Expert Consultants

Regulatory industry matters and regulatory approvals of energy projects call for coordinated deployment of a wide range of disciplines including engineering, finance, commercial, environmental, land access and stakeholder consultation. Strategic and effective participation in energy industry matters and successful project development require regulatory counsel and advisors well versed in those various disciplines and, periodically, from many of them concurrently.

Regulatory Law Chambers is pleased to have available specialists and advisors to draw on from time to time as the demands of larger project approvals and proceedings may warrant. These select industry experts have distinguished themselves in related areas of practice and provide expertise and support for larger matters as needed.
