Our Story
All Pro Systems was founded by two industrial pipefitters who spent years working together on job sites — including in the oil fields of northern Alberta — before returning to Ontario with a shared goal: build a mechanical contracting company that puts quality first.
What started as a two-person operation has grown into a team of skilled tradespeople serving clients across Southern Ontario. We've expanded our services, our crew, and our client base — but the founding principles haven't changed. Show up prepared, do the work right, and stand behind it.
Our Team
All Pro Systems is made up of experienced, certified trades professionals with backgrounds in industrial pipefitting, HVAC, welding, rigging, and fabrication. Our people have worked in demanding environments — from manufacturing plant floors to large-scale construction sites — and they bring that experience to every project.
Where We Work
Our team is rooted in Southern Ontario, with crew members located in Brant County and the Waterloo Region. We regularly take on projects throughout the province and are experienced in working across multiple sites and regions as projects require.
Our Values
Craftsmanship: We take pride in the work. Every weld, every connection, every installation is done with care and attention to detail.
Safety: Our people go home at the end of every shift. Safety isn't a checkbox — it's how we operate.
Accountability: We own our work. If something isn't right, we make it right. Our clients know they can count on us.
Partnership: We work with our clients, not just for them. We listen, communicate, and treat every project like it matters — because it does.
Technical Standards and Safety Authority (TSSA)
All Pro Systems is certified by the Technical Standards and Safety Authority (TSSA) — Ontario's regulatory body for technical safety and compliance. Our TSSA certification covers pressure piping and process systems, meaning you can trust that our installations meet the standards required by Ontario law.
For facility managers and procurement teams: working with a TSSA-certified contractor isn't just best practice — in many cases, it's a regulatory requirement. All Pro Systems keeps your project compliant.
