Top speaking fee: $525,000

The most beloved living former U.S. president, Bill Clinton is a hot draw around the globe, but it was Canada, of all countries, that paid the Democrat his highest lecture fee. Clinton, who earned a reported $40 million for speeches between 2001 and 2007 and a further $6 million in 2008, signed up for five engagements in 2008 with Toronto-based Power Within Inc., a company that holds motivational and training programs in North America. Clinton received $1.25 million in his deal with Power Within, including a whopping $525,000 cheque he was awarded for a speech in Edmonton in June 2008, the former Commander in Chief's most lucrative private appearance to date.
