Adam Giambrone

In 2016, Mayor of New York City Bill de Blasio appointed Giambrone to head up the Brooklyn–Queens Connector (BQX) streetcar project.

Giambrone was the Ontario NDP's candidate for the August 1, 2013 provincial by-election in Scarborough—Guildwood. He placed third with 28% of the vote.

On July 5, 2013, Giambrone resigned as co-chair of the candidate search committee and announced his candidacy for the Ontario New Democratic Party's nomination for the August 1, 2013 provincial by-election in Scarborough—Guildwood; he won the nomination on July 7 over community activist Amarjeet Chhabra, reportedly by a margin of 18 to 14.

Giambrone came in third place with 28% of the vote, an improvement of 9% from the previous NDP candidate in the 2011 provincial election.

On February 1, 2010, Giambrone announced his candidacy to succeed David Miller as Mayor of Toronto in the 2010 election, as a leading progressive candidate, showing second place in polls after John Tory dropped out, though Giambrone also had a high "unfavourable" rating of 40%. Giambrone exited the mayoral race on February 10, 2010 amidst a sex scandal and he did not run for re-election for his council seat.

In the wake of a sex scandal (see 2010 mayoral campaign), fellow councilor Brian Ashton called for Giambrone to resign as chairman of the TTC, which had been beset by bad publicity. Ashton said "The TTC is under serious assault around issues of customer relations and performance. The union is now fragmented from the management. I think his moral authority has been totally debased and undermined," said Ashton. "I think mentally he's going to be distracted by both his mayoralty bid and this sex scandal. His ability to come to terms with the TTC issues is tremendously weakened." He did not step down, but also did not seek re-election and so his term as TTC chair ended in December, 2010.

Giambrone launched a campaign for Mayor of Toronto in the 2010 municipal election on February 1, 2010, ending it on February 10, 2010. Before Giambrone entered the race, two polls showed him in second place among declared mayoral candidates and he remained a leading candidate until February 9, when the Toronto Star published an interview with undergraduate student Kristen Lucas, who revealed that she had a past sexual relationship with Giambrone, including acts in his city office. Giambrone apologized for an "inappropriate relationship" and admitted to intimate relationships with women other than his live-in partner, to whom he is now married. In the immediate wake of the revelations, Giambrone initially pledged to continue with his mayoral campaign, but announced his withdrawal the following day.

On May 7, 2009, Giambrone sent an email from his mobile phone, warning fellow councillor Cesar Palacio to "stop messing in my ward" or face "problems". Giambrone apologized for the "hastily composed" email when Palacio distributed copies to local media.

On April 24, 2009, Giambrone announced that the TTC had opted to replace its aging fleet of Canadian Light Rail Vehicles and Articulated Light Rail Vehicles with 204 new streetcars, procured competitively from Bombardier Transportation. New streetcars began to enter service in 2012. The deal, valued at more than $1.2 billion, called for the streetcars to be manufactured in Thunder Bay.

Giambrone announced the launch of the TTC's Transit City Bus Plan on August 21, 2009. The plan took the 'network approach' of the Transit City Light Rail Plan and applied it to buses, creating a network of 10-minute service on 21 of its 139 bus routes which began in the fall of 2010.

Toronto Council unanimously approved a September 2007 motion to allow the Toronto Parking Authority to proceed with a plan to expropriate the Matador, a famed Toronto music hall and cultural landmark. After considerable media attention, an organised group of citizens, including noted author Michael Ondaatje and folk singer Sylvia Tyson, lobbied Giambrone to successfully reverse the expropriation.

Giambrone together with Mayor David Miller unveiled Transit City, a $10 billion expansion of light rail into neighborhoods and areas not served by rapid transit, and reaching into the GTA. Transit City calls for 120 kilometres of electric light rail along seven new routes. Premier Dalton McGuinty announced funding for Transit City as a component of its MoveOntario 2020 plan on June 15, 2007. Transit City was also included in Metrolinx's "Big Move" funding plan when it was released on November 27, 2008.

He announced in the summer of 2006 that he would not seek a third term as federal NDP president. Anne McGrath was elected to succeed him at the party convention in Quebec City.

Shortly after taking office, he was appointed as a commissioner of the Toronto Transit Commission (TTC). He also served along with Greater Toronto Area mayors and regional chairs on the board of Metrolinx from its inception in 2006 until 2009.

During the TTC workers' wildcat strike on May 29, 2006, Giambrone was prominent in the media representing the TTC's position as commission chair Howard Moscoe was out of town. After being re-elected in the 2006 municipal election, taking almost 67% of the vote in his ward, Giambrone was elected as Chair of the Toronto Transit Commission on December 6, 2006.

Giambrone continued his attempts to win the south Davenport seat on Toronto city council. When Silva left city council and was elected a federal Liberal Member of Parliament in Davenport in the 2004 federal election, Giambrone became a leading candidate to replace him in the 2003 municipal election. With the endorsements of the Toronto Star, Now Magazine, Bloor West Villager newspapers and councillors Joe Pantalone and Fred Dominelli, Giambrone defeated Ana Bailão, Silva's former assistant, by a 51-40 margin in a field of six candidates.

Seeking re-election at the 2003 convention at which Jack Layton was elected party leader, Giambrone faced a strong challenge from respected New Brunswick NDP leader Elizabeth Weir. Midway through the convention, Giambrone and Weir decided to seek a co-presidency. Many delegates balked, especially at the assumption that they could push through a sudden constitutional change in a party often dearly concerned with internal process. The joint ticket was withdrawn, and Giambrone won a second term against Weir and a challenger from the NDP Socialist Caucus.

At the federal NDP convention of 2001, Giambrone won a first two-year term as president of the party. He was a grassroots challenger to the "official slate" candidate customarily supported by the party brass, but the official slate candidate stood down in Giambrone's favour. The president of the NDP is the administrative chairperson of the party, chairing party conventions, councils and executive meetings. Giambrone was 24, and no younger person had ever become president (or leader) of a major Canadian party. He became a frequent guest on television and figure in the news, and travelled the country extensively speaking to New Democrats.

Returning to Toronto, he took up employment at the Royal Ontario Museum. He ran for Toronto City Council in the southern Davenport ward against Mario Silva in the 2000 municipal election, losing 6,037 to 3,338.

Growing up in the Davenport area of Toronto, he first became active with the New Democratic Party in its youth wing at age 15. While attending Harbord Collegiate Institute in Toronto, he was active in the model UN club and took great interests in politics. While studying at McGill University in Montreal, he served as treasurer of the New Democratic Youth of Canada. At age 20, he ran for the NDP in the riding of Mount Royal in the 1997 federal election, in which he finished fifth out of six candidates. He graduated from McGill with a bachelor's degree in archaeology.

Results for the 1997 federal campaign in the riding of Mount Royal:
