What Artificial Grass Costs in Canada — And How Deep the Base Has to Be

Why a Canadian turf calculator is not an American one with a different currency symbol

Above ground a Canadian synthetic lawn and an American one are the same product. Below it they are not the same job. Artificial grass is a permeable surface sitting on compacted aggregate, which means every drop of water that falls on it has to leave through that base. In a frost-free market the consequence of a marginal base is a puddle. Here the consequence is an ice lens that lifts the base, after which the turf heaves and buckles and never sits flat again — and a Montréal landscaper writing in March 2026 says do-it-yourself installations commonly fail within one or two winters for exactly that reason.

The second Canadian mechanic is the calendar. The base has to be excavated to depth, graded to a fall and compacted in layers, and none of those three things can be done properly through frozen ground — so the Canadian installation window is materially shorter than the one a US turf calculator implicitly assumes. That is reported on this page and never priced, because no Canadian source read publishes a seasonal differential of any kind, and inventing one would be worse than leaving the gap.

The third is labour, which moves the whole job through Job Bank's economic-region wage medians for the construction trades rather than through an invented city premium — a federal government wage report, damped by a published labour share. It is the only government figure on this route, and that is worth saying plainly: no Canadian government body and no Canadian landscape-industry association publishes an installed synthetic turf price, so every cost band here is a dated Canadian commercial publisher's.

The base-depth disagreement, and what the extra stone actually costs

Two Canadian publishers specify a base depth and they do not specify the same one. A national Canadian supplier writing on 14 January 2026 puts crushed stone at 2–3 inches with a drainage fall of about 0.5%. An Ontario landscaper writing on 26 February 2026 puts excavation at 3–4 inches over 3/4″ to 1/4″ drain rock. 3 inches is the only depth both of them endorse — the top of one range and the bottom of the other. A third Canadian publisher, in Montréal, gives no number at all and says only that the base must be deep enough to handle freeze-thaw movement, which is an honest refusal rather than an omission.

The useful part is how small the money is. Aggregate volume is pure geometry — area × depth ÷ 12 ÷ 27 — and at the published Canadian supply rate of C$25–C$40 per cubic yard, a 20 × 20 foot lawn (400 square feet) takes 2.47 cubic yards at 2″ and 4.94 cubic yards at 4″ — which is C$61.73–C$98.77 of stone against C$123.46–C$197.53. Going from the shallow publisher's floor to the deep publisher's ceiling exactly doubles the aggregate and costs on the order of C$61.73–C$98.77 more. That is the price of the entire Canadian base-depth argument, and it is smaller than most people expect.

Which tells you where the base money really goes. The published base-work band is C$1.50–C$3.00 per square foot, or C$600–C$1,200 over this lawn, and the stone in it is a small fraction of that. The rest is excavation, grading a fall so water leaves, and compaction in layers — labour, and the labour is what decides whether the lawn survives ten Canadian winters. This is why the calculator reports the stone separately rather than folding it in, and why it does not add it to the total: the base-work band is published as “Gravel/Stone”, so the aggregate is already inside it and counting it twice would be an error.

The cost ladder, in C$

The three rows that scale with area are one Ontario publisher's own table, read on one page on one date, rather than the cheapest row from each of several. That is the rule this site works under: a level comes from a publisher and a difference comes from inside that publisher's own table.

And everything else that goes into the job:

• Aggregate base — supply, place, grade and compact — C$1.50–C$3.00 per square foot. The publisher lists this as "Gravel/Stone" inside a wider base-preparation band of C$3–C$12 per square foot. It is overwhelmingly LABOUR rather than stone: the raw aggregate for this job, priced separately below at a Canadian supply rate per cubic yard, comes to well under a dollar a square foot. What you are paying for is excavation to depth, a graded fall so water leaves, and compaction in layers. That is also the line that decides whether the lawn survives ten Canadian winters, which is why this calculator makes its depth an input.
• Turf installation labour — C$3.00–C$10.00 per square foot. Published as C$3 to C$10 per square foot "depending on site complexity" — seaming, cutting around beds and hard edges, stretching, nailing or stapling the perimeter, and brushing the infill in. The band is wide because that phrase is doing a lot of work: a clean rectangle of open lawn is at the bottom of it and a terraced yard full of curves and tree roots is at the top. A second Canadian publisher puts the same labour at C$5–C$15 and a third at C$2–C$6, so the disagreement is wide too, and all three are on the page.
• Strip existing sod, excavate and dispose — C$1.00–C$3.00 per square foot. Published by the source as CAD 1 to 3 dollars per square foot "or more" for sod removal and debris disposal — C$1–C$3 here, relabelled with an explicit C$ so nothing on a Canadian page can be read as US dollars; the "or more" is not modelled. This is the one line that is NOT scaled by your chosen base depth, and the refusal is deliberate: the publisher prices it per square foot with no depth term in it, so multiplying it by a depth ratio would invent a number. A deeper base does mean more spoil to haul away, and the honest way to say so is in words rather than in a decimal point.
• Professional infill service — C$300–C$800, per application, flat. Published as a flat C$300 to C$800 per application rather than per square foot, which is why this calculator charges it flat. Infill is the sand or coated-sand ballast brushed down between the blades; it holds the turf flat, keeps the fibres upright and adds the weight that stops wind lifting an edge. A second Canadian publisher does price it per square foot, at C$0.50–C$2.50, which over an ordinary back lawn lands in a similar place — that cross-check is on the page.
• Bender-board perimeter edging — C$2.00 per linear foot. A SINGLE published figure rather than a band — C$2.00 per linear foot — so it is rendered as one number and no range is invented around it. Edging is what the turf perimeter is fastened to and what stops the aggregate base migrating out into the beds; in a freeze-thaw climate the edge is where lifting starts, so it is not a cosmetic line. Over a 20 × 20 foot lawn's 80 linear feet that is C$160.
• Crusher chip aggregate — C$25–C$40 per cubic yard. Reported against your chosen depth and never added to the total, because the base-work band above is published as “Gravel/Stone” and already contains it.

Four Canadian publishers, and they do not agree

Every one of these is a Canadian publisher's own all-in statement about an installed synthetic lawn, in Canadian dollars, read on 13 September 2026. They are shown side by side rather than averaged into a figure none of them stated — and at the top end they differ by nearly a factor of two, which is itself the most honest thing this page can tell you about the reliability of any single number in this market.

One methodological uncertainty stated plainly, because it is the biggest one on this page. The ladder publisher lists turf material, base preparation and installation labour under separate headings, so this calculator adds them — and then that same publisher states its own all-in figure as C$8 to C$18 per square foot installed, which the top of the added components can exceed. That is an internal inconsistency inside one publisher rather than an error here, and it is shown rather than smoothed: the published all-in band is printed on the results panel next to the computed one, alongside two other Canadian publishers' all-in bands, so you can see all four at once. If you are comparing this estimate against a quote, the thing to establish first is whether the quote includes excavation and disposal of the old lawn, because that single line is C$1 to C$3 a square foot and it is the one most often quoted separately.

Freeze-thaw, in one place

This is the Canadian half of a synthetic lawn and it is entirely underneath it. Artificial turf is a permeable surface sitting on compacted aggregate, so the water that falls on it has to leave through that base. Where it cannot, it sits there and it freezes, and the ice lens lifts the base — a Montréal landscaper writing in March 2026 states it directly: "A proper aggregate base allows water to drain before freezing, which prevents the turf from heaving or buckling", and "In Montreal, this base needs to be deep enough to handle freeze-thaw movement." The same publisher says installations that skip adequate base depth fail under freeze-thaw cycling, and that do-it-yourself installations commonly fail within one or two winters for that reason. Note what that means about where the money is: the turf carpet is the visible part and the cheap part, and the base is the part that decides whether you are doing this again in three years. It is also why the two Canadian publishers who do specify a depth are worth reading against each other rather than averaging — one says 2 to 3 inches, the other 3 to 4.

What this calculator refuses to tell you

It will not charge you more for installing in a shorter season. The Canadian installation season is shorter than a synthetic-turf calculator written for a frost-free market would assume, and this page reports that without pricing it. The reason is mechanical rather than about the turf: the base has to be excavated to depth, graded to a fall and compacted in layers, and none of those three things can be done properly through frozen ground. The finished lawn is genuinely indifferent to Canadian winter — every Canadian source read agrees the fibres do not crack or degrade in the cold — but the installation is not. What could NOT be established is any figure. The Canadian installer page read on the subject urges getting the work done "before the snow arrives" and gives no month, no temperature limit and no price consequence; no Canadian source read publishes a seasonal price differential, a shoulder-season discount or a winter surcharge. So no seasonal adjustment of any kind is applied here, and if your quote carries one, it is your contractor's number rather than a published Canadian one. The practical advice that survives the lack of a figure: book the base work for the open ground months, and expect the spring queue to be longer than the autumn one.

It will not scale the sod-removal line by your base depth. A deeper base genuinely does mean more spoil to haul away, and the honest way to say so is in words: the published Canadian figure is per square foot with no depth term in it, so multiplying it by a depth ratio would invent the number rather than source it.

It will not price a permit, and it does not model GST, HST or PST. Permits are municipal and usually scale with declared value; none was read for any city on this list, so a figure here would be a guess wearing your city's name.

And it will not tell you when artificial grass pays for itself against a real lawn. Canadian turf marketing puts that at a number of years through avoided mowing, watering and fertiliser. Nobody read for this build publishes a Canadian maintenance cost series behind that claim, and repeating one with a decimal point attached would be worse than leaving it out. Width and length are both asked for rather than a single area figure, because two different prices need two different measurements: the turf, base and labour are priced per SQUARE foot and the edging per LINEAR foot. A calculator that took only an area would have to guess a shape to get a perimeter, and a long narrow strip down the side of a house has far more edge per square foot than a square back lawn. The assumption that remains is that the area is a rectangle with all four sides edged — a curved bed line, a lawn that runs up against an existing patio or a shape with a cut-out will differ, and since edging is priced per linear foot you can redo that one line in a single multiplication.

Next steps

A lawn is rarely the only thing being priced in a Canadian back yard. The Canadian deck building cost calculator prices the other outdoor build from the same starting point — how deep your own municipality makes you go below frost — and the Canadian eavestrough installation cost calculator covers where the roof water goes before it ever reaches the ground, which is worth settling before you put a permeable surface next to the house. For the wider job, the Canadian home renovation cost calculator puts it all in CAD with the provincial sales tax on top, and if the work is being financed rather than saved for, the Canadian HELOC calculator shows what is actually borrowable against the house under Canadian lending limits.
