Which director was that?  This is a list of the BCUC commissioners, and they were all appointed under the Liberals.

If you meant BC Hydro, all the directors were appointed before the election.  The chairman was put in by the NDP.  

Kenneth G. Peterson was appointed chair of BC Hydro on July 19, 2017.

Mr. Peterson's 40-year career spans a wide range of assignments in the electricity industry. The last 10 years of his professional career were spent as CEO of Powerex, the marketing and trading subsidiary of BC Hydro. He also served as a trustee of the North American Electric Reliability Corporation since 2006, where he applied his industry experience to the physical and cyber-security reliability challenges facing utilities.

Such a toady!  No industry experience at all, and not the most knowledgeable person in BC about power demand!
