Oshawa sign permits explained: when you need one, how to avoid delays, and what the approval process actually looks like.

You've designed the perfect sign. You're ready to move forward. Then someone mentions permits.
Suddenly you're navigating City of Oshawa by-laws, trying to figure out if your sign needs approval, what forms to fill out, and how long the whole thing takes.
Here's the truth: most commercial signs in Oshawa require a permit. But the process doesn't have to be complicated.
Let's break down exactly when you need a sign permit in Oshawa, what the City looks for, and how to avoid the delays that trip up most business owners.
Not every sign needs City approval—but most do. Here's what typically requires an Oshawa sign permit:
Wall-Mounted Signs
Channel letters, lightbox signs, or any sign attached to your building's exterior wall. If it's visible from the street and attached to your building, you need a permit.
Freestanding Signs
Monument signs, pylon signs, and ground-mounted directional signs all require permits. These often need site plan approval in addition to a standard sign permit.
Projecting/Blade Signs
Signs that extend perpendicular from your building (common in downtown areas) need permits and must meet specific projection distance requirements.
Electronic Message Centers (EMCs)
Digital signs or LED message boards have additional regulations around brightness, animation, and placement.
Temporary Signs (In Some Cases)
Banners, A-frames, and promotional signage may need temporary permits depending on size, duration, and location.
What Doesn't Require a Permit?
When in doubt, check. The City of Oshawa's Planning Services can confirm whether your specific sign needs approval.

Most delays aren't about the sign itself—they're about incomplete applications or missing information. Here's what holds up approvals:
1. Missing Site Plans or Drawings
The City needs to see exactly where your sign will be located relative to property lines, parking areas, and other structures. A hand-drawn sketch won't cut it—you need scaled drawings.
2. Sign Size Exceeds By-Law Limits
Oshawa has specific size limits based on your property's frontage and zoning. If your proposed sign is too large, the application gets rejected and you start over.
3. Inadequate Setback Distances
Signs must be a certain distance from property lines, roadways, and sidewalks. Placing a sign too close to the street triggers a resubmission.
4. Lighting Issues
Illuminated signs have brightness limits and restrictions on flashing or moving elements. Overly bright signs or animated displays can violate by-laws.
5. Incomplete Applications
Missing signatures, unpaid fees, or incomplete forms automatically delay processing. The City won't review your application until everything is submitted correctly.
6. Zoning Conflicts
Some zones have stricter sign regulations than others. Commercial zones generally allow more flexibility than residential or mixed-use areas.
Here's what happens from application to approval:
Before submitting anything, confirm your sign complies with Oshawa's Sign By-Law. Key things to check:
The City of Oshawa's Planning Services can answer questions before you apply.
A complete application includes:
Missing any of these? The application doesn't move forward.
Applications can be submitted in person at Oshawa City Hall or online through the City's planning portal. Once submitted, the City assigns a file number and begins the review process.
The Planning Services department reviews your application against the Sign By-Law. They check:
If something doesn't comply, the City contacts you with required changes. You'll need to revise and resubmit.
Once everything checks out, the City issues your sign permit. This usually includes conditions like:
You can now proceed with fabrication and installation.
Typical Timeline: 2–4 weeks for straightforward applications. Complex projects (large freestanding signs, digital displays) can take 6–8 weeks.

After installation, some signs require a final inspection by the City to confirm everything was built according to approved plans. Schedule this promptly to avoid compliance issues.
Here are some common regulations business owners should know:
Sign Size Limits
Maximum sign area is usually calculated as a percentage of your building's street-facing wall or your property's frontage. Larger properties can have bigger signs.
Height Restrictions
Freestanding signs typically can't exceed 6–8 meters in height (varies by zone). Wall-mounted signs can't extend above the roofline.
Setback Requirements
Signs must be set back from property lines, usually 1–3 meters depending on sign type and location.
Illumination Standards
LED and internally lit signs must meet brightness limits (measured in nits or lumens). No flashing, moving, or animated elements except for approved electronic message centers.
Maintenance Requirements
Signs must be kept in good repair. Faded, damaged, or non-functional signs can result in orders to repair or remove.
