Peter Charles Tabuns MPP (born October 3, 1951) is a Canadian politician who served as the interim leader of the Ontario New Democratic Party and the leader of the Official Opposition from 2022 to 2023. He is a member of the Legislative Assembly of Ontario, first elected in a 2006 by-election to represent the riding of Toronto—Danforth.

Key Information

In 2009, he entered the party leadership convention but lost to Andrea Horwath. Following Horwath's resignation as leader after the 2022 Ontario general election, the Ontario New Democratic Party caucus unanimously recommended Tabuns' selection as the Ontario NDP's interim leader. His appointment was confirmed by the party's provincial council on June 28, 2022.[1][2] He served until the election of his successor, Marit Stiles, following the leadership election.

Following the 2025 Ontario general election (February 27, 2025), Peter Tabuns was appointed the Official Opposition Critic for Emergency Preparedness and Response, and for Environment, Conservation, and Parks.[3]

Background

[edit]

Tabuns was born in London, Ontario, to Anton Tabuns (Latvian: Antons Tabūns), an auto mechanic, and his wife Sarah, who was born and raised in Liverpool, England. Anton was born and raised in Latvia, though he managed to leave his homeland after the Soviet occupation and immigrate to England. While working on a farm, fixing equipment, he met Sarah, and soon after marrying, the couple immigrated to Canada. Soon after, the family found residence with another recent immigrant. In addition to Peter, Anton and Sarah have two other children, Frank and Anna.[4]

Tabuns attended York University, where he studied political science and was actively involved in York's student council. Tabuns was also president of Citizens for a Safe Environment, a Riverdale environmental group that lobbied the city to end garbage incineration at the Commissioners Street plant in the Port Lands. He became managing director of a housing co-op on Oak Street, and was also vice-chair of the Co-operative Housing Federation of Toronto.[5]

He lives with Shawn Kerwin, who is a theatre designer and professor at York University. They have a son, Anton, from Tabuns' previous relationship.

Municipal politics

[edit]

Tabuns was city councillor for Ward 8 - Riverdale - of the former City of Toronto from 1990 to 1997, representing part of the Toronto-Danforth riding he now represents provincially. He was a member of the Board of Health for seven years, and was chair from 1993 to 1997. In 1995 he moved to ban smoking in shopping mall food courts. A year later the city extended the ban to include bars and restaurants.[6][7]

In 1996, he supported a boycott of Harvey's restaurants because its parent company Cara Operations had donated money to the Progressive Conservative Party for the previous three years. The Board of Health initially passed the motion 7-6 but later rescinded it following a storm of protest. Tabuns was unrepentant and said that corporations must be held accountable for supporting Ontario Premier Mike Harris. Tabuns said, "What Mike Harris has done is put greased skids under the economy of this city and pushed it downhill."[8]

In 1997 the amalgamation of Metropolitan Toronto reduced the number of councillor positions. Tabuns was forced to compete with fellow NDP councillors Pam McConnell (who had previously represented Ward 7, adjacent to Tabuns' Ward 8) and Jack Layton (who had held a seat on Metro Council representing the same area as Wards 7 and 8) for one of two council positions returned by the east-end ward. A phantom candidate named "Larry Tabin" also entered the election. It has been alleged that Tabin was enlisted as a candidate by bar and restaurant owners seeking to defeat Tabuns over his anti-smoking initiative; despite his presence on the ballot, Tabin did not actually conduct any visible campaign. In the confusion, Tabin was able to draw enough votes away from Peter Tabuns to cost Tabuns the election.[9] Tabuns came in third, with about 200 fewer votes than McConnell.[10]

Greenpeace

[edit]

From 1999 to 2004, Tabuns was executive director of Greenpeace Canada. Under Tabuns' leadership, the organization advocated for environmental protection, including the adoption of the Kyoto Protocol. Tabuns also served as special advisor on climate change to Jack Layton from 2004 to 2005.

Tabuns was criticized by some members of Office and Professional Employees International Union (OPEIU) local 343 (now Canadian Office and Professional Employees Union 343) in 2002, when Greenpeace terminated its door-to-door fundraising efforts and transferred foot canvassers to telephone fundraising. No layoffs occurred; however, several workers disputed Greenpeace's assertions that the new positions were of "comparable salary and benefits", and held an information picket outside Greenpeace offices.[11] According to the union, the "circumstances surrounding the closure of the door canvass were amicably resolved".[12]

Federal politics

[edit]

Tabuns ran as the NDP candidate in the riding of Beaches—East York during the 2004 federal election. He lost the election to Liberal incumbent Maria Minna by 7,738 votes.[13]

Provincial politics

[edit]

On February 15, 2006, the Toronto—Danforth NDP riding association nominated Tabuns as the party's candidate in the provincial by-election, to fill the vacancy caused by the resignation of former NDP Member of Provincial Parliament Marilyn Churley. Churley resigned her provincial seat in order to run in the 2006 federal election as the NDP candidate for Beaches-East York.

Tabuns' opponents in the election were former broadcaster and Liberal candidate Ben Chin, Progressive Conservative candidate Georgina Blanas and Green Party candidate Paul Charbonneau. On March 30, 2006, Tabuns won the by-election with 47.8% support from voters.[14]

Upon being sworn in as an MPP, NDP Leader Howard Hampton reorganized his shadow cabinet and gave the rookie member a long list of portfolios, including Transportation, Environment, Public Infrastructure Renewal, Greater Toronto Area, Culture, Tourism and Recreation, Citizenship and Immigration, and Multicultural Affairs.[15]

In October 2006, Tabuns was voted Best MPP by Now Magazine readers, for his positions on climate change, the Portlands Energy Centre, and early childhood learning centres in his constituency.[16] Tabuns has also been known for his stance on same-sex parental rights, anti-toxics legislation and recognition of foreign credentials. In the same month, Tabuns was recognized for tabling a motion to recognize June 22, 2006 as Chinese Canadian Head Tax Redress Day.[17]

Tabuns was re-elected in the 2007, 2011, 2014, 2018, 2022, and 2025 provincial elections.[18][19][20]

He served as the party's interim leader,[2] after previously serving as the party's critic on energy and climate change[21] and before that critic for Education and Energy issues.[22] After the election of Marit Stiles, he returned to his role as critic on energy and climate change.[23]

Following the resignation of party leader Howard Hampton in June 2008, Peter Tabuns was mentioned in the press as a likely candidate in the emerging campaign for the leadership.[24] On October 27, 2008, Tabuns officially launched his campaign for the leadership.[25] The party's leadership convention was held in March 2009. Tabuns lost to Andrea Horwath by a margin of 60% to 40% on the third ballot following the defeat of contenders Michael Prue and Gilles Bisson in earlier rounds.

The decision highlighted tensions between environmental advocacy groups and regulatory oversight on the distinction between charitable and political expenditures. In 2002, Tabuns represented Greenpeace Canada in promoting a report co-authored with other groups, which called for stricter vehicle emissions standards to reduce smog and improve public health outcomes in urban areas like Toronto.

Tabuns opposes investments in pipelines, describing them as financially unwise due to their impending obsolescence amid goals and potential stranded assets. He has rallied opposition to specific projects, such as one in South Riverdale, and called for ending subsidies that burden gas customers with over $1 billion in costs over four years. As NDP Energy and critic, he has accused the governing Conservatives of favoring the gas sector at the expense of . On , Tabuns has expressed longstanding skepticism, co-organizing anti-nuclear events and urging halts to new builds during his early legislative career. While the NDP has historically opposed nuclear expansion, Tabuns has recently emphasized the need for careful decision-making on refurbishments, such as at Pickering, and noted the party's evolving approach to align with workers' interests ahead of elections. In climate policy, Tabuns views the issue as an escalating crisis requiring immediate measures. He introduced the Climate Adaptation and Resilience Act in May 2024 to bolster provincial defenses against environmental disasters, including mandates for risk assessments and infrastructure upgrades. Tabuns has also advocated for workplace heat protections amid rising temperatures and warned that is off-track for its 2030 emissions targets, contradicting government claims. Additionally, he tabled the Affordable Energy Act in March 2024 to cap rate increases and promote efficiency, aiming to balance affordability with reliability during the transition to low-carbon systems.

Economic and social stances

Tabuns has advocated for policies aimed at reducing costs for households, introducing the Affordable Home Heating Act in 2024 to enhance reliability and affordability of supplies amid rising bills. He has criticized government legislation that he argues increases expenses without sufficient , such as opposing aspects of Conservative-backed bills in May 2024 that he claimed would raise rates. On labor issues, Tabuns has opposed wage restraint measures, including Bill 124 passed in 2019, which capped wage increases at 1% annually; he supported its invalidation by in November 2022 as a win for workers facing exceeding 7% that year, arguing it exacerbated shortages in sectors like . In , Tabuns has called for expanded funding for social assistance programs, highlighting in December 2023 that the Ford government underspent by hundreds of millions on supports during a cost-of-living crisis, leaving vulnerable populations without adequate aid. He has pushed against healthcare , warning in public forums that shifting services to private entities would drain personnel from public hospitals, contributing to wait times and access issues. Tabuns supports initiatives to address housing affordability, stating in February 2018 a commitment to bolster requirements for new developments and allocate funds to repair aging social housing stock, aiming to provide stable options for low-income families. In March 2023 budget advocacy, he urged immediate government action to end through targeted investments rather than deferring to market-driven solutions.

Controversies and criticisms

Legislative conduct issues

On November 2, 2022, during debate in the Ontario Legislative Assembly on Bill 28, the Keeping Students in Class Act, 2022—legislation aimed at ending a strike by 55,000 education support workers represented by the Canadian Union of Public Employees (CUPE)—interim (NDP) leader Peter Tabuns accused and his ministers of "lying" about the bill's impact on the education system. The accusation violated Standing Order 23(f), which prohibits imputing false statements to members without evidence, prompting Speaker Ted Arnott to repeatedly ask Tabuns to withdraw the remark. Tabuns refused, leading to him being named by the Speaker and ordered to leave the chamber for the remainder of the day's sitting, a standard disciplinary measure for non-compliance. The incident escalated when 15 other NDP MPPs, protesting the government's use of the notwithstanding clause to override rights in the bill, refused to cease their outbursts and were similarly named and ejected, marking one of the largest mass ejections in recent legislative history. Tabuns defended his stance outside the , framing it as a necessary stand against perceived government deception during the labor dispute, which had disrupted schooling for over 1.7 million students. No formal investigation followed, as the matter was resolved under routine , though critics from the Progressive Conservative government highlighted it as disruptive to legislative proceedings amid the ongoing crisis. The bill passed later that day but was repealed in February 2023 after CUPE members ratified a new . Critics of Tabuns' energy policies have focused on his longstanding opposition to nuclear power, which he has advocated phasing out in favor of renewables, arguing it poses safety risks and generates problematic waste. This stance, rooted in environmental activism, has drawn rebukes for disregarding nuclear's role as a reliable, low-emission baseload source that supplies approximately 60% of 's , enabling stable grid operation without the intermittency challenges of and solar. Empirical assessments indicate that anti-nuclear policies contribute to higher energy costs and supply vulnerabilities, as seen in 's past reliance on expensive and delayed alternatives after canceling gas plants amid NDP-influenced opposition. The NDP's recent shift toward accepting nuclear refurbishments, announced in 2025, underscores critiques that prior rejection ignored economic realities and labor interests, prompting internal party reevaluation ahead of elections. Tabuns' advocacy for stringent Greenbelt protections has been faulted for exacerbating Ontario's affordability by limiting developable land, thereby constraining supply in a province where median home prices exceeded $800,000 in 2023 amid chronic shortages. Opponents contend that his resistance to targeted openings or reforms, such as those proposed in Bill 23, prioritizes environmental preservation over pragmatic development, ignoring data showing restrictions as a primary driver of elevated costs— with starts lagging by over 100,000 units annually. This approach, critics argue, sustains , as evidenced by stalled projects and rising rents, where causal factors like land scarcity directly inflate prices without addressing root supply deficits. His push for expanded rent controls, including a 2017 private member's bill to eliminate exemptions for post-1991 units, has elicited economic critiques for distorting incentives and reducing rental stock. Economists and property sector analysts assert that such measures discourage new construction and maintenance investments, leading to deteriorated units and black-market rents, as observed in jurisdictions with broad controls where supply contracted by up to 15% post-implementation. While intended to shield tenants, the policy overlooks evidence that vacancy decontrol and market signals foster greater long-term availability, with Ontario's pre-1991 controlled units showing higher abandonment rates compared to unregulated markets.
