Building your own fence can be an exciting and rewarding project. It gives you the freedom to design your outdoor space just the way you want it, all while saving on labor costs. However, before you start digging those post holes, there's one crucial step that many DIYers overlook: requesting locates for underground utilities.
In Ontario, Ontario One Call is the service you need to use to ensure you avoid damaging buried utilities like water, gas, electricity, and telecommunication lines. Failing to request locates can lead to accidents, service disruptions, and costly repairs. Here’s why it’s so important to request locates, and how to do it the right way.
Why Should You Request Locates?
Safety First: The most important reason to request locates is safety. Digging into buried utility lines can cause serious accidents, such as gas leaks, electrical shocks, or flooding. Even if your area seems safe, utilities may be buried deeper than you think. Requesting locates ensures you're aware of where utilities are located, protecting yourself and others.
Avoid Costly Repairs: Damaging an underground utility line can result in costly repairs, sometimes amounting to thousands of dollars. For example, damaging a gas line can be especially expensive and dangerous. Locates allow you to avoid this risk by providing you with the exact location of utility lines, ensuring you don’t dig in the wrong spots.
Legal Compliance: In Ontario, it’s required by law to request locates before digging. If you fail to request locates, you may face fines or penalties. Ensuring compliance not only keeps you out of trouble but also helps protect the infrastructure that serves your home and community.
Protecting Your Property and Your Neighbors: Some utility lines may be shared with your neighbors, while others may serve your home exclusively. Damaging or disturbing these lines could cause disputes with your neighbors or even legal issues. Locates help you avoid these problems and ensure you're not disrupting services.
How to Request Locates in Ontario
Ontario One Call makes it easy to request locates for underground utilities before you start digging. The process is free, quick, and essential to a safe fence installation. Here’s how you can do it:
Step 1: Visit the Ontario One Call Website
Start by visiting the Ontario One Call website at https://www.ontarioonecall.ca/. This is the official site for requesting locates and finding all the details you need to proceed.
Step 2: Submit Your Request Online or by Phone
You have two ways to request locates with Ontario One Call:
Online:
You can fill out an online request form on the Ontario One Call website. The process asks for information such as your contact details, the location of your property, and the area where you plan to dig. The form is simple to fill out and guides you through each step.
By Phone:
If you prefer to speak to someone directly, you can call 1-800-400-2255. A representative will help you submit your request and can clarify any questions you might have about the process.
Important Note: It’s recommended to request locates at least 5 business days before you plan to start digging, as utility companies need time to send technicians to mark the locations of any underground lines.
Step 3: Provide Accurate Information
When submitting your request, be as detailed as possible. The more information you provide, the more accurately utility companies can mark the underground lines. You’ll need to include:
Property Address: The location of where you’ll be working.
Type of Work: Let them know you're installing a fence.
Work Area: Specify where you plan to dig, especially the fence line or areas where you’ll be setting posts.
Step 4: Wait for the Utility Companies to Mark the Area
Once your request is submitted, utility companies will send technicians to your property to mark the locations of any underground utilities. These markings typically take a few days to complete, so be patient. The technicians will mark the lines with paint, flags, or stakes that show where utilities are located.
Step 5: Review the Markings
After the technicians mark the utilities, carefully inspect the markings before you begin digging. Make sure you understand where digging is safe and where it is not. If you’re unclear about any markings or the locations of the utility lines, don’t hesitate to contact Ontario One Call or the utility company for clarification.
Step 6: Start Your Fence Project Safely
Once you’ve reviewed the markings, you can proceed with your fence installation. Just be sure to avoid any areas marked with paint or flags indicating underground utilities. It’s always better to be cautious and double-check if you’re unsure about any markings.
When Should You Request Locates?
It’s essential to plan ahead. Request locates at least 5 business days before you start digging. Utility companies typically need this amount of time to send out technicians and complete the markings. However, be aware that during peak construction seasons, it might take longer, so the more time you give them, the better.
What to Do If You Find a Problem
If you notice an unmarked utility line or if there’s any confusion about the markings, do not proceed with your project until you have clarity. Reach out to Ontario One Call or the specific utility company for further instructions. It’s always better to take extra precautions than risk damaging utilities or injuring yourself.
