Allen Braude | Communications Manager

Allen loves sharing information. He also loves movies, music, running, riding his bike through the Greenbelt, and breathing the fresher air ever since Ontario shut down its coal plants. Allen’s interest in the environment led him to work for Greenpeace. He holds a degree in film studies from Simon Fraser University and has worked for a variety of film festivals, including the Toronto International Film Festival where he was co-director of learning. He was also Communications Manager at Rethink Breast Cancer where he helped produce documentaries that told the stories of young women facing breast cancer. Allen is excited to be working with Environmental Defence, where he can fuse his enthusiasm for environmental issues with his passion for sharing stories. Read Allen’s blogs here.

Ashley Wallis | Program Manager, Water @ashleyewallis

Ashley grew up on the shores of Lake Ontario. From a young age she was concerned with environmental issues – always pestering her friends to switch to reusable water bottles, take action against climate change, and consider alternative modes of transportation. While studying biology at Western University, Ashley realized her passion for sustainability could fuel her career. After completing a master’s in Environment and Sustainability, she spent several years working for Evergreen, connecting urban dwellers with nature through education and hands-on action. Motivated by what diverse stakeholders and communities can accomplish together, and a love for swim and surf, Ashley is thrilled to lead Environmental Defence’s efforts to safeguard Canada’s freshwater.

Barbara Hayes | Communications Manager

Barbara owes it all to Ranger Rick. The gift of a magazine subscription from her grandparents sparked a life-long passion for environmentalism, and a belief that we have both individual and collective power to protect the planet. That belief lead her to co-founding the Canadian Youth Climate Coalition, where she helped mobilize a strong youth voice around climate action. Since that time, she has worked with a variety of organizations, developing communications programs on issues as diverse as sexual and reproductive health, transportation, and electoral reform. She holds a Master’s in Public and International Affairs from the University of Ottawa, where she focused on public discourse around climate policy. She’s thrilled to join the team at Environmental Defence, where she returns to her roots pushing for federal action on climate change. When not at work, she can be found in roaming the hills of Gatineau on her bike, spoiling her two pet rabbits, or reading in a park.

Brett Tryon | Program Manager, Blue Flag

A child of the 80’s, Brett grew up when environmentalism was becoming a global phenomenon. Issues like acid rain and the hole in the ozone layer made a big impression on Brett. She knew her career would be connected to the environment. After graduating from ecosystem management at Fleming College, Brett worked abroad on bird conservation projects. Her first job in Toronto was as a canvasser for Environmental Defence. After a three year stint as Coordinator of the Tommy Thompson Park Bird Research Station, Brett returned to Environmental Defence to coordinate the Blue Flag program. Through her involvement with Blue Flag, Brett enjoys working with communities across Canada that are helping to restore shorelines and lake ecosystems, improve water quality, and raise awareness about the importance of clean water and beaches.

Calista Arasaratnam | Accountant

Calista brings significant experience from the financial and charitable sectors. She loves working at Environmental Defence because she believes deeply in its vision, and that we cannot live healthy lives without a healthy environment.

Casie McGonegal | Executive Assistant

Casie worked with the Ontario Federation of Indigenous Friendship Centres before joining the Environmental Defence team as the Executive Assistant. She cares about the environment and strongly believes that decisions we make today must take into account the impacts they will have seven generations from now. Casie believes everyone has a responsibility to protect Mother Earth. She is proud to be part of the team at Environmental Defence making positive changes to protect to our environment.

Corinne Berman | Development Director

Corinne possesses a unique background that encompasses the corporate, educational and non-profit sectors. She has an Honours and a Master of Business Administration from the University of Western Ontario (Ivey), and spent the first decade of her career focused on creating unique customer loyalty experiences at multi-national organizations. Her passion to protect the environment guided her journey, as she taught global economic issues and used her expertise to consult to the NGO world. During this time she introduced forward thinking concepts such as “natural capital,” which looks at the world’s natural resources as finite assets which need careful management. As the Director of Development at Environmental Defence, Corinne has found the perfect way to leverage her business skills to help protect our precious environment. When Corinne is not raising funds for EDC, she can be found baking – with chocolate of course – or puttering around her garden.

Dale Marshall | National Program Manager

Dale grew up in northeastern Quebec, roaming the boreal forest that began at his family’s backyard fence and, during the one month it was possible, splashing around the North Atlantic. While undertaking a mechanical engineering degree at McGill University, Dale discovered he was much more interested in the natural world and the systems needed to let it flourish than working on built environments. This realization led to a degree in environmental science, followed by a master’s degree in resource and environmental management at Simon Fraser University. For 15 years, Dale has worked on environmental protection, mostly related to energy and climate change. Policy research and advocacy in Vancouver and Ottawa was followed by two years in Cambodia to assist people and communities most vulnerable and impacted by climate inaction. As National Program Manager at Environmental Defence, Dale works to move Canada towards greater action and responsibility on climate change and towards clean, modern renewable energy technologies, while phasing out all fossil fuels such as oil, coal, and natural gas. Read Dale’s blogs here.

Daniella Niddery | Engagement Coordinator

Daniella’s love for the environment stems from her obsession with wildlife. Growing up on National Geographics, she quickly came to appreciate the complexities of nature, and the need to protect it for animals and future generations. After graduating from Brock University with a Bachelor of Arts (Honours) in Environmental Studies and Human Geography, she went on to pursue a master’s in Integrated Water Management at the University of Queensland in Brisbane, Australia. Returning to Canada, Daniella spent the summer volunteering for Environmental Defence. Recognized for her passion and commitment to Environmental Defence’s public outreach efforts, she soon became an outreach team member. A people-person who loves to share her learnings, she decided to complete a postgraduate certificate in public relations and communications at Humber College. Now, as Engagement Coordinator, Daniella helps to educate and engage the public on Environmental Defence’s campaigns. When not at work, she’s out walking her dog Lola, swimming at the cottage, or planning her next adventure. Read Daniella’s blogs here.

Deepa Ramesh | Development Coordinator

Deepa loves working with data, and has over 15 years of accounting and database management experience. Six years ago she decided to focus on finding purpose and meaning in her work, and, as a consequence, moved from the corporate to not-for-profit sector. Deepa has not looked back since, finding personal satisfaction in working for causes that are close to her heart. Having seen first-hand how air quality impacts one’s life, she feels fortunate to be part of Environmental Defence’s efforts for a cleaner, pollution-free environment for everyone.

Farrah Hasan | Development Manager, Major Donors

Farrah comes from a background in both the non-profit and corporate sectors. While having great experiences in both, she has come to realise that her true passion lies in non-profit organizations. At Environmental Defence she manages major and corporate donor relations, a role she enjoys because of the opportunities to directly build relationships with donors and corporations. Having completed her Honours BSc from UofT in Environmental Science, her interest and knowledge of the environment has always been strong and only continues to grow.

Jennifer Mayville | Communications Manager

Since she was a child, Jen has always had a passion for protecting the environment. It just seemed natural for her to work for Environmental Defence one day, combining her love of communications and taking care of the planet. Jen first started her career while in university, and since then has worked in the media and communications fields, including experience in print, television, and radio journalism. In 2005, she traveled to Rovaniemi, Finland to work in communications with the University of the Arctic – a NGO which focuses on post-secondary education in the Circumpolar North. After returning to Canada, she joined the Canadian Red Cross (2007) as a provincial communications co-ordinator. She became a communications manager at Environmental Defence in 2012. Jen has an Honors BA with Distinction in History and Media, Information and Technoculture and a MA in Journalism from the University of Western Ontario. Read Jennifer’s blogs here.

Jessie Farewell | Development Coordinator

Jessie has a background in English Lit from Memorial University. Her passion for reading and research then led her to the University of Western Ontario, where she completed a Master of Library and Information Science. Embarking on her career, she quickly realized that a paycheque at the end of the week was not the fulfillment she was seeking from her work. Coming from a place like Newfoundland and Labrador, with seemingly endless terrain to explore, she learned early on the importance of appreciating and preserving our environment, and knew that she wanted to play a role in its protection. Leaving her corporate gigs behind her, she has happily landed with the development team at Environmental Defence, with her role focused on grant writing and reporting.

Joshua Buck | Alberta Climate Program Manager

Joshua grew up in rural south western Ontario where he loved spending time at his grandfather’s dairy farm, driving tractors and playing in the bush. Travelling to Sudbury for his undergraduate degree he witnessed the power of action in remediating the city’s devastated landscape into a lush and beautiful one. Joshua then moved to Ottawa to pursue a Master’s degree in Public Ethics. While studying for this degree he took a six month break to work with HIV positive people in a township outside of Cape Town, South Africa. He moved to Edmonton in 2013 where he worked for Canada World Youth and volunteered with the Battle River Watershed Alliance. In 2015, he joined the Alberta government working first as constituency manager for MLA Thomas Dang, and then as ministerial assistant for the Ministry of Education. Joshua joins EDC hot off the heels of his time in government and is looking forward to how he can advance climate action in Alberta.

Keith Brooks | Programs Director


Keith was born in the ‘burbs just outside Toronto, but his passion for the environment was born in a canoe on the rivers and lakes of Northern Ontario. Keith pursued a Bachelor of Environmental Sciences from the University of Guelph and then worked for a number of years in the environmental consulting field, before enrolling at York University where he earned a Master of Environmental Studies. The move from scientist and consultant to advocate was provoked by the recognition that more science cannot solve the environmental challenge on its own. Our challenge lies not in knowing what must be done, but in doing it. We cannot choose between the environment and the economy. We can and must have both. It is this outlook which ultimately led Keith to his current role as the Program Director at Environmental Defence. Read Keith’s blogs here.

Kelsey Scarfone | Program Manager, Blue Flag

Kelsey was raised in Northern Ontario, where forests and lakes surrounded her every move. From an early age, her parents and grandparents demonstrated how to respect the natural environment and live off the land. This passion for nature followed her to post-secondary studies at Laurentian University’s School of the Environment. Her undergraduate degree sparked a passion to keep learning more, so she made the move to Ontario’s banana belt to complete a Master of Sustainability Science at Brock University. There she studied water stewardship in weak governance zones around the world. Kelsey is passionate about the human right to water and conserving our precious Canadian freshwater resources. She brings experience with the Ministry of Natural Resources & Forestry, and work with northern communities in water science education programs to Environmental Defence and to Blue Flag. She is proud to work for an organization that champions science and environmental sustainability. Read Kelsey’s blogs here.

Muhannad Malas | Program Manager, Toxics

Growing up in different parts of the world allowed Muhannad to learn at an early age about the intricate links between the environment, human health and equity. After completing a master’s degree in public health policy at the University of Toronto, Muhannad helped develop and implement chronic disease prevention policies and environmental health frameworks for municipal and provincial governments. With his passion for fostering a healthy and just environment, Muhannad is working towards the elimination of toxic chemicals as Environmental Defence’s Toxics Program Manager.

Patrick DeRochie | Program Manager, Climate & Energy @PatDeRocH

Patrick was born and raised in the Niagara Region and grew up enjoying its parks, forests, and beaches. Patrick’s love of nature led him to study the international security dimensions of climate change as a graduate student at the Norman Paterson School of International Affairs. Following a stint as a political staffer at Queen’s Park working on health and environmental issues, he moved into political organizing and government relations with a Canadian health care union. Patrick joined Environmental Defence in 2015, where he coordinated the Clean Economy Alliance, working to advance climate action policy in Ontario. As Climate & Energy Program Manager he led Environmental Defence’s campaign to stop the Energy East tar sands pipeline until the project’s cancellation in 2017, and works to accelerate climate action in Canada, eliminate fossil fuel subsidies, and align energy projects with climate policy. Patrick enjoys cycling, hockey, live music, and camping, and can be found nerding out in Toronto’s east end. Read Patrick’s blogs here.

Rachel Kitchin | Communications Manager

Rachel grew up surrounded by muddy dogs and muddier fields in the English countryside, but it was six months in urban China that taught her the real value of clean air and clear water. As a recent arrival in Canada, she has already fallen in love with Ontario’s beautiful lakes and wide open spaces. After completing an MA in International Politics at the University of London, she fell happily into a career in the non-profit sector, spending three years working on disability equality with the Guide Dogs for the Blind Association before making her move across the pond.

Sarah Buchanan | Program Manager, Clean Economy

Sarah began her environmental activism at age six, when she proudly began wearing a t-shirt with the word RECYCLE spelled out in silver sequins. Once the shirt disintegrated from overuse, she moved on to naturalizing her schoolyard, biking, hiking, camping, and learning about compost. In her professional life, Sarah has worked for the last 15 years in advocacy, media, and politics in both Ontario and British Columbia. She has worked for a City Councillor, managed programming at an independent radio station, led advocacy campaigns, and helped create a non-profit organization to empower young women in music. She was inspired to join Environmental Defence’s team through a desire to drive swift action on climate change, and now works as the Program Manager for the Clean Economy program in Ontario. Read Sarah’s blogs here.

Sarah Jamal | Program Coordinator, Toxics

Growing up in Hamilton, Sarah was always a short distance away from waterfalls, hiking trails, and farmers markets, feeding her passion for the environment and sustainable living. While studying International Development at the University of Waterloo and attending international climate negotiations, Sarah realized that she could turn her passion for the environment into a career. She had the opportunity to work in Vietnam in the sustainable agriculture and consulting field connecting people to the source of their food. After a year, she returned to Canada to work in the corporate social responsibility (CSR) sector for a Fortune 500 company. Excited to apply her learnings from abroad and in CSR, Sarah joined Environmental Defence first as a Communications Intern and now as a Program Coordinator for EDC’s Toxics Campaign. When not at work, you can find Sarah brewing a batch of kombucha, doing yoga, or making DIY health and beauty products! Read Sarah’s blogs here.

Susan Lloyd Swail | Senior Manager, Livable Communities

For over 20 years, Susan has been advocating for sustainable communities. Her career veered from the private sector to community advocate when she and a group of citizens won a fight to stop a ‘Big Pipe’ that would enable sprawl on the edge of the GTA. Following this victory, she was elected to Council in 2000, and served for one term. While on Council, she brought together a developer, citizens, the TRCA, City of Toronto and Oak Ridges Moraine Land Trust to turn a proposed golf course development into a protected valley and forest on the Oak Ridges Moraine. Susan is always eager to engage in conversations about how we can create healthy communities. Prior to starting her own planning practice, she held executive and management positions in the non-profit sector including the Oak Ridges Moraine Land Trust, the Greenbelt Foundation and the Green Economy Centre. Susan has a Masters degree in land use planning. When she isn’t working, Susan is gardening, hiking on the Oak Ridges Moraine or spending time with family and friends. Read Susan’s blogs here.

Karajaberlian | Managing Director

Having grown up witnessing the depletion of natural resources in her country, Suzanne pursued a graduate degree in environmental geochemistry to take an active role in protecting nature and all its inhabitants. Suzanne made the leap from working in the corporate sector in the U.S. to the environmental sector with her move to Canada in 2008. After working in energy conservation on demand-side management projects, she moved to an operational role utilizing her analytical background and corporate experience to help deliver outcomes more effectively. At Environmental Defence, she oversees the internal operations and leads the public engagement strategy.
