Charles is co-head of Torys’ Infrastructure and Energy Practice and lead of its Energy Regulatory Team. His practice focuses on administrative law and project development in the energy sector. Charles advises generators (renewable and conventional), transmitters, and electricity and natural gas distributors in relation to regulatory, project development and contractual matters.

Charles regularly appears before the Ontario Energy Board on rates, licensing and leave to construct matters applications, some of which are the most complex and unique matters considered by that tribunal.
