Our Story


The Wilson Group was founded in 1967 by Italian immigrant Marcello De Lio. What began as a plastering company soon expanded after his son Frank De Lio joined the company in 1987. Under his management, The Wilson Group expanded to a general contracting company. The expansion was made possible by his background in civil engineering. With over 50 years experience, the company continues to proudly serve the Greater Toronto Area and Niagara region. Never outgrowing his humble roots, Frank De Lio still oversees every job site no matter how large or small.
