That Hold Up

Alderstone Consulting Inc. is an independent engineering assurance firm based in Toronto, Ontario. We specialize in hazard identification, risk assessment, system safety, and security assurance for complex infrastructure and transit environments.

Our work is built on a single principle: that safety-critical decisions must be traceable, defensible, and grounded in recognized engineering standards. We help project teams, operators, and procuring authorities achieve exactly that.

As a boutique firm, we bring focused expertise to every engagement — no generalist staffing, no overhead. What you get is disciplined, evidence-based assurance work delivered with the rigor that safety-critical environments demand.
