Before joining the U of A, he was a teaching fellow at Queen’s University in the economics department, then an assistant professor at HEC Montréal’s Institute of Applied Economics and later a visiting scholar at the Strategic Policy Branch of Environment Canada. He also served as academic director of the Centre for Applied Business Research in Energy and the Environment (CABREE) at the Alberta School of Business between 2014 and 2022.

By drawing on his expertise in constitutional law, environmental science and environmental economics, Leach has advised various levels of government on climate change and oil and gas industry policies, including serving as chair of the Government of Alberta’s Climate Leadership Panel in 2015. Leach has appeared multiple times as an expert witness before Standing Committees of the Senate and the House of Commons. Leach has served as an economics and policy consultant for Environment and Climate Change Canada and other federal government departments, the National Roundtable on the Environment and the Economy (NRTEE), the Auditors General of Alberta and Canada, Alberta Environment, Alberta Finance and Enterprise, and Alberta Energy. Leach is also a contributing writer to a variety of news publications, with over 200 articles published by major media outlets such as CBC News, The Globe and Mail, and Maclean’s.
