Before You Dig: A Homeowner's Guide to Ontario One Call for Your Ottawa Renovation

You’ve finalized the plans for your dream home addition, envisioned the perfect multi-level deck, or decided to add an egress window to your new basement suite. The excitement is building, and you’re ready to break ground. But before the first shovel hits the dirt, there’s a critical step that ensures the safety and success of your entire project: understanding what lies beneath the surface. For any project in Ottawa that involves excavation, a call to Ontario One Call isn’t just a good idea—it’s the law, and it’s your first line of defense against costly damages and dangerous accidents. Many homeowners feel overwhelmed by the technical aspects of a renovation, fearing unreliable contractors who might cut corners. That's why understanding this process is so important. At Saywood Construction, we manage every detail, starting from the ground down, to ensure your project is built on a safe and solid foundation.

What is Ontario One Call and Why is it Essential?

Ontario One Call is a free public safety service that connects you with the owners of underground infrastructure. When you or your contractor request a “locate,” One Call notifies its members—utility companies like Hydro Ottawa, Enbridge Gas, Bell, and Rogers—who then send representatives to mark the location of their buried lines on your property. This prevents you from accidentally digging into a natural gas line, a hydro cable, or a critical water main.

Why is this non-negotiable for your project?

• Safety: The most important reason. Striking a gas or electrical line can have catastrophic consequences for your family, your property, and the work crew.
• It’s the Law: The Ontario Underground Infrastructure Notification System Act legally requires anyone digging to request a locate at least 5 business days before starting. Failing to do so can result in significant fines and liability for damages.
• Preventing Costly Damage: Repairing a severed fibre optic cable or a water line can cost thousands of dollars and cause major project delays. A proper locate eliminates this risk, addressing the common fear of unexpected budget overruns.
• Peace of Mind: Knowing your project is compliant and safe allows you to focus on the exciting parts of your renovation. It’s a key part of the professional project management and reliability that homeowners prioritize.

The Locate Process: What to Expect on Your Property

When you work with a professional general contractor, we handle the entire Ontario One Call process for you. We believe in clear, consistent communication, so here’s a simple breakdown of what you can expect to see happen at your home:

1. The Request is Placed: About a week before excavation is scheduled, we submit a detailed request to Ontario One Call. This includes your address, the exact location of the dig site on your property, and the type of work being done, whether it's for deck footings or a new home addition foundation.

2. The Waiting Period: Utility companies have five business days to respond to the request. During this time, you’ll see representatives from different companies visiting your property.

3. Flags and Paint Appear: Don't be alarmed by the sudden appearance of small flags and spray paint on your lawn! These markings are a good sign that the process is working. Each color corresponds to a specific utility, following a universal code:

   • Red: Electricity
   • Yellow: Gas, Oil, or Steam
   • Orange: Communication (Phone, TV, Fibre)
   • Green: Sewer and Storm Drains
   • Blue: Potable Water

4. Receiving the 'All Clear': Once all utilities have marked their lines or confirmed they have no infrastructure in the area, we receive a locate sheet (often called a clearance report). No digging can begin until this document is in hand. It serves as our map, showing us exactly where we can and cannot excavate safely.

Ottawa-Specific Challenges & Common Misconceptions

Every property is unique, and in a city with a mix of new suburbs and historic areas, we encounter specific challenges. It’s a common misconception that for shallow digging, like for a simple fence post, a locate isn't needed. In reality, some utility lines are buried just a few inches below the surface.

In older Ottawa neighborhoods like The Glebe, utility maps can be less precise, making on-site markings absolutely essential. Furthermore, our climate presents unique issues like frost heave, which requires us to dig deeper for footings to ensure long-term stability, increasing the importance of knowing what's below.

It's also crucial to understand that Ontario One Call only covers public utilities. It does not locate private lines you may have installed, such as an electrical line running to a detached garage, a gas line to a pool heater, or a septic system. As part of our thorough process, we help you determine if a separate private locate is needed to ensure every single line is accounted for before we start.

This comprehensive approach is part of our commitment to quality craftsmanship and protecting your investment. We navigate the complexities so you don't have to.
