How Many Lawn Signs Does a Campaign Actually Need?

Ask five campaign managers how many lawn signs to order and you will get five numbers, all delivered with total confidence, none of them derived from anything. The number is a calculation, and it is one almost nobody sits down and does. It depends on how many doors your team will physically reach, how many of those say yes, how many genuinely high-traffic spots exist in your area, and how many signs the weather and the world will take from you before voting day.

That last input is the one campaigns forget. A lawn sign is not a thing you buy once and own; it is a thing you deploy, lose and replace across a season legally capped, in Ottawa, at 45 days on private property — a limit each municipality sets for itself, so check yours. Plan for the signs you intend to place, then plan, in writing, for the ones that will not survive.

What follows is that arithmetic, every assumption stated out loud so you can swap our guesses for your own. Nothing here is a rule. It is a model, and it sharpens the moment you replace the placeholder rates with real canvassing data.

Every campaign sign order, from a first council run to a city-wide mayoral campaign, is the same four lines added together:

• Line 1 — supporter lawns. Signs on the property of people who asked for one. Falls out of canvassing arithmetic.
• Line 2 — high-visibility placements. Signs positioned for traffic rather than to signal a household. Falls out of a map.
• Line 3 — attrition allowance. A percentage on top of lines 1 and 2, because some of what you plant will be gone by voting day.
• Line 4 — late-request reserve. A smaller percentage held on a shelf for requests arriving in the last ten days.

Notice what is absent: a fixed percentage of the ward population, or the number the campaign down the street ordered. Population sets the ceiling; your volunteer hours set the actual number. Mixing those up is how a campaign ends up with four hundred signs in a garage in October.

Start with households, then cut relentlessly. Take a ward of 15,000 households— use your own figure, the method is what matters. A team canvassing three evenings a week plus weekend mornings over an eight-week campaign realistically reaches 3,500 to 5,000 doors, counting each address once.

Roughly one in three answers, giving 1,150 to 1,650 actual conversations. Of the people who open the door and are friendly, a realistic planning band is that 8–12% accept a sign. Run it at both ends:

• Low end — 3,500 doors × one-in-three answering = 1,150 conversations × 8% = about 90 supporter lawns
• High end — 5,000 doors × one-in-three answering = 1,650 conversations × 12% = about 200 supporter lawns

So the supporter-lawn line for that ward is 90–200, and the width of that range is the honest part of it.

Then make the correction that matters more than any rate above: strike out the households that structurally cannot host a sign. An apartment tower with 200 units has 200 doors and zero lawns. In a high-rise-heavy ward, half your door count cannot say yes no matter how good your volunteers are, so a campaign budgeting off raw household counts over-orders badly. In a suburban ward of detached homes, almost every door is a candidate.

One discipline point rather than a maths point: log every yes as an address, immediately, in one shared list. The quantity you order should come from a list that exists, not a feeling about how the door-knocking is going.

The second line has nothing to do with canvassing conversion, which is why it is counted separately. A supporter lawn on a quiet crescent is seen by the eleven households on that crescent; a sign on a corner lot at an arterial intersection is seen by thousands of cars a day. Campaigns under-count the second kind because it does not arrive through the canvassing pipeline.

Build this line by driving or tracing your area and listing the categories:

• Corner lots on arterial roadswith a willing owner — the highest-value placement there is.
• Long private frontage along a commuter route, where one property faces thousands of morning drivers.
• Commercial and small-business property, with the owner's explicit permission, ideally in writing.
• Public property and city road allowance, where and when the municipality permits it — in Ottawa that window opens later than the private-property one.

Two techniques change the count. Double-sided printingmakes one corner placement read from both directions of traffic, so a corner lot needs one sign rather than two angled ones — precisely where the cost of printing both sides earns itself back. And at your ten or fifteen best locations a cluster of two or three signs reads as momentum in a way a lone sign does not, so budget those spots at double.

For a single ward, a realistic list is 30–60 worthwhile locations, doubled at the best ten to fifteen, which is 40–75 signs on line 2. One caution before you fall in love with a corner: in Ottawa a sign on private property may not sit within three metres of an intersection, so the perfect spot is often three metres back from where you pictured it. For which size actually reads at speed, our lawn sign size guide settles it with measurements rather than opinions.

This is the line that turns a well-planned order into an under-order. Between the day your signs go up and the day they come down you will lose some. Not might — will. In Ottawa that span runs from September 11 on private property to a removal deadline three days after voting day — a hostile stretch of weather for a light sheet of corrugated plastic on two wire legs.

What takes them:

• Wind.Coroplast is a sail. An 18×24 sign on a wire H-stake in open suburban frontage catches gusts all season; the stake pulls out or the board bows at the flutes.
• Rain, then frost. Saturated ground will not hold a wire stake, and after the first hard freeze you cannot easily re-stake what fell over.
• Early snow and plows. Anything near a road edge in an Ottawa October is on borrowed time.
• Theft and vandalism. It happens to every campaign in every race: worth planning for, not worth spending emotional energy on.

A defensible allowance is 15% in a dense urban ward and up to 20% on exposed suburban arterials, applied to lines 1 and 2 combined. Three things pull it down: 6mm board with a gloss UV coatinstead of standard 4mm coroplast where wind is worst, heavier stakes or frames for hard ground, and — the cheapest lever by far — a maintenance route: one volunteer, one evening a week, driving the high-visibility list with a mallet and re-staking what has gone down.

Line 4 is smaller and separate. Sign requests spike in the final ten days as the race gets attention, and with nothing on the shelf you either tell a supporter no or pay for a rush reorder. Hold back about 10% as your own inventory. It is the cheapest insurance in the campaign.

Here is the model run at three scales. We have produced campaign materials for mayoral and city-council campaigns — signs, door hangers and volunteer apparel — and these are the shapes that recur. Every input is an assumption to overwrite with your own.

A. A small, dense urban ward — first council run. 15,000 households, many of them without lawns, a keen but small volunteer team.

• Line 1, supporter lawns: 90–200
• Line 2, mapped high-visibility placements: 40–75
• Subtotal in the ground: 130–275
• Line 3, attrition at 15%: add 20–41
• Line 4, reserve at 10%: add 13–28
• Order range: roughly 175–350 signs

B. A large suburban ward. 22,000 households, nearly all with lawns, longer drives between doors but far more arterial frontage and far more wind.

• Doors reached 5,000–8,000 → about 1,650–2,650 conversations → at 8–12%, supporter lawns of 130–320
• Line 2, mapped placements including roundabout approaches and plaza frontage: 80–140
• Subtotal in the ground: 210–460
• Line 3, attrition at 20% because of exposure: add 42–92
• Line 4, reserve at 10%: add 21–46
• Order range: roughly 300–600 signs

C. A city-wide mayoral run.The model inverts here. You cannot canvass a whole city door to door the way a ward campaign can, so signs come from a volunteer network, a request form on the website and a dedicated placement crew — and you budget ward by ward rather than door by door. Take a city carved into roughly two dozen wards:

• 8 priority wards at 200–350 each: 1,600–2,800
• 16 remaining wards at 75–150 each: 1,200–2,400
• City-wide corridor and major-intersection placements: 150–350
• Subtotal in the ground: 2,950–5,550
• Line 3, attrition at 15–20%: add roughly 440–1,110
• Line 4, reserve at 10%: add roughly 295–555
• Order range: roughly 4,000–7,000 signs

Read those as bands, not targets. If two weeks of canvassing data says your sign-yes rate is 5% rather than 10%, halve line 1 and re-run it. The point of a model is that it responds to evidence.

A sign in a garage is a printed rectangle with no effect on anything. Before you commit to a quantity, convert it into crew-evenings and see whether the schedule survives.

Two volunteers with a truck, a mallet and a clustered address list plant roughly 30–50 signs in an evening. Give the same pair a scattered list across a large suburban ward and it is half that, because the job becomes driving rather than installing. So:

• 300 signs is roughly 6–10 crew-evenings of installation, before any maintenance.
• 600 signs is roughly 12–20 crew-evenings, plus a weekly maintenance route on top.

If the arithmetic says 600 and you have one crew and three free weekends, you do not have a 600-sign campaign. You have a 300-sign campaign and 300 signs in a garage. Sort the installation plan first, then order to it — and remember every sign must also come back out of the ground on a deadline, which is its own set of crew-evenings that nobody budgets for.

Once you have a range, the temptation is to order the bottom of it and reorder later "if we need more." It feels prudent. It is usually the more expensive path, for three reasons.

The per-sign price steps down with quantity. Printing is a setup business: the press is prepared, the board is loaded, the cut is dialled in. That work is charged per run, not per sign, so three runs of 150 means paying setup three times and never reaching the quantity break a single run of 450 reaches.

A reorder costs calendar, the scarcer resource. Our standard turnaround is 2–5 business days after mockup approval and payment— fast, but in a season where an Ottawa sign may legally stand for only 45 days on private property, a reorder in week four eats visibility you cannot buy back.

One run matches itself. Signs printed together on the same board are consistent. Runs weeks apart can differ slightly in colour, and a cluster of three where one is visibly a different red reads as sloppiness at exactly the corner you chose for being the most seen.

None of that argues for over-ordering. It argues for computing the honest total — placements plus attrition plus reserve — and buying it once, holding the reserve as your inventory rather than a future purchase order. If money is tight, the lever is fewer signs printed single-sided, not the same signs split across three invoices. Price both shapes in our free design studio by changing the quantity and watching the per-sign number move, or send the details through the quote form and we will price the breaks for you. Getting the artwork right first is worth an hour — preparing logo files properly prevents the reprint that no schedule has room for.

Quantity and timing are the same decision: the number of days a sign can legally stand is the number of days it can work for you. Ontario municipal elections are held on the fourth Monday of October, which makes voting day Monday, October 26, 2026, with the new council term beginning Sunday, November 15, 2026.

In Ottawa, under by-laws in force since January 1, 2022:

• Private property: a sign may not be placed more than 45 days before voting day — for 2026 that is Friday, September 11, 2026.
• Public property and the city road allowance: 30 days before voting day — for 2026 that is Saturday, September 26, 2026.
• Removal: every election sign must come down within 72 hours after voting day — by Thursday, October 29, 2026.
• Setback: on private property, a sign may not be within three metres of an intersection.

Do the subtraction and the season is smaller than it feels: about six and a half weeks on private property, about four and a bit on road allowance. That short window is what your attrition percentage is spread across.

It also means the print schedule is tighter than it looks. With roughly eight weeks to voting day at the start of September, the first legal day on private property is barely a week and a half out. Count backwards from September 11: 2–5 business days of production after you approve the mockup, and before that, however long your team takes to agree on the wording. The printing is never the slow part. Getting four people to sign off on a headline is.

The governing rules are the Municipal Elections Act, 1996, Ottawa's Temporary Signs on Private Property By-law and the Signs on City Roads By-law (No. 2003-520). Sign complaints in Ottawa go to 3-1-1. Separately, a registered third-party advertiser— not the same thing as a candidate's own campaign — must register with the municipal clerk and must identify itself on its advertising: the registered advertiser's name, the contact information required by the Act, and the municipality where it is registered. If that describes you, build the identification into the artwork from the first draft, not after 400 signs are printed.

These numbers are Ottawa's. Sign rules vary by municipality. Toronto, Mississauga, Gatineau and every other municipality set their own placement dates, setbacks and removal deadlines, and a campaign outside Ottawa must confirm them with its own municipal clerk before ordering anything. We print what a campaign approves — this article is not legal advice, and the clerk's office is the authority. We print for any registered candidate or campaign, without taking a side. Our companion piece on when you can put up election signs in Ontario goes through the timing in more detail, and election lawn signs in Ottawa covers the local specifics.

Signs are one line on the print list. Campaigns pair them with door hangers for the doors nobody answers — door hangers for canvassing runs the same arithmetic — and printed shirts so a team is identifiable at the door, covered in campaign t-shirts and volunteer apparel. The 2026 municipal campaign print checklist puts the season on one page; material, sides and stakes live on our lawn signs page, board choice in coroplast vs PVC, the rest of the range under signs and banners. Once the number is settled, lay the sign out and see it before you pay in the design studio.
