If you are planting a tree, building a deck, digging a garden, or planning any other project that requires you to dig, you must contact Ontario One Call at least 5 days in advance.
Ontario One Call communicates with all of the owners of buried infrastructure, including Halton Hills Hydro so that they can come out and mark the location of buried lines or cables.
This is a free service for excavators and homeowners.
