Tree Canada



May 22, 2019 (Ottawa, ON) – The Board of Tree Canada is pleased to announce the appointment of Danielle St-Aubin as its Chief Executive Officer, effective July 2, 2019. Ms. St-Aubin has worked in the not-for-profit sector for more than 15 years and has acquired a deep knowledge of the development and implementation of a broad range of strategies including communications and marketing, fundraising, sponsorship, and events. In her most recent role as Vice-President of Communications and Marketing at Trans Canada Trail, she was responsible for raising the profile and increasing the reach of the organization. Before that, she served as Vice-President, Donor Relations at The Ottawa Hospital Foundation. She began her career as Publicist at United Way Ottawa before moving on to the Canadian Wildlife Federation, where she managed the rebrand and re-launch of the iconic Hinterland Who’s Who (HWW) program. She has an MBA from the Telfer School of Business.

Michael Rosen will be retiring from Tree Canada as of March 31, 2020 but will spend the remainder of his tenure as President assisting with the smooth transition of leadership as well as supporting key development and other initiatives of importance to this growing and increasingly active organization.

“Michael has shown remarkable leadership of Tree Canada over his 18 years serving the organization,” said Board Chair, David Domke. “He successfully transitioned a government-funded organization to a fully, privately-funded, self-sustaining non-profit, something that has rarely, if ever, been accomplished before. With Michael at the helm, Tree Canada has become Canada’s leading urban forest organization, planting over 82 million trees in school grounds and urban centers, and re-treeing neighbourhoods after natural disasters. He oversaw the development of Tree Canada’s first carbon offset protocol, and helped establish the Canadian Urban Forest Network, a network of 900+ urban forestry professionals. He worked with the University of British Columbia to establish Canada’s first Bachelor of Urban Forestry program and became an Adjunct Professor of the university. He was instrumental in having Parliament proclaim Canada’s annual National Tree Day.”

Danielle is excited to join the team at Tree Canada by building on its solid foundation, growing the Tree Canada brand over the next few years with existing initiatives, programs and partners, while seeking out new opportunities to further strengthen its leadership position in urban forestry. Future growth plans include the expansion of Tree Canada’s role in facilitating urban forest planning and programming, continuing to educate an increasingly urban society on the benefits and joys that trees provide, and to continue to be the “go-to” organization for communities whose urban forests have been impacted by such disasters as fires, insects and extreme weather – continuing its mandate by “growing better places to live”.
