Wood Fence Cost in Ontario: Cedar, PT, and Board-on-Board

Planning a wood fence in Ontario? You're looking at $30-50 per linear foot for pressure-treated and $40-60 per linear foot for cedar, both installed. Those numbers include materials, labour, and basic post installation—but the final price depends on height, style, soil conditions, and whether you need a permit.

Here's what drives wood fence costs in Ontario and how to budget for your project.

Pressure-Treated vs Cedar: Price Breakdown

The two most common wood fence materials in Ontario have different upfront costs and lifespans.

Pressure-Treated Pine

• Materials only: $12-18/linear foot
• Installed: $30-50/linear foot
• Lifespan: 15-20 years with proper maintenance
• Best for: Budget-conscious projects, rear yard privacy fences

Cedar

• Materials only: $18-28/linear foot
• Installed: $40-60/linear foot
• Lifespan: 25-30 years, naturally rot-resistant
• Best for: Front yards, premium aesthetics, homeowners avoiding chemical treatments

Pressure-treated (PT) lumber costs less because it's widely available and fast-growing. Cedar costs more because it's naturally durable, lighter weight, and doesn't require chemical preservatives. In Ontario's freeze-thaw climate, both perform well if installed correctly—the key difference is maintenance frequency and aesthetic preference.

For a 150-foot privacy fence, expect to pay:

• Pressure-treated: $4,500-7,500 installed
• Cedar: $6,000-9,000 installed

Fence Style Costs: Picket, Privacy, and Board-on-Board

Style matters more than most homeowners expect. A 6-foot privacy fence uses significantly more lumber than a 4-foot picket fence, and board-on-board designs require overlapping boards that increase material costs.

| Fence Style | Material Cost (per linear foot) | Installed Cost (per linear foot) |

|-------------|--------------------------------|----------------------------------|

| 3-4 ft picket fence | $8-14 | $25-40 |

| 6 ft privacy (standard) | $12-20 | $30-55 |

| Board-on-board | $15-25 | $40-65 |

| Shadowbox | $14-22 | $35-60 |

| Horizontal slat | $16-28 | $45-70 |

Board-on-board (also called "good neighbour" fence) alternates boards on both sides of the rails, creating a finished look from both sides and better wind resistance. It uses roughly 30% more lumber than standard privacy fencing, which explains the higher cost.

Shadowbox staggers boards with gaps, allowing airflow while maintaining privacy. It's popular in Ontario because it handles wind load better than solid privacy panels and sheds snow more easily.

If you're building a fence that needs to look finished from both sides—say, along a shared property line—board-on-board is worth the extra cost. For rear yards where only one side matters, standard privacy fencing saves money.

What's Included in Installed Pricing

When contractors quote "$45 per linear foot installed," here's what that typically covers:

• Lumber (posts, rails, pickets)
• Hardware (screws, brackets, post caps)
• Labour (digging, assembly, installation)
• Post installation (concrete footings or gravel base)
• Basic gate (one standard 3-4 ft gate included in most quotes)

Not usually included:

• Fence permit ($50-200, varies by municipality)
• Gate hardware upgrades (self-closing hinges, locks)
• Removal and disposal of old fence ($3-8/linear foot)
• Grading or sloped terrain adjustments
• Staining or sealing (add $2-5/linear foot)

Always ask for an itemized quote. Some contractors bury permit fees or gravel base costs in vague line items. See our deck quote line items guide for how to read contractor estimates—the same principles apply to fencing.

Fence Height and Ontario Bylaws

Height directly affects cost because taller fences need more lumber, deeper post holes, and stronger bracing.

Typical Ontario fence height limits:

• Front yard: 3-4 feet maximum
• Side and rear yard: 6 feet maximum
• Corner lots: 3 feet within the "sight triangle" (to preserve driver visibility)

Kitchener, Waterloo, and Cambridge follow these general rules, but each municipality has specific setback and height regulations. A 6-foot fence costs roughly 40% more than a 4-foot fence due to additional picket length and deeper footings.

If you're planning a fence taller than 6 feet—rare but sometimes allowed with variances—expect engineering requirements and significantly higher costs. Most residential projects stick to 6 feet to avoid permit complications.

Check height limits and setback rules before getting quotes. Our fence setback guide for KWC covers property line requirements.

Post Spacing and Footing Costs

Standard fence posts are spaced 8 feet apart for privacy fences and 6-8 feet apart for picket fences. Closer spacing increases stability but adds cost.

Post installation methods in Ontario:

• Gravel base: $8-12 per post (drainage-friendly, easier to adjust)
• Concrete footings: $15-25 per post (more stable, required for gates and heavy fence styles)

In Ontario's clay-heavy soil—common in Kitchener-Waterloo-Cambridge—concrete footings help prevent frost heave. The frost line sits around 4 feet deep, so posts need to extend below that to avoid winter shifting. Contractors typically dig 48 inches deep for fence posts, deeper than the casual DIYer expects.

For a 100-foot fence with posts every 8 feet, you're looking at 13 posts. If each post needs a concrete footing at $20, that's $260 just for post installation—often buried in the "per linear foot" pricing but worth understanding.

Cedar vs Pressure-Treated: Maintenance Costs Over Time

Upfront cost is only part of the equation. Factor in maintenance over the fence's lifespan.

Pressure-Treated Maintenance:

• Year 1: Let lumber dry 6-12 months before staining
• Every 2-3 years: Reapply stain or sealant ($2-4/linear foot if hiring out)
• Years 10-15: Expect to replace rotted pickets or rails

Cedar Maintenance:

• Optional staining: Cedar weathers to silver-grey naturally; staining is cosmetic
• Every 3-5 years: Reapply sealant if you want to preserve colour
• Years 20+: Replace pickets as needed, but cedar resists rot longer

Over 20 years, pressure-treated fencing may require $1,500-3,000 in staining and repairs for a 150-foot fence. Cedar requires less frequent maintenance but costs more upfront. If you plan to stay in your home long-term, cedar's lower maintenance burden often justifies the higher initial cost.

DIY vs Hiring a Contractor

Building your own fence saves on labour—typically 50-60% of the installed cost—but requires tools, time, and comfort working with uneven terrain.

DIY costs (materials only) for 100-foot privacy fence:

• Pressure-treated: $1,200-1,800
• Cedar: $1,800-2,800

Tools you'll need:

• Post hole digger or auger rental ($40-80/day)
• Level, string line, tape measure
• Circular saw or miter saw
• Drill and impact driver
• Concrete mixer (if using concrete footings)

Time estimate: Expect 2-3 full weekends for a 100-foot fence if you're working solo. Digging post holes in Ontario clay is slow, physical work. If you've never built a fence, your first project will take longer than you anticipate.

Hiring a contractor makes sense if:

• You're working with sloped or uneven terrain
• Your municipality requires a permit and inspections
• You want the job done in 2-3 days instead of 2-3 weekends
• You lack tools or experience setting posts level

For complex projects—like fences on steep grades or corner lots with sight triangle rules—hiring a pro avoids costly mistakes.

Permits for Wood Fences in Ontario

Most municipalities in Ontario require a permit for fences over a certain height or within specific setbacks.

Kitchener fence permit:

• Required for fences over 6 feet or within setback zones
• Cost: $50-100
• Processing time: 2-4 weeks

Waterloo fence permit:

• Required for fences over 4 feet in front yards or 6 feet in rear yards
• Cost: $75-150
• Processing time: 2-3 weeks

Cambridge fence permit:

• Required for fences within 3 feet of property line in some zones
• Cost: $50-200
• Processing time: 2-4 weeks

Check your municipal bylaws before building. Installing a fence without a permit can result in fines and forced removal. Our fence permit guides for Kitchener, Waterloo, and Cambridge cover application steps.

Hidden Costs to Budget For

Beyond the per-linear-foot price, watch for these extras:

Old fence removal: $3-8/linear foot. Contractors charge separately for demolition and disposal. If you're replacing an existing fence, factor this in.

Gates: A basic 4-foot gate is often included, but double gates or custom widths cost $200-500 extra. Self-closing hinges and locking hardware add $50-150 per gate.

Staining: Most contractors install raw wood. If you want a stained finish, add $2-5/linear foot for labour and materials.

Sloped terrain: Fences on slopes require stepped or raked designs. Raked fences (pickets follow the slope) cost 10-20% more due to custom cutting and layout complexity.

Corner bracing: Corner posts and gate posts need diagonal bracing for stability. Contractors usually include this, but confirm it's part of the quote.

Wood Fence Cost by Project Size

Here's what typical Ontario projects cost in 2026, fully installed:

50-foot privacy fence (6 ft tall, PT):

• Material: $600-900
• Installed: $1,500-2,500

100-foot privacy fence (6 ft tall, cedar):

• Material: $1,800-2,800
• Installed: $4,000-6,000

200-foot board-on-board fence (6 ft tall, cedar):

• Material: $3,600-5,600
• Installed: $8,000-13,000

Longer runs reduce the per-foot cost slightly because contractors spread mobilization and setup over more linear footage. A 200-foot project might come in at $38/foot instead of $45/foot for a 50-foot run.

How to Get Accurate Quotes

Don't accept vague "$40 per foot" estimates. Request itemized quotes that break down:

• Linear footage
• Fence height and style
• Material type (species, grade)
• Post spacing and footing method
• Gate quantity and hardware
• Permit costs
• Removal of existing fence (if applicable)
• Staining or sealing
• Payment schedule

Get at least three quotes from local contractors. Prices vary by 20-30% depending on workload, material sourcing, and contractor experience. Our deck quote checklist applies to fencing—ask the same questions about warranties, timeline, and what's included.

Common Questions

How much does a 6-foot privacy fence cost per linear foot in Ontario?

$30-55 per linear foot installed, depending on material. Pressure-treated runs $30-50/foot, cedar runs $40-60/foot. Board-on-board or shadowbox styles add $5-15/foot due to extra lumber and labour.

Is cedar worth the extra cost over pressure-treated?

Yes, if you're staying in your home long-term. Cedar lasts 25-30 years with minimal maintenance, while pressure-treated needs staining every 2-3 years and typically lasts 15-20 years. Cedar's natural rot resistance and lower chemical exposure appeal to many homeowners, especially for front yards or areas near gardens.

Do I need a permit for a wood fence in Kitchener-Waterloo-Cambridge?

It depends on height and location. Most municipalities require permits for fences over 6 feet tall or within setback zones (often 3 feet from property lines). Front yard fences typically need permits if over 3-4 feet. Check your local bylaws—building without a permit can result in fines and forced removal.

How deep should fence posts be in Ontario?

At least 4 feet deep to sit below the frost line. Ontario's frost line is approximately 4 feet, and posts shallower than this can shift during freeze-thaw cycles. Most contractors dig 48 inches deep and use concrete or gravel for stability. Posts supporting gates or on slopes may need to go deeper.

What's the difference between board-on-board and standard privacy fencing?

Board-on-board alternates pickets on both sides of the rails, creating a finished look from both sides and better wind resistance. Standard privacy fencing attaches all pickets to one side. Board-on-board uses about 30% more lumber, which adds $10-15/linear foot to the cost, but it's ideal for shared property lines where both neighbours see the fence.
