Guy Giorno practises public law with an emphasis on accountability and ethics laws, and leads our Government Ethics, Transparency and Political Law practice. He is Chair of the “Law of Lobbying and Ethics” committee of the Canadian Bar Association, is co-author of the legal text Lobbying in Canada and as a recognized expert in the law of lobbying routinely speaks, writes and advises clients on these, evolving, complex rules. He also serves as Integrity Commissioner and Lobbyist Registrar for the City of Brampton, and Integrity Commissioner for the Ontario municipalities of Durham Region, Dufferin County, Renfrew County, Amaranth, Brock, Clarington, Deep River, Dryden, East Garafraxa, Grand Valley, Horton, Madawaska Valley, Melancthon, North Algona Wilberforce, Orangeville, Pickering, Scugog, Shelburne, Uxbridge and Whitby.

Guy originally joined Fasken Martineau in June 2002. He rejoined the partnership in January 2011 after serving two and one-half years as Chief of Staff to the Prime Minister of Canada. He has been appointed a Fellow of the University of Toronto School of Public Policy & Governance, and a Fellow of Carleton University's Clayton H. Riddell Graduate Program in Political Management where he also teaches a Master's level course. He also serves as Certification Committee co-Chair and is a former Steering Committee member of the Council on Governmental Ethics Laws, and is an Executive Member of the National Administrative Law Section of the Canadian Bar Association.

Clients benefit from Guy's significant experience in public sector ethics, conflict-of-interest codes, accountability legislation (including freedom of information law), lobbyist registration law and election and election finance law. He is also versed in strategic communication, crisis communication and issue management and stakeholder relations.

During the 1990s he routinely represented public-sector institutions (respondents) in freedom of information appeals. Guy now focuses on compliance and best practices (helping institutions to achieve greater transparency and accountability) and on helping requesters to exercise their rights to obtain government records under freedom of information/access to information legislation.

While as a lawyer Guy continues to advise and represent public officials and participants in the political process (bringing to the table first-hand knowledge of their role and legal needs), to devote full attention to integrity and ethics work he is no longer personally active in partisan campaigns. On a non-partisan basis, he remains well-known as a strong advocate of government transparency, lobbying ethics and electoral reform.

Before joining the firm, Guy served as chief of staff and legal counsel to the 22nd Premier of the Province of Ontario. He founded and until 2008 he was the first national director of our Government Relations and Ethics group.

Guy's skill in writing has been recognized in two separate Ovation Awards conferred by the International Association of Business Communicators (Toronto). Much sought-after as a speaker, he has delivered presentations and speeches to numerous audiences and organizations. His analysis appears frequently in the media, including but not limited to Daily News, The Bottom Line, Briefly Speaking, CBC Metro Morning, CBC Newsworld, Education Today, CFRA's Michael Harris Live, CIUT, CKNW's Nightline BC, Charles Adler OnLine, Global TV's Focus Ontario, The Globe and Mail (Canada's national newspaper), The Hill Times, Hour Town (Pulse 24), The Lawyers Weekly, the Michael Coren Show, the National Post, News Talk 1010 (CFRB), Rhonda Live, Summit Magazine, TVO's Studio Two, the Toronto Star (Canada's largest circulation newspaper, where he used to write a weekly public affairs column), URC Investigates, Voice of the Province and the Western Standard.
