Preserving the past and building the future

About Us


Our Story


The Atwill-Morin family has been in the construction business for over 50 years

Brothers Jonathan, Matthew and Mark Atwill-Morin are the third generation to run the business. Over the years, they have surrounded themselves with partners to expand and add new specialties to the company’s service offering.

Since 2004, Joshua Johnston and Regina Grundmann have been directing and developing stone masonry restoration activities in Ottawa, under the Atwill-Morin Ontario banner. In 2014, the scaffolding installation and rentals division, Impact Scaffolding, was born. It was also in 2014 that Nicolas Croteau joined Atwill-Morin. He was responsible for developing the concrete and structure sector of the company under the Béton concept A.M. and Atwill-Morin Structure banners. He is now responsible for the acquisition and integration of new companies, in accordance with Atwill-Morin’s growth plan. The most recent additions to the group are Les Carrières Ducharme and Restaurations DYC.

Since 2017, Atwill-Morin has been established in Québec City, whose activities are led by Sébastien Delli-Colli under the Atwill-Morin Quebec banner. In 2018, the company entered the new masonry market by acquiring Maçonnerie USC. In 2020, Pierre Whitty joined the Atwill-Morin Structure team to lead the concrete and structure activities in the Ottawa and Gatineau regions. The same year, expansion continued, in Toronto, with entrepreneur Glen Pestrin as a partner of Atwill-Morin & Associates.



Atwill-Morin currently employs nearly 1,000 skilled masonry, concrete, and scaffolding professionals in the Montreal, Quebec City, Ottawa, and Toronto areas. Our work stands the test of time, and we are constantly striving to become even better.

Keep Building Better


Respect is the cornerstone of our organization:

Our respect for our trade, our uncompromising respect for industry standards and ethics, our corporate culture, and our love of challenges, innovation, and a job well done drive us to push the limits and fully invest ourselves in everything we do. With passion.

We show respect for the jobs entrusted to us by constantly focusing on our ultimate goal: bringing our clients’ ideas and vision to life.

Our respect for the environment and our natural and built heritage is the foundation of our vision of a better tomorrow for ourselves, our families, and future generations. It has always been a source of inspiration and pride for our company.

Respect for people is our bottom line. We value the safety of our clients, employees, partners, and fellow citizens—the dreamers, thinkers, builders, and people who use the places we build.

With and for all these people, we keep building better.
