Please note these are currently being edited.

Owen Leggatt Stewart – President & Director, BC & Yukon (he/him)

Owen is a practicing lawyer who has been involved in constitutional litigation across Canada. Born and raised on the West Coast of Canada, Owen grew up fishing and camping—which fuelled a growing concern for conservation and environmental protection.

This led Owen to volunteer with environmental issues and organizations, something he has now been doing for over a decade. While Owen has deep roots in British Columbia, he has lived in or travelled to almost every province and territory in Canada, instilling a keen interest in local and national issues.

Owen briefly considered a career as an outdoor guide before questionably deciding that an office life would suit him better. Owen remains an avid backcountry camper and can be found gardening, fishing, or cooking in his free time.
