Ontario One Call is a not-for-profit organization that receives locate requests & notifies utility owners with underground facilities at proposed dig sites.
ON1Call became a not-for-profit corporation August 11, 2011. The Ontario Underground Infrastructure Notification System Act, 2012, was passed in June 2012, thereby making ON1Call a Statutory Corporation. Under the Act, ON1Call is also responsible for ensuring compliance with the Act’s regulations. The bill stipulates that all owners of underground infrastructure must register their infrastructure

Summer digging season is in full swing.
If your project plans have changed since your original locate request, you may need updated locates before continuing work.
This includes changes to:
▪️ Dig area or location
▪️ Depth of the dig
▪️ Adding more fencing
▪️Extra landscaping
Even small changes can place digging closer to underground utilities that were not identified in the original locate.
Don’t assume previous locates still apply.
Before continuing your project, make sure your location information matches the work being completed.

Let’s shine a spotlight on those raising the bar for safety across our industry.
During Trench Safety Stand Down Week, June 15–19, Ontario One Call is reminding excavators, contractors, and crews that safe excavation starts before the ground is broken.
This week encourages the construction and utility industries to pause work and focus on trenching hazards, protective systems such as sloping, shielding, and shoring, and safe excavation practices that help prevent injuries and fatalities on job sites.
A critical part of trench and excavation safety is knowing what’s below before digging begins.
Before any excavation project:
▪️Request locates
▪️ Identify underground infrastructure
▪️ Follow safe digging procedures
▪️ Protect workers on site
Trenching hazards are preventable with proper planning, training, and safety protocols.
Visit OntarioOneCall.ca and Click Before You Dig - It's The Law.
A project may look simple above ground, but what’s below ground is not always visible.
Communication lines, hydro cables, gas lines, and water infrastructure can run through your property in unexpected places.
Before starting any digging project this summer, take the extra step to submit a free locate request.

Ontario One Call reminds homeowners to stay cautious following recent reports of door-to-door contractors delivering poor-quality work or incomplete work.
While most contractors follow proper safety procedures, these situations can pose a serious public safety risk, including potential damage to underground gas lines, electrical cables, and other critical infrastructure.
️❗Any project involving digging requires a locate request.
Before work begins, always confirm that:
▪️A locate request has been submitted at OntarioOneCall.ca
▪️Locate markings (paint or flags) and/or locate documentation have been received and reviewed by your contractor before work begins.
If a contractor suggests proceeding without locates, this is unsafe and not compliant with Ontario regulations.
Digging without locates can damage underground infrastructure and put your safety, property, and community at risk.
No digging should take place without first submitting a locate request. Click Before You Dig – It’s The Law at OntarioOneCall.ca.
Taking a moment to verify this step can help you prevent unsafe work, costly damage, and project issues.

Hiring a contractor this summer?
Before work begins, ask:
▪️ Has a locate been requested?
▪️ Are all locates complete?
▪️Are markings visible onsite?
Safe digging is everyone’s responsibility.
