Thinking about a new deck, sunroom, or even some much-needed underpinning? If you’ve been researching foundation solutions, you’ve likely come across helical piles, also known as screw piles. But one of the first questions that comes to mind is: how much does helical pile installation cost in Toronto?
The short answer: it depends. The long answer? That’s exactly what we’re diving into today. From average pricing and local permits to soil depth and engineering reports, this guide will give you a clear picture of what to expect and how GAMCON helps you get it right the first time.
Key Takeaways Before We Dig In
- Helical piles in Toronto generally cost between $300–$700 per installed pile.
- Project type, soil conditions, depth, and permits all influence the final bill.
- Toronto homeowners often prefer screw piles because they’re faster, cleaner, and can be installed year-round.
- GAMCON provides transparent pricing, torque reports, and expert installation across the GTA.
Average Helical Piles Installation Cost in Toronto
When homeowners ask us, “What’s the going rate?” we like to be upfront. In Toronto, you’re typically looking at $300–$700 per pile. GAMCON’s pricing often falls between $350–$800 per pile, depending on scope and engineering requirements.
Let’s put this into context:
- Decks & porches: ~$300–$500 per pile
- Sunrooms & additions: ~$400–$700 per pile
- Underpinning & foundation repairs: $800+ per pile
Something many people don’t realize is that downtown Toronto jobs often carry a minimum mobilization charge; think $800 or so. That’s because moving compact equipment into tight laneways and backyards is a project in itself.
Competitors list similar numbers, which tells you this isn’t just sales talk. It’s the industry reality.
Factors That Influence Installation Costs
So, why can one pile cost $350 while another runs $800? Here are the big factors:
- Pile size & load capacity: Bigger structures need bigger piles, plain and simple.
- Soil conditions & frost depth: In Toronto, piles typically go at least 1.2 metres deep to meet the Ontario Building Code. Trickier soils may require more depth.
- Number of helices & extensions: If your pile needs to go deeper than 7 feet, each foot of extension usually adds $15–$30.
- Site accessibility: Those charming narrow downtown lots? They sometimes need specialty machinery.
- Engineering & torque reports: Every job requires proof of load capacity. The torque equation (P = Kt × T) is your guarantee that the pile can handle the design load.
- Permits & approvals: Between Toronto building permits, possible TRCA permit Toronto requirements, and Ontario One Call utility locate, there’s paperwork before you can even start digging.
- Taxes & mobilization: Don’t forget HST Ontario 13% and the standard mobilization charges.
Helical Pile Cost Breakdown (Toronto-Specific)
Here’s how costs typically add up:
| Cost Component | Typical Range | Notes |
| Materials | $150 – $300/pile | Shaft, helix plates, hot-dip galvanizing |
| Labour & Equipment | $100 – $250/pile | Operator, torque monitoring, machinery |
| Extension | $15 – $30/ft | Required if piles go deeper than 7 ft |
| Engineering Reports | $150 – $300 | Required for larger or high-load projects |
| Permits | $206.53 flat | Current City of Toronto fee (2025) |
| TRCA Permit | $240 – $535 | For ravine or waterfront properties |
| Utility Locates | Free | Ontario One Call is mandatory |
| Mobilization | $500 – $800 | Especially on small jobs |
| HST (13%) | Total × 13% | Applies across Ontario |
Helical Piles vs. Concrete Footings
Here’s where screw piles really shine.
Helical piles Toronto homeowners love because:
- They’re installed faster and cleaner.
- They work in any season, even the depths of winter.
- Minimal excavation means less disruption (and less mess to clean up).
Concrete footings, on the other hand:
- Depend on the weather; try pouring concrete in February.
- Require curing time.
- Often involve more excavation and restoration.
At GAMCON, we almost always recommend helical piles over traditional concrete, whether you’re building a deck or underpinning a foundation. For more detail, see our guide on Helical Anchors vs. Concrete Anchors: Pros & Cons.
How Many Piles Will You Need?
Here are some common scenarios:
- 10×10 deck: ~4 piles
- 12×16 deck: ~5–6 piles
- Sunroom or addition: ~8–12 piles
Of course, factors like multi-level designs or heavier load-bearing walls increase that number.
Not sure how many your project needs? GAMCON offers free on-site assessments so you’re not left guessing or overspending.

Toronto Buyer’s Checklist
Choosing the right contractor is half the battle. Before signing anything, ask for:
- Full pile specifications (shaft size, helix size, number of helices)
- Torque report (P = Kt × T) proving load capacity
- Extension pricing per foot
- Bracket type (adjustable or fixed)
- Mobilization and minimum charges
- Permit handling (Toronto building permits, TRCA approvals)
- Warranty coverage and engineer certification
- Estimated installation timeline
This way, you’ll avoid those “surprise” costs that make budgets balloon.
Example Pricing Scenarios (Toronto)
Let’s crunch some real-world numbers:
- Scenario 1: Small downtown deck, 6 piles → $2,100–$3,000 total
- Scenario 2: Sunroom addition, 10 piles + engineering → $4,500–$6,500
- Scenario 3: Foundation underpinning, 12 piles + TRCA permit → $10,000+

FAQs
Do I need a permit for screw piles in Toronto?
Yes, most projects require a Toronto building permit, and if you’re near a ravine or waterfront, a TRCA permit as well.
How deep do helical piles go?
In Toronto, expect a minimum of 1.2m, though depth varies with soil conditions and load requirements.
Are helical piles cheaper than concrete footings?
They can be. While the per-pile cost might look higher, you save on excavation, restoration, and time.
Can I install screw piles in winter?
Yes! That’s one of the biggest advantages. Frozen ground isn’t a dealbreaker for screw piles.
Do I need a TRCA permit near ravines or waterfront properties?
Yes, if you’re in a regulated area. Fees typically run $240–$535.
