About Us

The Roncalli Group Difference

Yes, we do things differently. Repeat clients are a major testament. It’s not just about costs and quality. It’s the nature of the relationships we form.

Since 1950

In 1950 our father and uncle moved to Canada from a small town in northern Italy.

Experienced in Old World architecture, the two formed a business in 1951. The company quickly began making a name, synonymous with reliability and trust. The two sons – Rico and Dave – of the oldest brother began learning the trade and the business, continuing the business after their father’s retirement. Although Roncalli Group primarily works in Ontario, they have consulted in both residential and commercial sectors with clients as far away as Nova Scotia, Brazil and frequently in Florida. With access to over 70 of Ontario’s highly skilled women and men, our team executes each endeavour professionally…to a standard that is fittingly unrivaled. We specialize in:

  • Custom Homes

  • Vacation Properties

  • Additions & Renovations

  • Commercial Construction


At Roncalli Group, we combine our experience, transparency, and passion to ensure the quality of work. This translates into exceptional value.


Customers demand honesty and fairness. That’s why we provide information, options, and costs currently available.


Our experience and work ethic exceeds our customers’ expectations. We guarantee it!

We endeavour to include all specifications for your project, ensuring all ideas are built into your home or office from the outset.

We correspond and meet with clients, their designers, architects, engineers and consultants to assure continued satisfaction with the progress of construction. At the end of the project we remain available for your complete satisfaction.


We invest time effectively and efficiently, allocating management to each project, ensuring the highest quality of construction. We guarantee that every client’s needs are understood and accomplished.
