If you are planting a tree, building a fence or a deck, digging a new garden, or doing any project that requires you to dig, you must contact Ontario One Call at least 5 days before online. Ontario One Call will notify buried infrastructure owners that you plan to dig. Reps from each underground buried infrastructure owner will come out to mark the location of buried underground lines and cables on your property so that you can dig safely. Contacting Ontario One Call is free and will help protect your property and your loved ones. If an outside shut off location is required contact the Public Works Department at 705-474-4340 or by using the link below.
