In Ontario, post holes need to be a minimum of 4 feet (1.2 metres) deep to sit below the frost line and prevent shifting during freeze-thaw cycles. Exact requirements may vary by municipality, so confirm with your local building department before starting.

We specialize in digging and setting — we do not supply posts or concrete. We recommend picking up your materials from a local hardware store ahead of your appointment. If you’re booking a Dig & Set, just have everything on site and we’ll handle the rest.

In good conditions with standard soil, we can typically dig 20–40 holes per day. Rocky ground, heavy clay, or tight access areas may affect that number. We’ll give you a realistic timeline when we assess your job.

Yes — locates are required by law before any digging begins. Contact Ontario One Call (on1call.com) to have underground utilities marked prior to your appointment. Hole Digger can help walk you through the process if needed.

A fence post hole is dug to set a wooden or metal post in concrete. A sonotube is a cylindrical form used to create a solid concrete pier, typically for decks or larger structures. Sonotubes require a wider hole and more concrete than a standard fence post hole. Let us know what your project involves, and we’ll point you in the right direction.
