Durham Region Election Sign Rules: Dates, Setbacks and Removal Deadlines (2026)

The short answer

There is no single Durham Region election sign rule. The Region sets requirements for regional roads, each of the eight local municipalities sets its own by-law for everything else, and the dates do not line up. A candidate whose ward straddles a municipal boundary is running two calendars and two sets of penalties at the same time.

The rules that matter fall into four buckets: when a sign is allowed to go up, when it has to come down, how far it has to sit from the curb, and how much the municipality charges you when it has to clean up after you. This guide covers all four for the five cities most Durham campaigns work in, as of August 2026.

When election signs can go up

Display windows in Durham range from seven weeks before voting day to less than four. Clarington measures its window from the first advance voting day rather than from voting day itself, which is why it opens earliest.

Earliest display dates for the October 26, 2026 municipal election, from each municipality's published 2026 material.

That last row catches people out. On a regional road, the Region's by-law defers to whichever date is later — so a sign on a regional road running through Ajax cannot go up in mid-September just because the Region's own 42-day window has opened. Ajax's October 1 date governs.

Putting a sign up early is not a technicality. Municipal enforcement removes non-compliant signs from road allowances without notice, and in Whitby that enforcement includes proactive patrols rather than complaint-driven response only.

When they have to come down

Removal deadlines are where campaigns get hurt, because they are measured in hours after a night nobody wants to spend loading signs into a truck. The tightest deadline in Durham belongs to the Region, and it applies to the busiest, most visible roads a campaign uses.

Removal deadlines after the October 26, 2026 vote. Where two deadlines could apply to the same campaign, the shorter one governs those placements.

Oshawa deserves a note rather than a number. Election Sign By-law 42-2014 is still the operative by-law — By-law 70-2025 amended it in June 2025 to harmonize sign sizes, which it could not have done if the by-law had been repealed and replaced. But a 2023-24 review proposed cutting the display window from 42 days to 25 and the post-election removal deadline from seven days to three, and the publicly available reports and news coverage do not agree on what ultimately landed. Ask the City Clerk, and plan for the tighter deadline.

The practical takeaway for any campaign spanning municipalities: schedule the removal sweep against the shortest deadline that touches your placements, not the most generous one. If you have signs on regional roads anywhere in Durham, that means 48 hours.

What non-compliance actually costs

Several Durham municipalities now hold campaign money against sign compliance. This is the part of the by-law that turns a sloppy placement into a line item.

Published deposits and per-sign removal charges. Amounts confirmed August 2026; fee schedules are updated periodically.

Ajax refunds the balance of the deposit within 60 days of voting day, less deductions. Registered third party advertisers post their own deposits separately from candidates — Clarington requires $250 from an RTPA that plans to use signs, paid from the third party's own campaign account.

Two dozen signs pulled in Ajax is roughly $500 gone, which is the whole deposit. It costs nothing to place them a metre further back.

Where a sign can physically stand

Most signs that get removed are not removed over politics. They are too close to the curb, too tall inside an intersection, cable-tied to a stop sign post, or planted on a traffic island. The Region's requirements for regional roads are the clearest published baseline, and local by-laws are broadly consistent with them:

• At least 1 m back from the curb, or 2 m from the travelled portion where there is no curb
• No more than 1.2 m tall and 0.8 m wide on a regional road
• No more than 0.6 m tall within 20 m of an intersecting road or driveway, to protect sight lines
• Never on a roadway median, traffic island or road shoulder
• Never on a sidewalk, and in Whitby not within 0.3 m of one
• Never attached to a post or pole already carrying an official traffic or road sign
• Not within 500 m of another sign for the same candidate on a regional road

Local by-laws layer more on top. Whitby prohibits signs on Town-owned property and the boulevard beside it, in parks and open space, and anywhere near a voting location including the adjacent boulevard. Clarington bars signs that promote a candidate outside that candidate's own ward, and prohibits placement on public infrastructure. Oshawa's general Sign By-law 72-96 explicitly does not apply to election signs — they are governed by the separate election sign by-law, so do not reason from the rules you may have read about real estate or community event signs.

Ajax adds a safety requirement worth flagging because it is easy to miss and easy to fix: anyone using rebar or reinforcing steel for stakes has to cap every exposed end.

Supporter lawns and private property

A sign on private property needs the consent of the owner, tenant or occupant. That is a by-law requirement, not a courtesy — Clarington writes it into section 5.3 of its election sign by-law and Whitby into section 5.1(a) of by-law 7749-21. In a rental, the occupant's consent is what counts.

Consent is not the end of it. A private-property sign still cannot block a fire exit, a hydrant, an air intake, or emergency access to the building, and it still cannot obstruct a driver's or pedestrian's sight lines. And it still has to come down on the same deadline as everything else.

Supporter signs are the ones campaigns most often lose. They went in one at a time over six weeks, often by different volunteers, and there is no single list of where they are. Keep one, from the first sign onward.

The mistakes that cost campaigns money

Every cycle, the same handful of errors accounts for most of the signs municipal staff pull:

• Going up before the local window opens, even though the Region's 42-day window has
• Measuring the setback from the sidewalk instead of the curb
• Full-height signs inside the 20 m sight triangle at a corner — the exact spot with the best visibility
• Cable-tying to a stop sign, street name or utility pole because the ground is frozen or hard
• Signs at or beside a voting location, which get removed on voting day itself
• Working to the seven-day deadline when the placement sits on a regional road with a 48-hour one
• No record of supporter-lawn placements, so a dozen signs are still standing a week later

None of these are hard problems. They are all consequences of placing several hundred signs quickly, at dusk, with volunteers who were handed a stack and a map and told to go.

If you would rather not run this yourself

Placing and retrieving a campaign's worth of signs is a routing and record-keeping problem more than a manual labour one. We install real estate sign posts across Durham Region every day, which means we already know the curbs, the sight lines and the municipal boundaries, and we already log every placement with an address and a photo.

We place signs that were printed anywhere — most campaigns already have theirs — and we schedule the removal sweep before the first sign goes in the ground, because that deadline is the one with a bill attached.

Verify before you place

Every date and dollar figure above comes from a municipality's own 2026 candidate material or election sign by-law, checked in August 2026. By-laws get amended mid-cycle, fee schedules get updated, and one Durham city's removal deadline is genuinely unclear from public sources right now.

Your Clerk's candidate package is the authority for your municipality. Read the election sign section of it before the first sign goes up — it is a few pages, and it is the cheapest campaign insurance available.
