Key Points
Coon led the New Brunswick Greens for 14 years, building the party from zero seats to three.
Party's popular vote grew from under 7 percent in 2014 to peak of 15 percent in 2020.
New leader will be chosen by year-end 2026 with two years to prepare for 2028 election.
Coon will remain as MLA for Fredericton Lincoln after stepping down as party leader.
David Coon announced Thursday he will step down as leader of the New Brunswick Green Party after 14 years at the helm. The 69-year-old environmentalist will remain as MLA for Fredericton Lincoln and stay in the leadership role until the party chooses a successor by year-end. Coon built the Greens from zero seats to a peak of three, though the party now holds two seats after losing ground in the 2024 election.
From Zero Seats to Historic Breakthrough
Coon became leader in September 2012 without a seat in the legislature. In 2014, he won election in Fredericton South, becoming the first Green member elected to a provincial legislature in the Maritimes and just the second in Canada. The party grew to three seats in 2020 with Megan Mitton and Kevin Arseneau, who was the first Green francophone elected in North America.
Under Coon’s leadership, the party’s popular vote share grew from less than 7 percent in 2014 to a peak of about 15 percent in 2020. The party’s support fell to less than 14 percent in 2024, when the Liberals won a majority government and the Greens lost Arseneau’s seat.
Why Coon Is Stepping Down Now
Coon said he wants the new leader to have a runway of two years to introduce themselves to New Brunswickers before the 2028 election. The party will announce details of a leadership convention in the coming weeks. Coon expects the selection process to finish by year-end.
“People respond to parties that give a damn,” Coon said at his announcement Thursday. He described his tenure as merely the “launch” of the New Brunswick Greens and predicted the party will eventually form a government in the province.
Cross-Party Respect for Coon’s Record
MLAs from all parties applauded Coon in the legislature Thursday afternoon. Local Government Minister Aaron Kennedy said Coon “has certainly served his constituents and the people of New Brunswick well for a long time.” Progressive Conservative Opposition Leader Glen Savoie, who disagreed with Coon often, said the Green leader “has always had the best interest of New Brunswickers at heart.”
Megan Mitton, the party’s only other elected member, attended Coon’s announcement and paid tribute to his achievements. She said it was too early to comment on whether she would run for the leadership but acknowledged she was thinking about it. Federal Green Party Leader Elizabeth May credited Coon for growing the party and said she is “eternally grateful” for his leadership.
What Comes Next
Coon, a trained biologist and former executive director of the Conservation Council of New Brunswick, championed renewable energy development and pushed for stronger clean water laws during his tenure. He raised the profile of environmental issues in the legislature and brought what observers describe as strong ethics to provincial politics.
The party will now seek a new leader to rebuild support ahead of 2028. The Liberals currently hold a majority in the legislature, with the Progressive Conservatives as the main opposition.
Final Thoughts
Coon’s departure marks a transition for New Brunswick’s Greens after a decade of growth and recent decline. The party must now find a leader who can rebuild momentum before the 2028 election.
