Minister of Finance Ontario Finance Minister Greg Sorbara unexpectedly resigned from office on 11 October 2005, after he was named on a Royal Canadian Mounted Police warrant issued in an investigation of his former real estate development firm. Later in the same day, Duncan was appointed to replace Sorbara as Minister of Finance and Chair of the Management Board of Cabinet. Duncan's first budget was introduced on 23 March 2006. It focused on infrastructure spending, and particularly new spending on public transit projects in the Greater Toronto Area including extension of the Yonge-University-Spadina subway line, and roads and bridges in other parts of the province. Health spending increased by $1.9 billion, and Ontario's universities were given $290 million more in operating revenue.

Toronto Hydro responded almost immediately by promising a fee reduction for consumers who cut their electricity usage by 10%. The project was successful, and Duncan announced in November 2006 that Toronto Hydro's conservation measures would be expanded across the province.
