The McGuinty ministry was the combined cabinet (formally the Executive Council of Ontario) that governed Ontario from October 23, 2003, to February 11, 2013. It was led by the 24th Premier of Ontario, Dalton McGuinty. The ministry was made up of members of the Ontario Liberal Party, which commanded at first a majority and later a minority in the Legislative Assembly of Ontario.
The ministry replaced the Eves ministry following the 2003 Ontario general election. The ministry governed through all of the 38th and 39th Parliaments of Ontario, as well as just over a year of the 40th Parliament of Ontario; after the Ontario Liberal Party secured only a minority in the 2011 election, McGuinty eventually resigned, and was succeeded as Premier of Ontario by Kathleen Wynne.
History
{{more citations needed|section|date=January 2025}}
=The McGuinty Cabinet is formed=
Dalton McGuinty's first cabinet{{cite web|url=https://news.ontario.ca/en/release/3780/mcguinty-government-takes-office-ready-to-get-to-work-for-all-ontarians/|title=McGuinty Government Takes Office; Ready To Get To Work For All Ontarians|website=news.ontario.ca|access-date=October 22, 2024}} was sworn in October 23, 2003. It was comprised of 23 members.
There were several instances of ministerial portfolio reorganisation as McGuinty took over from Eves:
- Ministry of Children, Community and Social Services was divided into two ministries: the "Ministry of Children's Services" (renamed "Ministry of Children and Youth Services" in 2004), tasked with implementing the government's Best Start Plan and early childhood education commitments; and the "Ministry of Community and Social Services".
- Ministry of Enterprise, Opportunity and Innovation was reorganised into the "Ministry of Economic Development and Trade," as it was restored to the role and to the name that it had held before.
- Ministry of Public Safety and Security was renamed "Ministry of Community Safety and Correctional Services".
- A new secretariat, headed by a "Minister Responsible for Democratic Renewal" (not a cabinet level position in its own right) was also created to improve participation in the democratic process by the youth and broader public.
- all "Associate Ministry" positions were eliminated, and McGuinty did not at first appoint any ministers without portfolio.
Thus the McGuinty ministry began with 23 cabinet members serving in 25 portfolios (including the Premiership). Two cabinet members held multiple portfolios.
=2005=
==First Midterm Shuffle==
McGuinty's first cabinet shuffle occurred June 29, 2005,{{cite web|url=https://news.ontario.ca/en/release/4960/premier-mcguinty-fine-tunes-his-cabinet-at-mid-term/|title=Premier McGuinty Fine Tunes His Cabinet At Mid-Term; Plan To Strengthen Education, Health And Prosperity Of Ontarians Reflected In New Responsibilities|website=news.ontario.ca|access-date=October 22, 2024}} about four months before reaching the midway point of his first mandate.
None of the established cabinet ministers stepped down from the ministry, but eight of them moved into a new role.
There were several instances of ministerial portfolio reorganization, all involving established cabinet ministers:
- Ministry of Research and Innovation was created.
- Ministry of Health Promotion was created, dedicated to promoting healthy living and illness prevention.
- Ministry of Government Services was created to improve human resources management and internal government operations. It also absorbed the "Ministry of Consumer and Business Services."
- Chair of the Management Board of Cabinet ceased to be a cabinet level position in its own right; many of its areas of responsibility were transferred to the new "Ministry of Government Services." Henceforth "Chair of the Management Board" would be the title of the head of a cabinet committee, and always exercised by whoever held the position of Minister of Finance.
Thus, the number of portfolios swelled to 26 (including the Premiership), held by 25 cabinet members.
==Sorbara Scandal==
Months later, the first high-profile cabinet scandal rocked the McGuinty ministry as Greg Sorbara resigned as Minister of Finance October 12, 2005, when it was revealed that he was named as a target in the criminal fraud investigation by the RCMP of Royal Group technologies Inc.{{cite news|url=https://www.theglobeandmail.com/news/national/sorbara-quits-under-cloud/article18250090/|title=Sorbara quits under cloud|newspaper=The Globe and Mail|date=October 12, 2005 |access-date=October 22, 2024}}
Dwight Duncan took over from Sorbara as Finance Minister. Duncan remained Cabinet Chair, but established cabinet minister Jim Bradley took the role of House Leader from him. Duncan was replaced as Minister of Energy by newly appointed cabinet minister Donna Cansfield. Her addition to the ministry brought the number of women serving to seven, as Laurel Broten had also been added in the shuffle earlier in the year; placing more women in cabinet positions was reported to be a priority for McGuinty.{{cite news|url=https://www.theglobeandmail.com/news/national/mcguinty-shuffles-cabinet/article20423722/|title=McGuinty shuffles cabinet|newspaper=The Globe and Mail|date=June 29, 2005 |access-date=October 23, 2024}}
=2006=
==Kennedy Departs==
McGuinty lost a second high-profile cabinet minister on April 5, 2006, when Gerard Kennedy stepped down as Minister of Education to pursue the leadership of the federal Liberal Party.{{cite news|url=https://www.theglobeandmail.com/news/national/mcguinty-to-shuffle-cabinet-as-kennedy-pursues-dream/article1097471//|title=McGuinty to shuffle cabinet as Kennedy pursues dream|newspaper=The Globe and Mail|date=April 5, 2006 |access-date=October 23, 2024}}
In a shuffle involving two other cabinet members,{{cite news|url=https://news.ontario.ca/en/release/4844/statement-by-premier-dalton-mcguinty-on-gerard-kennedy-and-cabinet-shuffle//|title=Statement By Premier Dalton McGuinty On Gerard Kennedy And Cabinet Shuffle|newspaper=news.ontario.ca|date=April 5, 2006 |access-date=October 23, 2024}}
Kennedy ultimately failed to secure leadership of the federal Liberal Party.
==Sorbara returns==
McGuinty recovered a valued colleague when Greg Sorbara was cleared of fraud charges and restored to his role as Minister of Finance on May 23,.{{cite news|url=https://www.cbc.ca/news/canada/toronto/sorbara-returns-as-finance-minister-after-cabinet-shuffle-1.589120|title=Sorbara returns as finance minister after cabinet shuffle|newspaper=CBC|date=April 5, 2006 |access-date=October 23, 2024}} In a minor shuffle involving only two other cabinet members, a new porfolio was created:
- Ministry of Small Business and Entrepreneurship, a post similar to the "Ministry of Consumer and Business Services" that had been eliminated nearly a year previous.
==Wynne Joins==
On September 18, Joseph Cordiano stepped down as Minister of Economic Development and Trade, retiring from the ministry and from parliament for personal reasons.{{cite news|url=https://www.sootoday.com/local-news/dalton-dave-shuffle-their-cabinet-105080//|title=Dalton & Dave shuffle their cabinet|newspaper=Soo News|date=September 18, 2006|access-date=October 23, 2024}}
Days later, September 21, McGuinty named George Smitherman to the until-now vacant post of Deputy Premier.{{cite news|url=https://news.ontario.ca/en/release/4501/george-smitherman-appointed-deputy-premier//|title=George Smitherman Appointed Deputy Premier|newspaper=news.ontario.ca|date=September 21, 2006 |access-date=October 23, 2024}}
The year ended with the number of cabinet members at 26, while the number of portfolios stood at 27 (including the Premiership).
=2007=
==New Portfolios==
McGuinty created two new portfolios over the course of the year:
- Ministry of Revenue was created February 21, 2007, to help implement a harmonized corporate tax collection system with the federal government. Newly appointed cabinet minister Michael Chan was brought into the ministry to helm this portfolio.{{cite news|url=https://news.ontario.ca/en/release/4312/michael-chan-becomes-ontarios-minister-of-revenue//|title=Michael Chan Becomes Ontario's Minister Of Revenue|newspaper=news.ontario.ca|date=February 21, 2007 |access-date=October 24, 2024}}
- Ministry of Aboriginal Affairs was created June 21, 2007, in response to recommendations by the Ipperwash Inquiry.{{cite news|url=https://www.ontario.ca/document/spirit-reconciliation-ministry-indigenous-relations-and-reconciliation-first-10-years/new-beginning-ministry-aboriginal-affairs#:~:text=The%20Ministry%20of%20Aboriginal%20Affairs%20was%20created%20on%20June%2021,had%20a%20Native%20Affairs%20Secretariat.//|title=A new beginning: The Ministry of Aboriginal Affairs|website=news.ontario.ca|date=June 21, 2007 |access-date=October 24, 2024}}
Thus the number of cabinet members swelled to 27, even as the number of portfolios (including the Premiership) increased to 29.
==Post Election Shuffle==
An extensive cabinet shuffle occurred October 30, a few weeks after the 2007 Ontario general election,{{cite news|url=https://www.theglobeandmail.com/news/national/shuffle-sees-two-rookie-mpps-join-cabinet/article1085693//|title=Shuffle sees two rookie MPPs join cabinet|newspaper=The Globe and Mail|date=October 30, 2007 |access-date=October 24, 2024}} in which the Liberals secured another majority with nearly identical results to the last election, winning 71 out of 107 seats.{{cite news|url=https://results.elections.on.ca/en/graphics-charts//|title=Graphics and Charts|website=Elections Ontario|date=October 11, 2007 |access-date=October 24, 2024}}
Greg Sorbara, who was re-elected to parliament, declined to continue to serve as Minister of Finance.{{cite news|url=https://www.yorkregion.com/news/sorbara-resigns-from-cabinet/article_e6e1b274-c107-561e-ae03-a48206f286cc.html//|title=Sorbara resigns from cabinet|website=yorkregion.com|date=October 26, 2007 |access-date=October 24, 2024}}
Ten newly appointed cabinet ministers were brought in, including two newly elected MPPs. Only seven established cabinet ministers retained their portfolios and were not shuffled. All told, eleven established cabinet ministers changed portfolios.
There were no new ministries created in this shuffle, but one instance of ministerial reorganization:
- Ministry of Government Services was reorganized into "Ministry of Government and Consumer Services".
Thus, with this shuffle, the ministry expanded to 28 cabinet members, even as the number of ministries remained steady at 29.
=2008=
On June 20, 2008, in the wake of a controversy surrounding a wave of C. diff infections at Ontario hospitals, George Smitherman was replaced as Minister Health and Long Term Care by Minister of Public Infrastructure Renewal David Caplan.{{cite news|url=https://www.thespec.com/news/smitherman-sidesteps-c-diff-in-cabinet-shuffle/article_e74d2222-d9bc-5f73-8b28-50ea257ecd03.html//|title=Smitherman sidesteps C. diff in cabinet shuffle|newspaper=Hamilton Spectator|date=June 20, 2008 |access-date=October 25, 2024}} A new portfolio would be created:
- Minister of Energy and Infrastructure, a "super-portfolio" combining two existing ministries.
A second small shuffle occurred September 18, 2008, when, in an effort to confront Ontario's sagging economy and shrinking manufacturing sector during the Great Recession{{cite news|url=https://toronto.citynews.ca/2008/09/18/mcguinty-shuffles-cabinet/amp/|title=McGuinty Shuffles Cabinet|website=toronto.citynews.ca|date=September 18, 2008 |access-date=October 25, 2024}} McGuinty reorganised several ministerial portfolios:
- Ministry of Economic Development and Trade was divided into two new ministries, the "Ministry of Economic Development", and the "Ministry of International Trade and Investment,".
- Ministry of Revenue was folded back into the Ministry of Finance.
Three other established cabinet ministers were involved in the September 18 shuffle. The year ended with the number of cabinet members and number of portfolios (including the Premiership) equal at 28, with Dalton McGuinty himself still covering two portfolios (Premier and Intergovernmental Affairs), while Gerry Phillips was minister without portfolio.
=2009=
==Bryant Departs==
Ambitious high-profile minister Michael Bryant was eased out of cabinet, surrendering first his position as House Leader to his deputy Monique Smith February 4, 2009, and later stepping down as Ministry of Economic Development on May 25. He would move on to become CEO of Invest Toronto, and his vacancy would be filled by McGuinty himself in the interim. It was reported that McGuinty felt that Bryant represented a challenge to his authority.{{cite news |first=Lee |last=Greenberg |title=Bryant Profile: Brilliant, ambitious politician often at odds with premier |newspaper=Ottawa Citizen |date=September 1, 2009 |url=https://ottawacitizen.com/business/Bryant+Profile+Brilliant+ambitious+politician+often+odds+with+premier/1951160/story.html}}
==Ministries Realigned==
On June 24, 2009, a minor shuffle involving six established cabinet ministers occurred.{{cite news|url=https://toronto.ctvnews.ca/mcguinty-says-cabinet-shuffle-all-about-economy-1.410771?cache=yes%253FclipId%253D373266%253FclipId%253D68597%253FautoPlay%253Dtrue%253Fot%253DAjaxLayout%253Fot%253DAjaxLayout%253Fot%253DAjaxLayout%253Fot%253DAjaxLayout%253FclipId%253D89619%3FautoPlay%3Dtrue|title=McGuinty says cabinet shuffle all about economy|website=toronto.ctvnews.ca|date=June 24, 2009|access-date=October 26, 2024}} In regards to two of the changes (among the several implemented this day), this shuffle could be considered largely an undoing of changes made in September of the previous year:
- Ministry of Economic Development and Trade was recreated, as the experiment of a separate "Ministry of Trade" and "Ministry of Economic Development" was terminated, and the ministries were reunited.
- Minister of Revenue was recreated, as it was divided from Finance.
There were also two other instances of ministerial portfolio reorganisation:
- the responsibility for forestry was moved from Ministry of Natural Resources to the renamed Ministry of Northern Development, Mines and Forestry
- the responsibility for small businesses was stripped away from the Ministry of Consumer Services and the ministry was downsized.
While several ministries thus took on new looks, there would be no new faces in the ministry.
==Caplan, Smitherman Depart==
The embattled Ministry of Health and Long term Care faced a serious scandal for the second year in a row.{{cite news|url=https://toronto.ctvnews.ca/mcguinty-says-gov-t-takes-responsibility-for-ehealth-1.441345?cache=yesclipId104062|title=McGuinty says gov't takes responsibility for eHealth|website=toronto.ctvnews.ca|date=October 7, 2009|access-date=October 26, 2024}}
Former Minister of Health George Smitherman was also not long for the ministry. On November 9, he resigned from his post as Minister of Energy and Infrastructure and Deputy Premier of Ontario to run for mayor of Toronto.{{cite news|url=https://www.cbc.ca/news/canada/toronto/smitherman-denies-ehealth-influenced-mayoral-run-1.797081|title=Smitherman denies eHealth influenced mayoral run|website=cbc.ca|date=November 7, 2009|access-date=October 26, 2024}}
The number of cabinet members at the end of the year sat at 26, while the number of portfolios (including the Premiership) was steady at 28.
=2010=
==Second Midterm shuffle, Part One==
Days before the big mid-term cabinet shuffle January 18, 2010,{{cite news|url=https://www.thestar.com/news/canada/mcguinty-shuffles-cabinet/article_ac4b5164-7346-5789-b2aa-6ebcc965faf4.html|title=McGuinty shuffles cabinet|newspaper=Toronto Star|date=January 18, 2010|access-date=October 27, 2024}} Jim Watson resigned from his post as Minister of Municipal Affairs and Housing to run for mayor of Ottawa. He became the second cabinet member to resign to pursue the mayoralty of a major Ontario city; unlike Smitherman, Watson would be successful and was elected mayor of Ottawa later in the year.
There was one instance of ministerial portfolio reorganisation:
- Ministry of Tourism and Culture, created by combining Ministry of Tourism and Ministry of Culture.
The number of cabinet members remained steady at 26, while the number of portfolios (including the Premiership) fell to 27.
==Second Midterm shuffle, Part Two==
On August 18, the second extensive shuffle of the year occurred; such sweeping changes occurring so close together is unusual, and indicated that the McGuinty ministry was struggling.{{cite news|url=https://www.thestar.com/news/canada/mcguinty-shuffles-cabinet/article_ac4b5164-7346-5789-b2aa-6ebcc965faf4.html|title=McGuinty shuffles cabinet|newspaper=Toronto Star|date=August 18, 2010|access-date=October 27, 2024}}
There were two instances of ministerial portfolio reorganisation:
- Ministry of Energy and Ministry of Infrastructure were created by the division of the "Ministry of Energy and Infrastructure" into two new ministries.
- Ministry of Health Promotion was renamed "Ministry of Health Promotion and Sport.
There would not be any instance of a cabinet member stepping down in this shuffle. In the end, both the number of cabinet members and the number of portfolios (including the Premiership) swelled to 28.
The final newly appointed cabinet minister to join the McGuinty ministry was Charles Sousa, brought on December 7 to replace Peter Fonseca at Ministry of Labour, who resigned{{cite news|url=https://news.ontario.ca/en/release/15972/premier-announces-new-minister-of-labour|title=Premier Announces New Minister of Labour|website=news.ontario.ca|access-date=October 28, 2024}}
=2011=
==Post Election Shuffle==
The 2011 Ontario general election resulted in the loss of 17 Liberal seats, leaving McGuinty one seat shy of a majority in Parliament.
Seven vacancies opened up in the McGuinty cabinet:{{cite news|url=https://toronto.ctvnews.ca/mcguinty-reveals-slimmed-down-cabinet-after-shuffle-1.713445?cache=gzmrjlzmpygo%3FclipId%3D1920563|title=McGuinty reveals slimmed down cabinet after shuffle
|website=toronto.ctvnews.ca|access-date=October 28, 2024}}
Six of the seven vacancies were filled thusly: the number of established cabinet ministers holding multiple portfolios increased from one to three, and three ministries ceased to exist:
- Ministry of Revenue was again returned to Ministry of Finance (Ontario).
- Ministry of Research and Innovation was absorbed by Ministry of Economic Development and Trade to become Ministry of Economic Development and Innovation.
- Ministry of Health Promotion and Sport was eliminated.
Thus the cabinet shrunk to 22, smaller than it had been at its inception in 2003, when it had 23 cabinet members. There were 25 portfolios (including the Premiership).
=2012=
Dalton McGuinty announced his retirement as Premier October 15, pending the election of a new Liberal Party leader.{{cite news|url=https://www.cbc.ca/news/canada/toronto/ontario-s-mcguinty-surprises-with-resignation-prorogation-1.1156014|title=Ontario's McGuinty surprises with resignation, prorogation|website=cbc.ca|access-date=October 28, 2024}}
Wynne succeeded to the Premiership February 11, 2013, and thus the McGuinty ministry came to a close.
Summary
46 different people served as cabinet members in the McGuinty ministry.
Sixteen women served, although never more than eleven at any given time. McGuinty began with only five women in his cabinet, and all of them in minor portfolios, whereas his predecessor (Premier Ernie Eves) had six women in his cabinet, including his Minister of Finance (Janet Ecker) and his and Deputy Premier (Elizabeth Witmer). However, in McGuinty's ministry, several women eventually achieved positions from which they exercised significant influence, including Deb Matthews as Minister of Health and Long-Term Care from October 7, 2009 to February 11, 2013, Sandra Pupatello as Minister of Economic Development (or related portfolios) from September 18, 2006 to October 20, 2011, and of course Kathleen Wynne, as Minister of Education from September 18, 2006 to January 18, 2010.
Trivia
Madeleine Meilleur's last name is French for "best;" Margarett Best's last name is English for "meilleur."
Meilleur was "Minister Responsible for Francophone Affairs" from October 23, 2003 to February 11, 2013.
David Caplan, in taking over as Minister of Health on June 20, 2008, holds the same position his mother Elinor held under Premier David Peterson 1987-1990.{{cite news|url=https://www.tvo.org/article/like-mother-like-son//|title=Like Mother, Like Son|website=tvo.org|date=June 20, 2008 |access-date=October 25, 2024}}
