Leadership Team

David Del Mastro

President, CEO & Founder

David Del Mastro was raised in a small rural community just outside of Wasaga Beach, Ontario. His vision for what is known today as the Deltro Group of Companies originated when he helped his uncle complete electrical wiring for the new addition to the family home. From that point on, he knew he wanted to pursue a career in the electrical field.

Following his graduation from high school, David started his electrical apprenticeship at George Brown College in Toronto. Finishing at the top of his class, David received his Red Seal Endorsement as a 309A- Electrician – Construction and Maintenance. Soon after, David achieved his designation as a Master Electrician.

At only 23 years old, David founded Deltro Electric Ltd. which is now entering its 30th year. With a keen eye for problem solving, David challenges conventional methods of thought as he believes there can always be a better way of completing a task. This mindset has driven him, and Deltro to much of its success over the years.

Today, David is the President and Chief Executive Officer of the Deltro Group of Companies. Though he focuses much of his time on business development and relationship building,  on occasion, David  lends his expertise to the operations team for complex electrical problem-solving.

Outside the office, David spends quality time with his family and is an avid sports fan.
