About Contractors Niagara

Owned and operated by Mike Ljiljanic.


Our Story

Our Founder Mike Ljiljanic’s father was a professional contractor for decades, eventually passing down the trade to his son. He taught Mike everything he needed to know about drywall, HVAC, and other trades to eventually create his own business and career. For decades, Mike, Carmine (Contractor Niagara’s Co-Founder), and their team have served the Niagara region with contracting and property management services that are reliable and affordable.
