Glenn N. Sturdy, B.Eng., began his work in electrical contracting with his family business at the early age of 14, working during summers and weekends as a labourer and equipment operator through high school.

From 1985 to 1990, Glenn attended Lakehead University and completed a Bachelor of Engineering in the electrical field, while continuing to work each summer at Sturdy Power Lines. During this time, Glenn learned the ins and outs of underground and overhead hydro distribution, as well as substation construction.

Following graduation, Glenn gained experience in construction, maintenance, and design. By 1991, Glenn became a BC Hydro Field Operation Manager in training, and in 1993, he took over as the junior Field Operation Manager in the North Shore region.

In 1994, Glenn assumed the position of General Manager at Sturdy Power Lines, where he expanded his abilities in customer service, job design, estimating, tendering, construction, inspection, and invoicing of a variety of projects.

From 1998 to 2002, Glenn was in charge of a large contract with Flamborough Hydro, which saw Sturdy Power Lines perform all of their utility operations.

Since November of 2002, Glenn has acted as President of Sturdy Power Lines. Glenn has also joined the boards and committees of various organizations including the Ontario Electric League, the Master Exam Board of the Electrical Safety Authority, and more.
