If you’re comparing post hole digging companies in Toronto, the honest answer to “who’s the best” comes down to three things. Do they dig below the frost line every time. Do they carry a valid Ontario One Call locate before they start. Do they own the right equipment for Toronto’s unstable, clay heavy soil. City Wide Post Hole Digging does all three on every job, from fences and deck footings to pergolas, mailbox posts, and commercial bollards, across the City of Toronto and the wider GTA.
This guide walks through exactly what separates a properly done post hole from a fence that leans in three years, plus our full pricing sheet by service area, so you know what to expect whether you hire us or someone else.

What a Professional Post Hole Digging Company Actually Does
Post hole digging sounds simple. Dig a hole, drop a post, add concrete. In practice, a professional job includes several steps most DIYers and unlicensed crews skip:
- Utility locate request through Ontario One Call before any tool touches the ground.
- Depth calculation based on the structure (fence, deck, pergola, gate, bollard) and the local frost line.
- Soil assessment. Clay, sand, fill, or bedrock all change how the hole is dug and how it’s backfilled.
- Correct hole diameter, sized to leave room for the post plus concrete or compacted backfill.
- Accurate placement on the client’s own markings.
- Clean set with the post plumb and secure in the hole.
Skip any one of these steps and the post eventually leans, heaves, or sits crooked. This is the checklist City Wide Post Hole Digging follows on every property, whether it’s a single mailbox post in Etobicoke or a full fence line for a farm property near Uxbridge.
The Toronto Frost Line: Why Depth Is Non Negotiable
In Toronto, soil typically freezes to a depth of roughly 3 to 4 feet (about 0.9 to 1.2 m), and most GTA building departments and contractors work to a practical standard of around 42 inches below grade for load bearing posts. If a post sits above the frost line, the freeze thaw cycle, which can repeat dozens of times over a Toronto winter, pushes the post upward year after year. That is the single biggest reason fences and deck posts start leaning within two or three years.
Recommended post hole depths for the Toronto/GTA area:
| Structure | Typical Depth | Notes |
|---|---|---|
| Standard 4×4 fence post | 32 to 36 in | Deeper in clay or exposed, windy sites |
| 6×6 post / larger structural post | 42 in | Our standard set depth for 4×4 and 6×6 posts |
| Deck footing | 4 feet (48 in) | Clears frost line, carries vertical load |
| Bollard | 36 to 48 in | Depends on the impact protection purpose |
| Pergola / gazebo post | 36 to 42 in | Treat like a fence post unless roof loaded |
These are general planning figures, not a substitute for an on site assessment. Soil conditions, structure height, and load can all shift the right depth for your specific project. City Wide Post Hole Digging measures each hole against these benchmarks rather than guessing, which is the difference between a footing that lasts and one that needs to be redone.
Ontario One Call: The Law You Can’t Skip Before Digging
Every dig in Ontario, including fence posts, deck footings, and even planting a tree, legally requires a utility locate through Ontario One Call, requested at least five business days in advance. This applies to homeowners and contractors alike, on public or private property, and it applies to hand digging as much as it does to auger or excavator work. Recent Ontario One Call data found that 1 in 4 residential digging projects results in accidental damage to underground infrastructure, largely because homeowners don’t realize the law applies to small backyard projects.
Before booking your job, make sure you (or your locate provider) have a valid Ontario One Call ticket on file. That is a liability step a lot of “handyman with a post hole digger” operations skip, and it’s the one that protects your property, your neighbours’ utilities, and you.
Hand Digging vs. Auger Drilling: Which Wins in Toronto Soil?
Not every job needs the same tool, and a crew that only owns one piece of equipment will use it whether or not it’s the right fit for your yard.
- Hand digging: Best for tight access sites (narrow side yards, laneway houses, downtown condo patios) or spots where powered equipment can’t get through a gate.
- Auger drilling: The workhorse for most residential fence lines and footings. Fast, controlled, and efficient through standard GTA clay and mixed soil.
- Helical (screw) piles: An alternative to poured concrete footings, useful where fast, low disturbance, all season installation is needed for decks and bollards.
City Wide Post Hole Digging brings both auger drilling and hand digging to every job (hand digging is available as an add on service) and matches the method to your soil and access instead of forcing one tool through every yard.
Toronto’s Soil Isn’t Uniform: Plan for Your Neighbourhood
Soil composition shifts noticeably across the GTA, which is one reason a copy paste national franchise often underquotes or under digs local jobs:
| Area | Common Soil Condition | Digging Consideration |
|---|---|---|
| Scarborough, Etobicoke, North York | Dense clay | Slower auger progress, deeper minimum recommended |
| Vaughan, Markham, Richmond Hill | Clay heavy, newer subdivisions | Consistent depth critical due to heavy clay expansion |
| Downtown Toronto, older Toronto neighbourhoods | Fill, rubble, tight lots | Hand digging or additional labour often required |
| Mississauga, Oakville, Burlington | Mixed sand/clay | Access and drainage matter more near established landscaping |
| Barrie, Innisfil, Bradford | Mixed rural and clay soil | Larger properties, farm posts, more open access |
A company that digs across the whole GTA daily, rather than one or two neighbourhoods, builds a genuine feel for these differences. That local pattern recognition is real experience, and it’s a factor in why a job goes faster and holds up longer.

Common Mistakes Homeowners and Unlicensed Crews Make
- Digging above the frost line to save time. This is the single biggest cause of leaning fences and heaving posts.
- Skipping the Ontario One Call locate, which is illegal and risks utility damage, fines, and injury.
- Wrong hole diameter. Too narrow leaves no room for concrete or backfill; too wide wastes material and weakens the footing.
- No drainage consideration in clay heavy soil, which traps water against the post and accelerates rot or frost heave.
- One tool for every job, forcing a small handheld auger through dense clay or old fill instead of switching to hand digging.
