Our Mission
We are Greater Sudbury’s single-source environmental management partner, with over 20 years of experience. Our approach keeps critical environments stable, protected, and audit-ready—so your team can focus on their core mission without worrying about the infrastructure beneath them.
The Custodian Standard
We hold ourselves to a compliance-first standard that goes beyond basic upkeep. Every inspection, maintenance routine, and work order is documented and executed to meet or exceed WSIB and WHMIS regulations.
Our Environmental Service Technicians are vetted through a rigorous, accountability-focused hiring process—because the personnel entering your facility must be as reliable as the service itself. If an operational corner is cut on our watch, we cut that segment of your invoice. No delays, no excuses.
Why Partner With Us
When you choose Custodian Service Industries, you get a single point of contact, a single standard of excellence, and absolute accountability. We eliminate the fragmentation of managing multiple vendors across shifts and zones. We understand that downtime is not an option and we back that understanding with a contractual guarantee, not just a promise.
