About us

About Us

At Onyx, we value relationships, deliver on our promises, and honour our handshakes. Every time. Every day.

Built on almost 100 years of founder experience, Onyx Mechanical was born out of a need to rescue a troubled mechanical construction project at Toronto’s Sunnybrook Hospital more than a decade ago.  A “mechanical contracting 911”  went out, and our leadership team answered the call, using their collective know-how to revive a project that was on the verge of flat-lining.

Since then – and through over 400 projects and counting – Onyx Mechanical Ltd has built a unique business model that allows us to say to the client “when you come to us, we stand with you.” We pride ourselves on our ability to deliver complex projects AND de-risk them.

As specialists, we don’t target every job that comes our way. Onyx’s success and growth came from a need in the industry to do things better, to break down the silos and work together in order to solve complex mechanical problems and provide accurate cost projections – and be accountable for them with one singular point of contact. We have solid relationships with other trade partners, providing cohesion and peace of mind throughout the entire process and across a broad spectrum of work and workplace circumstances. We found a better way. We build quality – and we build relationships – every time. Every day.

We are a Tier 1 mechanical contracting company and our priority is to safely deliver quality projects that are on time and on budget. Onyx Mechanical works extensively with the most notable stakeholders in the industry – just ask around.

There’s a lot more to the story. Contact us today to start a conversation.

For over seven years, Onyx Mechanical has reliably provided outstanding support and superb mechanical services.

We are very happy with Onyx Mechanical as a mechanical development partner and would be pleased to recommend them to our peers in the construction business.
