The structure
behind the vision.
Rialto Engineering is an Ontario structural engineering firm providing design, assessment, and rehabilitation services for buildings — with drawings you can build from and answers you can rely on.
What we do
Engineering across the full life of a structure

Working with Rialto
Small firm. Senior attention. Every project.
When you call, you speak with the engineer sealing your drawings — not a project coordinator. That's how we keep designs practical, schedules honest, and reviews fast.
About the firmAbout
A structural practice built on clarity
Rialto Engineering Inc. is an Ontario structural engineering firm named after one of history's great lessons in engineering judgment: the Rialto Bridge in Venice — a single bold span that its critics said would never stand, and that has carried the city for over four centuries.
That's the standard we design to. Structures should be efficient without being fragile, ambitious without being risky, and documented so clearly that a contractor never has to guess.
We serve architects, contractors, property managers, and homeowners across Ontario. Whether it's a residential renovation, a commercial building, or an industrial retrofit, every project gets the same discipline: rigorous analysis, code-current design, and drawings prepared with care.
Our deliverables follow a consistent drafting standard — every drawing that leaves this office is sealed, checked, and drawn to be read on site, not just in the office.

How we work
Three commitments on every project
01
Buildable first
We design for the crew on site. Connections that can actually be made, sequences that can actually be followed, details drawn at a scale you can read.
02
Straight answers
If something can be simplified, we'll say so. If something is a real risk, we'll say that too — early, in writing, with options.
03
On schedule
Permit sets, reviews, and inspection reports delivered when promised. We size our workload so your project never waits in a queue.
