John Garth Turner PC is a Canadian business journalist, author, entrepreneur, broadcaster, financial advisor, and politician, twice elected as a Member of the House of Commons, former Minister of National Revenue and leadership candidate for the Progressive Conservative Party of Canada.

After serving as a PC MP between 1988 and 1993, he returned to political life as a candidate for the Conservative Party of Canada in the 2006 federal election, beating Liberal Gary Carr in the riding of Halton, Ontario.

He also worked as an editor for The Globe and Mail, Metroland Publishing and Thomson Newspapers, and helped launch Maclean's as a newsweekly magazine.

After his election loss, Turner returned to journalism, becoming a business editor for Baton Broadcasting and then the CTV Television Network and authoring a series of books on real estate and personal finance.

Turner served as national director of the Vancouver-based Sierra Legal Defence Fund, an organization dedicated to upholding environmental laws, resigning after his return to the House of Commons.

In 2009, Turner launched an online retail operation, xurbia.ca, offering renewable and alternative energy products and equipment, as well as preparedness supplies, citing climate change[5] and the ongoing economic downturn as precipitating factors.

[citation needed] Turner also returned to his national speaking tours, focusing on investor education in a string of events once again sponsored by prominent companies in the financial services sector.

After a period of introspection and deliberation, on February 6, 2007, Turner surprised many observers by joining the Liberal Party caucus at the invitation of its leader, Stéphane Dion.

It is an account of his experiences within and without the caucus of the Conservative Party, and the clash between backroom-style politics and the open blogging Turner pioneered as a web-based MP.
