A long Legacy of building

Led by Julie Di Lorenzo and an exceptional leadership team, Mirabella Development Corporation is a legacy company of the Diamante Development Group, carrying on a long legacy of building. Beginning in 1982 – starting with a focus on high-rise concrete formwork, where some of the most technically difficult projects in Toronto were executed, such as Empire Plaza, Terminal Three International Airport, and Bata Shoe Museum – our company has evolved into a premier, multi-disciplinary real estate development company and city builder. Today, Mirabella Development continues to shape skylines in Toronto and beyond, having delivered thousands of residential units across Canada and Asia, with ambitious new projects in the residential, industrial and commercial sectors on the horizon.

Coming from a long family history of Italian construction professionals in North America, her grandfather immigrated from Italy to New York City in the early 1900s, helping erect some of the early foundations and structures of the city, while her father, Nick Di Lorenzo, was a dominant contractor and innovator in Toronto in the 1960’s and 70’s, inventing the “flying form” method of high-rise construction and bringing over the tall cranes from Europe that made it possible.

Starting out as a 16-year old girl delivering boxes of nails, plans and materials to concrete formwork sites, Julie Di Lorenzo has been part of our industry for over 40 years as an entrepreneur, real estate developer, and city builder, while simultaneously devoting her time and leadership towards innovating, improving, and supporting our communities.
