Kris Rivard
Born, raised, and educated in Northern Ontario, I am bilingual in French and English. I obtained a BA in Geography from Laurentian University and a post graduate certificate from Canadore College in Environmental Studies.
Growing up in Northern Ontario offered me many opportunities to develop my love of the outdoors and remain active. I continue to camp, canoe and hike as well as participate in men’s league hockey and soccer. I love being out on the water fishing or outside, woodworking and gardening.
Employed as a Sewage System Inspector for the North Bay-Mattawa Conservation Authority, I oversee new and existing residential, commercial, and industrial development in the Nipissing District. Also had the unique opportunity to work with the Algonquin Park Cottage Lot Liaison team on their recently renewed lease policy with cottagers in Algonquin Park.
I have been a Green Party of Ontario member since 2018; running as a candidate in Nipissing in the 2018 Election. Then most recently as a candidate in Timiskaming-Cochrane in 2022, where we founded a Constituency Association in the electoral district.
I ran successfully in the most recent Municipal Election. And am now a Councillor representing Ward 1 in the Municipality of West Nipissing, having garnered over 80% of the vote to become the youngest elected official in our Municipality’s history.
Arleigh Luckett
Arleigh Luckett offers a wealth of relevant experience to Provincial Council. For the past 4 ½ years she was President of the Parry Sound-Muskoka Constituency Association leading the team that laid the ground work for Matt Richter’s second place finish in 2022.
In her 20 year career working for provincially funded social service agencies she gained insight from many points of view on both sides of the bargaining table first as front line staff and president of an OPSEU local and later as Manager of Information Systems and Human Resources.
As a volunteer Arleigh has led her local ratepayers association and several other community organizations. Currently, she co-leads Pflag Canada’s Muskoka Chapter. She is an active member of Climate Action Muskoka and a gardener for Gravenhurst Against Poverty.
Arleigh is a dedicated environmentalist. She moved to Muskoka over 50 years ago as part of the “back to the land” movement. She and her partner built their own home – a geodesic dome.

Since becoming a member in 2019, Kyle has twice represented the Ontario Greens on the ballot in Halton Region, working hard to get the message out at the doorsteps. As someone who works with data, Kyle understands the insights and advantage a good data ground game can give to even the smallest of campaigns.

Southwestern Region
Tyrone Russell
I’m originally from Mississauga and moved to Hamilton to study English and Philosophy at McMaster University. Afterwards, I moved to Japan to teach English and became very interested in public transit, having seen how it was implemented there in comparison to Canada. Upon my return, I was involved in the public consultation process for the Hurontario Light Rail Transit line linking Brampton and Mississauga while working in my second career of supply chain logistics. Shortly thereafter, I decided to move to Ottawa to get my B.Ed and following graduation I worked in the not-for-profit education sector in Scarborough. Through that work I was connected to a community organization in Kitchener focused on underserved youth and moved here to pursue that opportunity. From there I transitioned into public school education with the Waterloo Region District School Board and now work as a K-8 teacher. I am a former executive member of my local teacher union with a focus on political action and public relations.
I officially joined the Green Party after my district elected Ontario’s first Green MP and have since become vice president of my constituency association and an executive member of our electoral district association. I would like to join the provincial executive because I want to continue to do my part to create a greener Ontario through the political process. The green causes that matter most to me are public transit, electric vehicles, urban green spaces, indigenous issues, and electoral reform.

Toronto Region

I have been married for almost 13 years and am a parent to an adult son. I have been a member of the Green Party of Ontario since 2009.

Gianne Broughton
I am a newcomer to the Toronto region, having served the GPO on Constituency Associations as CFO or President in Ottawa (2008 to 2015) and Peterborough (2016 to 2023). When I moved to Beaches East York in 2024, I stepped forward to be Interim President and Campaign Manager so that we could be prepared for the snap election. I am focussed on finding low-cost, high-impact strategies to help the CAs who are typically running small campaigns to stay viable and grow. I have been the candidate in two “small campaigns” as well: Peterborough for GPO in 2018, and Scarborough-Woburn for GPC in 2025. In all of our campaigns, we need not only to Get Out the Vote, but also to Inspire.
I am a semi-retired grandmother with a masters’ degree in International Rural Planning and Development from the University of Guelph, and more than 20 years experience in peace and community development in Ontario and in countries recovering from war. I also teach French.
Pendant ma service avec le conseil provincial, je vise à épauler le communauté francophone du Parti Vert d’Ontario.
I am delighted to have the opportunity to collaborate with the talented, experienced, dedicated people on the GPO Provincial Executive. Together, I believe we can inspire Ontarians to believe in a low-carbon, healthy, affordable future. And to vote for it.
Eastern Region
Michelle Petersen
I grew up in Orléans and currently live there with my son. As a proud Franco-Ontarian, I am committed to maintaining and improving French language services in the province. It was my advocacy for the bilingualization of the GPO website that led to me being recruited to run in the last provincial election. During the 2022 election campaign, I initiated weekly meetings for all the candidates in the Eastern Region. While the original goal was to support one another in preparing for upcoming debates and public engagements, the group became the launching pad for extensive cross-regional collaboration.
My professional background is in the area of mental health and gender-based violence. I am a member of the College of Registered Psychotherapist of Ontario as Registered Psychotherapist (Inactive). My personal experience as a survivor as well as my career, have provided me with an in depth understanding of mental health and trauma. In the fall of 2022, I accepted a 1-year mandate as the Interim Director General at Action ontarienne contre la violence faite aux femmes, the provincial coalition for francophone and feminist services that support victims and survivors of gender-based violence. In this role, I have been leading 14 member organizations to develop systems and mechanisms to increase their collaboration through the sharing of knowledge and resources.
Largely influenced by my background in therapy and social services, I take a collaborative approach to leadership. My intersectional feminist analysis leads me to question the status quo and to seek out those people who are not yet sufficiently represented in decision making. My exceptional listening and observation skills allow me to identify people’s needs as well as their apprehension, which is essential to managing interpersonal dynamics or implementing change within a group or organization.
I would like to represent the Eastern Region on the Provincial Executive. I see this as an opportunity to continue building upon the work I have done in three key areas :
- cross-regional collaboration and sharing of resources,
- understanding and promotion of the francophonie,
- equity, diversity and inclusion.
I am committed to seeing Ontario voters recognize the dynamic, honest and engaging way we do politics. I would like to be part of a team which is striving to build our capacity so that we may offer Ontarians healthy, connected and sustainable communities.
Simon Beckett
Simon is a small business owner, artist, and long-time Green organizer. He ran as a Green Party candidate in the 2025 Ontario election and currently serves as President of the Ottawa Centre Constituency Association.
In these roles, Simon has built strong connections with members, organized local campaigns, and strengthened the presence of Greens in Ottawa. His experience leading teams, managing budgets, and fostering community engagement has given him the skills to support the party’s growth across the province.
Simon combines his experience as an entrepreneur with creative vision, and is committed to strengthening the Green Party of Ontario by ensuring Ottawa and Eastern Ontario voices are heard, represented, and empowered as we continue to grow the party.
Young Greens
Courtney Martin
My name is Courtney Martin. I was born and raised in Toronto. I hold a Bachelor of Social Sciences from the University of Ottawa, specializing in Political Science with a minor in Psychology, and I am currently completing my paralegal studies at Humber Polytechnic.
I have volunteered with the Green Party of Ontario and am deeply committed to justice, accountability, and equitable governance. I am motivated by the belief that meaningful change starts with youth, and that we have a responsibility to work toward the future we want to see.
I am honoured to serve as Youth Co-Chair and look forward to advocating for youth voices and advancing Green values across Ontario.
Jaycob Jacques
My name is Jaycob Jacques, and I am currently a student at the University of Ottawa. I find joy in simple pleasures such as crochet, reading, volunteer work, and gardening. Having lived in social housing, I have experienced the strong sense of community that planned housing can foster, solidifying my belief in the importance of ensuring affordable housing.
Growing up in a francophone family in Sudbury, Ontario, I learned the importance of accessible French education and services, through my school and work with ACFO. I was deeply influenced by my mother, a career ICU nurse, and my grandmother, a primary school teacher, who both exemplified humility and community care. They sparked my interest in the caregiving profession and inspired me to support and advocate for these dedicated professionals, who are key to equitable and accessible health services.
My hometown, once called the “moonscape” due to its barren and empty landscapes caused by years of acid rain and environmental mismanagement, is now a basin of environmental wisdom. Years of reforestation and efforts to promote biodiversity have transformed it into a thriving example of environmental recovery, from which I draw my green roots.
