Cahill Achieves PAR Bronze Certification

We recognize the mutually beneficial impact of business development with Indigenous-owned businesses, the value that Indigenous people bring to the workplace, and the potential of Indigenous communities. In 2018, Cahill committed to working toward certification in the CCAB Progressive Aboriginal Relations (PAR) program. We’re proud to say we’ve achieved the PAR Bronze Level. As we continue this certification process, we are committed to working closely with our community partners to do our part in the economic and cultural reconciliation with Indigenous peoples across Canada.

Life at Cahill


The Spirit of Giving

At Cahill, being a good citizen is more than a guiding principle, it’s an active part of our culture. Years ago, our employees were gifted a turkey for the holidays. But with community in mind, they decided to donate the money that would be used for turkeys to those in need through St. Vincent de Paul. What began as a simple gesture of kindness has turned into an annual giving initiative that supports over 125 families every year. It’s just one of the many ways our employees contribute to the communities in which we live and work. To us, that’s what building beyond is all about.

Introducing Makwa-Cahill

In 2021, Cahill partnered with Makwa to form Makwa-Cahill, the first nuclear-qualified Indigenous fabrication facility in the Owen Sound, Ontario area. This 26,000-square-foot fabrication facility, supported by the extensive technical capabilities of the Cahill Group, possesses all required nuclear and non-nuclear quality registrations to support pressure and non-pressure boundary fabrication scopes. The opening of the Makwa-Cahill facility represents the start of significant employment, training, and skill development opportunities for local Indigenous peoples. Cahill is proud of our commitment to developing mutually beneficial partnerships with Indigenous communities.
