William Kelly - Founder & Past President

William (Bill) Kelly was the company's founding father and company namesake. Bill and his wife, Margaret, came to Canada in 1956 and after years of working for others, his entrepreneurial spirit got the better of him and with the help of Margaret, they began operations out of their house in 1972. Through his ability to recognize and seize opportunities, Bill strategically grow the company slowly and deliberately upward and outward.

Bill was a Journeyman Plumber and Gasfitter not only in Canada but also in the UK. He had an extensive and well rounded background in all areas of the business - field and office. His knowledge proved to be an invaluable asset to the company even beyond his retirement as he continued to invest many dedicated years in the company.
