Sander specializes in environmental, regulatory and Aboriginal law issues for natural resource development projects. He has experience with matters before the National Energy Board, the Alberta Energy Regulator (and its predecessor the Energy Resources Conservation Board), the Ontario Energy Board, the British Columbia Environmental Assessment Office, the Alberta Utilities Commission, the Public Lands Appeal Board and federal -provincial Environmental Assessment Joint Review Panels. Sander also has experience with regulatory, environmental and Aboriginal matters before the Alberta Court of Queen’s Bench, the Alberta Court of Appeal and the Federal Court of Canada. The subject matter of Sander’s recent regulatory work includes oil and natural gas pipelines, oil sands (both mining and in situ), LNG export, offshore drilling, hydro-electric generation, mining (including coal, metal, potash and diamonds), natural gas processing, electricity transmission and contaminated lands. He also regularly advises clients on their obligations to Aboriginal groups and negotiates impact benefit agreements with Aboriginal groups on behalf of resource developers.
