As a 2026 planning estimate, residential sewer line work in Canada typically works out to about $180 to $300 CAD per foot ($600–$1,000 per metre) for shallow open-cut replacement under soft ground, $300 to $600 per foot when deep or under hard surfaces, and roughly $150 to $400 per foot for lining or bursting before setup and pits. Short runs cost more per foot.
- A per-foot rate only means something when you know what it leaves out: setup, pits, permits, the city connection and restoration usually sit outside it.
- Fixed costs make short runs expensive per foot; a 6 m job can cost half as much again per metre as a 20 m job.
- Convert everything to one unit before comparing: 1 metre is 3.28 feet, and 1 foot is 0.3048 metres.
- Per-foot figures on American websites are in US dollars and reflect different markets; use Canadian ranges for Canadian quotes.
01 /What does a sewer line cost per foot in Canada?
Per-foot and per-metre figures describe only the variable part of a sewer job: the cost of digging, laying, lining or bursting each additional length of pipe. In 2026 planning terms, Canadian quotes for residential laterals generally imply the rates below once setup, access pits, permits, the municipal connection and surface restoration are taken out.
| Method and conditions | Per metre | Per foot | Usually priced outside the rate |
|---|---|---|---|
| Open-cut, under 2 m deep, lawn or garden | $600–$1,000 | $180–$300 | Permit, cleanout, city connection, sod or seed |
| Open-cut, 2.5 m or deeper, or under concrete or asphalt | $1,000–$2,000 | $300–$600 | Permit, city connection, hard-surface rebuild |
| Cured-in-place lining (CIPP), full lateral | $500–$1,200 | $150–$365 | Setup, cleaning, reinstatements, any access pit |
| Pipe bursting with HDPE | $550–$1,300 | $170–$400 | Setup, launch and receiving pits, pit restoration |
| Extra length added mid-job (change order) | $500–$2,000 | $150–$600 | Depends on method and depth; get it in writing |
Treat these as the middle layer of a quote. A contractor who says "about $250 a foot" on the phone is usually describing this layer only, and the finished invoice will add fixed items on top. Ask which items the rate includes before you multiply it by the length of your line.
02 /Why is the per-foot price higher on short runs?
Short runs cost more per foot because every sewer job carries fixed costs that do not shrink with length. Mobilising an excavator or a lining rig, arranging locates, pulling a permit, digging the connection at each end and running a camera before and after cost roughly the same for 6 m of pipe as for 20 m.
| Length replaced | Fixed costs (assumed) | Variable at $700/m | Total | Effective per metre | Effective per foot |
|---|---|---|---|---|---|
| 6 m (20 ft) | $4,000 | $4,200 | $8,200 | $1,367 | $417 |
| 12 m (39 ft) | $4,000 | $8,400 | $12,400 | $1,033 | $315 |
| 20 m (66 ft) | $4,000 | $14,000 | $18,000 | $900 | $274 |
| 30 m (98 ft) | $4,000 | $21,000 | $25,000 | $833 | $254 |
The same arithmetic explains why a spot repair on one defect often looks expensive per foot. A single dig to replace 2 m of pipe carries almost the whole fixed cost of a replacement, so its effective rate can reach several thousand dollars per metre even when the total is modest. That is not overcharging. It is the reason to compare totals for equal scope, and to compare rates only between quotes of similar length. See sewer line repair cost for spot-repair totals.
A per-foot rate is a comparison tool, not a price.
03 /What makes the per-foot rate rise or fall?
Depth and surface move the rate most, followed by soil, access and season. Each one changes how many hours a crew and machine spend on every metre of trench.
| Driver | Effect on each metre | Typical trigger |
|---|---|---|
| Depth | More excavation, shoring or sloping, and more backfill per metre | Laterals below about 1.5 m, common where frost is deep |
| Surface | Removal and rebuild priced per square metre over the trench | Concrete drives, pavers, asphalt, landscaped beds |
| Soil and water | Slower digging, dewatering, imported bedding | Wet clay, high water table, cobbles or rock |
| Access | Smaller machines or hand digging slow the whole run | Narrow side yards, rear lanes, basement work |
| Pipe diameter | Larger pipe, fittings and bedding cost more per metre | 150 mm (6 in) laterals on larger or multi-unit buildings |
| Season | Frost removal and heating slow excavation | Winter digs in colder provinces |
For trenchless work, depth matters less to the per-metre rate and more to the cost of each pit. A lining crew pulling from an existing cleanout 2.5 m down has much the same per-metre cost as one working at 1.5 m; a bursting crew digging two 2.5 m pits pays for the extra depth twice. The method-level detail is in trenchless lining vs pipe bursting cost, with deeper breakdowns in sewer pipe lining cost and pipe bursting cost.
04 /How do I measure my sewer line length?
Measure the length along the pipe's actual route, because that is what a contractor prices. The most reliable number comes from a recorded camera inspection with a distance counter; a tape measure across the yard is only a first estimate.
- Start from the camera report
The footage counter shows distance from the access point to the main or to where the camera stopped. Note the access point, because a basement cleanout adds the length under the floor to the outside run.
- Find the property line
Your survey or real property report shows it. Measure from the front foundation wall to that line so you know how much of the pipe is on your side.
- Add the bends
A lateral that swings around a tree or a garage is longer than the straight-line distance. The sonde locate from the camera visit shows the true route on the ground.
- Note the depth at both ends
Depth at the house and at the property line sets the depth tier for the whole run. Ask the camera operator to record both.
- Convert once
Pick metres or feet and convert every quote to the same unit: multiply metres by 3.28 for feet, or feet by 0.3048 for metres.
With length and depth known, you can check any per-foot figure in minutes. The sewer camera inspection cost guide lists what a report should record so the numbers are there when you need them.
05 /How do I check a quote's per-foot rate?
Strip the fixed items out of the total, divide what remains by the length in scope, and compare the result with the range for the same method and depth. A rate far outside the range is a question for the contractor, not a verdict on the contractor.
- Write down the quote total before tax.
- Subtract permits, the municipal connection, the cleanout, surface restoration and any access pits that are priced separately.
- Divide the remainder by the metres (or feet) of pipe being replaced or lined.
- Compare the result with the table above for the method and depth in the quote.
- Repeat for every quote, using the same length for each if they describe the same run.
| Step | Quote A (open-cut) | Quote B (lining) |
|---|---|---|
| Total before tax | $19,400 | $17,300 |
| Less permit | $350 | $350 |
| Less cleanout | $1,100 | Existing cleanout used |
| Less restoration | $2,200 | None needed |
| Less setup, cleaning and reinstatements | Built into the trench price | $3,100 |
| Remainder for pipe work | $15,750 | $13,850 |
| Length | 18 m (59 ft) | 18 m (59 ft) |
| Implied rate | $875/m ($267/ft) | $769/m ($235/ft) |
Both rates sit inside their typical bands, so neither quote looks padded or stripped of work. The decision then turns on scope: whether the defects on the footage suit lining, and what the finished surface looks like. The sewer cost estimator runs the same check with your length, depth and surface, and the quote comparison worksheet lines up what each quote includes side by side.
06 /What should a per-metre unit rate in a contract look like?
A good contract uses a per-metre rate in one specific place: pricing extra length that nobody could see before digging. If the camera stopped at 16 m and the real run turns out to be 19 m, the extra 3 m should be billed at a rate written into the quote, not negotiated with the trench open.
- State the unit. Per metre or per foot, and which one the invoice will use.
- State the conditions. The rate for extra length at the same depth and surface as the quoted run, with a separate rate or approval step if conditions change.
- Cap the surprise. A clause saying no extra length is added without your written approval of the metres and the total.
- Match the method. An extra-length rate for lining should not be applied to an open-cut section, and the reverse.
Compare those extra-length rates across quotes as carefully as the totals. A low total paired with a high extra-length rate can overtake a higher total once the line proves longer than the camera showed. The 15 questions to ask include the wording to request.
07 /Why do US per-foot prices look different?
Most per-foot sewer prices published online are American, in US dollars, and drawn from US labour, permit and restoration markets. They can sit above or below Canadian quotes for reasons that have nothing to do with your line: shallower frost depths across much of the southern United States, different excavation rules, different municipal connection policies and a different currency.
Use them only to understand structure — fixed costs plus a per-length rate — never as a benchmark for a Canadian quote. Figures on this site are in Canadian dollars and framed for Canadian conditions, including deep frost-protected laterals on the Prairies. City-to-city differences inside Canada are covered in sewer line replacement cost by city.
Once your length and depth are known, request quotes that state them, so every contractor prices the same run.
FAQQuestions people ask
How much does a sewer line cost per foot to replace?
As a 2026 planning estimate, open-cut replacement in Canada typically implies about $180 to $300 CAD per foot for shallow runs under soft ground and $300 to $600 per foot for deep runs or runs under hard surfaces, before permits, the city connection and restoration.
What is the cost per foot for trenchless sewer repair?
Lining typically implies about $150 to $365 CAD per foot and pipe bursting about $170 to $400 per foot, as 2026 planning estimates, with setup, cleaning, reinstatements and access pits priced on top.
Why was I quoted a higher per-foot rate than my neighbour?
The usual reasons are a shorter run carrying the same fixed costs, a deeper line, a harder surface over the pipe, or a quote that folds restoration and permits into the rate. Compare what each rate includes before comparing the numbers.
Should a sewer quote be priced per foot or as a lump sum?
Either works if the scope is clear. A lump sum with a stated length lets you calculate the rate yourself, and a written per-metre rate for extra length protects you if the line turns out longer than expected.
How do I convert a per-foot sewer price to per metre?
Multiply the per-foot price by 3.28 to get the per-metre price, or divide a per-metre price by 3.28 to get per foot. For example, $250 per foot is about $820 per metre.
Does the per-foot price include the connection to the city sewer?
Usually not. Work at or past the property line, road or boulevard cuts and municipal fees are normally priced separately. Confirm with your municipality whether that portion is your responsibility.
