Survey Markings on Your Property

Before you start digging on your property, make sure you know what’s below. Whether you're planting a tree, installing a fence, or building a deck, hitting underground utilities can be dangerous and expensive. Always contact Ontario One Call to request a locate before you dig—it’s easy, it’s free, and it’s the law. Stay safe and avoid costly damage by planning ahead.

Coloured markings on or in front of your property notify of underground facilities. They are most likely there because:

• You or your neighbour requested locates through Ontario One Call before starting a construction project. You may want to ask your neighbours whether they are doing any work, such as installing a fence or an in-ground sprinkler system. 

• The City is planning to repair water and sewer lines or rebuild roads or sidewalks. Check the to see if a City project is underway in your area.

• A utility company is planning to dig to repair or upgrade their lines.
