Executive Biography:

Dwight Duncan is the MPP for Windsor–Tecumseh. He was first elected to the Ontario legislature in 1995. He was appointed as Minister of Finance and Chair of the Management Board of Cabinet in 2005, and as Deputy Premier in October 2011.

Minister Duncan has previously served as Minister of Energy and Chair of Cabinet, as well as Government House Leader. As Minister of Energy, Duncan brought meaningful change to Ontario’s electricity sector, fostering a culture of conservation, while ensuring a reliable, sustainable, diverse and affordable power supply.

As Minister of Finance, Minister Duncan oversaw Ontario’s response to the global economic crisis, the worst since the Great Depression, by introducing a stimulus and job-creation plan in the 2009 Ontario Budget. This response included substantial support for Ontario’s auto sector, a major employer and economic contributor in the province.

He modernized Ontario’s tax system, with tax relief for both people and businesses, and replaced the inefficient provincial sales tax with the harmonized sales tax (HST). Minister Duncan introduced the first major reforms to the pension and retirement income system in over two decades and is leading the call for reforms at the federal level. In 2012, he has introduced a strong action Budget to eliminate the deficit to grow the economy, create jobs and protect front-line public service for Ontario families.

Duncan is a lifelong resident of Windsor. From 1987 to 1995, he served as an administrator at Brentwood Recovery Centre, Canada’s largest alcohol and drug recovery centre. He sat on Windsor City Council from 1988 to 1994.
