THE MANTELLA DIFFERENCE
Mantella Corporation is one of the largest Canadian privately held family-owned real estate and land development companies. Mantella Corporation uses an active in-house management team and trusted long-term relationships to fulfil its various investment strategies predominantly in the Greater Toronto area. We are known as market leaders who maintain an entrepreneurial culture and capitalize on our strengths as decisive decision makers.
A History of Mantella
In 1946 Anthony Mantella, a construction worker with 20 years experience, had a dream to have his own company. With very little money and a very strong will, he took a chance and built a home for himself. He eventually sold this house and built another one next door. The company was called Acme Home Builders.
With the help of his two sons, Paul and Frank, in 1954 the company became A. Mantella and Sons Limited. By 1958 they had built over 500 homes. A. Mantella and Sons Limited also began building industrial plants on speculation and were successful in selling over 42 of them by 1958, ranging in size from 3,000 square feet to 20,000 square feet. Since then, over 6 million square feet of commercial real estate projects have been developed.
Mantella Corporation saw opportunities to diversify its investment base and in 2008 launched Mantella Venture Partners. This grew to a series of three venture capital funds investing in early-stage technology companies. These investments have now been fully realized.
Leaning on its exceptional real estate investment track record, in early 2024 the company began transitioning from a traditional family office to becoming a fiduciary to external investor capital. By late 2024, the investment platform Mantella Realty Partners Corporation was established, and in 2025 closed on the first real estate acquisition with an external equity partner on this platform.
Today Mantella Corporation celebrates 80 years in business and is still one of the largest, privately-owned development companies in Canada, managing and developing millions of square feet of owned facilities. Mantella Corporation and Mantella Realty Partners Corporation continue to be active in the leasing, development and repositioning of primarily industrial and retail properties throughout the Greater Toronto Area and Montreal.
Chairman’s Message
It all began with one house. When my grandfather, Anthony Mantella, built his first home in Toronto in 1942, he knew he had the seeds for a burgeoning real estate development business: integrity, honesty, expertise, and a desire to expand.
And he passed on these qualities to his two sons, Paul and Frank, so that they too could take part in the success of the business. Within a few short years, my grandfather, father and uncle diversified their business to include vast commercial properties.
It’s that visionary focus on embracing change and investing in the future that has made Mantella Corporation what it is today.
In everything we do, we rely on the qualities that our family has firmly grounded in our business. We build relationships with our clients and partners that are based on a passionate vision for the future, a conscientious, hands-on focus on the present, and a proud and established foundation of more than 50 years in the business.
It’s one of the reasons why, in 2008, we diversified our assets to invest in strong, vibrant Internet software businesses in Ontario through Mantella Venture Partners. Technology and real estate development don’t normally go together. We know, however, that the transformative and game-changing power of technology, combined with our established excellence in real estate development across Ontario, will ensure the Mantella vision continues for future generations.
Our focus on the future also includes giving back to the communities that helped us grow. Through our volunteer efforts and funding of charities that support children, animals and healthcare, we hope to further expand Mantella’s vision for our business, our community, and our world.
We take great pride in the relationships we have built with our clients and partners over the years, and we look forward to continuing that tradition with new, exciting relationships in the years to come.
