.
[7][8] On or about February 4, 2006, retired Superior Court Justice George Adams found that the Government of Canada essentially forced Dingwall out when he released his findings in a binding arbitration ruling.
