Our Mission

At Ontario Iron, our mission is to eliminate inefficiencies in construction by raising the standard of rebar supply. We focus on precision detailing, consistent processing, and uncompromising quality to ensure every bar delivered performs exactly as engineered. By streamlining fabrication and reinforcing accuracy, we help contractors and developers save time, reduce waste, and build with confidence.”

Our Journey

Ontario Iron was founded with a clear vision to bridge the gap between quality steel fabrication and seamless on-site installation. We noticed that many projects faced delays and cost overruns due to poor coordination between fabrication shops and installation teams.

We set out to change that. By offering end-to-end structural steel services under one roof, we’ve made it possible for our clients to have a single point of contact from project estimation to final inspection.

Over the years, our team has worked on hundreds of projects across Ontario, from custom home builds in Toronto to multi-storey commercial developments in Mississauga and industrial facilities in Hamilton. Every project, regardless of size, receives the same commitment to quality, timelines, and client satisfaction

From Toronto to Ottawa, Mississauga to London, Ontario Iron proudly serves clients across the province with timely delivery, competitive pricing, and exceptional customer service.
