Ontario Speeding Ticket Calculator: Fine and Demerits

Getting a traffic ticket in Ontario is a two-part shock: the fine on the paper, and everything the paper does not spell out. The dollar figure is only the start — every set fine carries a fixed court cost and a victim fine surcharge, and the conviction quietly adds demerit points to your driving record.

The calculator above does the full line-item math for the common offences, using the official set-fine schedule. This guide explains where each number comes from, which zones double the fine, and when a ticket stops being payable and becomes a court date.

How Ontario Speeding Fines Are Calculated

Ontario does not use flat fines for speeding. The Highway Traffic Act sets a per-kilometre rate that climbs in bands — the faster you were going over the limit, the more each kilometre costs you.

Kilometres over the limit	Set-fine rate	Demerit points
1 to 19	$3.00 per km/h	0 (up to 15 over)
20 to 29	$4.50 per km/h	3
30 to 49	$7.00 per km/h	4
50 or more	$9.75 per km/h — court summons, not payable	6

The band edges matter enormously. At 19 over, you pay $57 in set fines and get zero points. At 20 over, the rate jumps to $4.50 per kilometre and 3 demerit points land on your record. One kilometre per hour is the difference between a fine-only ticket and a conviction that follows you for two years.

The Line Items on Your Ticket

The set fine is only the first line. Every Ontario traffic ticket adds two mandatory extras:

• Court cost: $5.00. Fixed on every ticket, no exceptions.
• Victim fine surcharge. A sliding scale based on the fine: $10 on fines up to $50, $15 for $51 to $75, $25 for $101 to $150, $50 for $201 to $250, $125 for $501 to $1,000, and 25 percent of the fine above $1,000.

So a 30-over ticket is not just $210 (30 x $7.00). It is $210 plus $5 court cost plus a $50 surcharge: $265 all-in. The calculator above shows every line so the total never surprises you.

Zones That Double the Fine

Two kinds of zones double the set fine before the add-ons:

• Community safety zones — designated areas, usually around schools, where the doubled fines apply around the clock.
• Construction zones with workers present — the doubling applies when workers are actually on site.

Doubling applies to the set fine only; the $5 court cost stays the same and the surcharge is recalculated on the doubled amount. A 20-over ticket that would be $90 in set fines becomes $180 in a school zone — and the surcharge climbs with it.

When Speeding Becomes Stunt Driving

Stunt driving is not just very fast driving — it is a separate, much more serious charge with its own sanctions. The speed thresholds are:

• 50 km/h or more over the limit where the limit is 80 or higher
• 40 km/h or more over the limit where the limit is under 80
• 150 km/h or more anywhere, regardless of the limit

The punishment starts at the roadside, before any court date: an automatic 30-day licence suspension and a 14-day vehicle impound. On conviction, the court can impose a fine between $2,000 and $10,000, up to 6 months in jail, and a licence suspension of 1 to 3 years — plus 6 demerit points.

Because only a judge sets the final penalty, the calculator above deliberately shows no dollar total for stunt-level speeds. Any tool that invents one is guessing.

Red Lights, Stop Signs, and Camera Tickets

Not every ticket is about speed. The two most common intersection tickets carry published set fines:

• Running a red light: $325 set fine, 3 demerit points. Total with add-ons: about $405.
• Disobeying a stop sign: $110 set fine, 3 demerit points. Total with add-ons: about $140.

Camera tickets work differently. A red-light camera ticket goes to the vehicle’s owner and carries the fine but no demerit points — points require identifying the driver. Automated speed enforcement (speed camera) tickets work the same way: fine, no points.

Careless Driving: The Court Decides

Careless driving is the charge police reach for when the driving was dangerous but does not fit a specific box — aggressive weaving, a near-miss caused by inattention, or a collision where someone was clearly not driving with due care.

There is no set fine for careless driving. The court decides, within a range of $400 to $2,000, and can add licence suspension or jail time in serious cases. Every careless conviction also carries 6 demerit points — enough to put a G1 or G2 driver at the second-warning level in a single conviction.

What the Points Mean for Your Licence

The fine is paid once; the points linger for two years and can cost you the licence itself. Novice drivers (G1, G2, M1, M2) get a warning letter at 2 points, a second warning at 6, and a 60-day suspension at 9. Fully licensed drivers get letters at 6 and 9 points and a 30-day suspension at 15.

That is why the calculator shows the demerit result for your licence class alongside every estimate. A 3-point ticket is an annoyance for a full G driver and a warning letter for a G2 driver — same ticket, very different consequences. If you hold a motorcycle licence too, the same novice scale applies; the M1 practice test page covers the motorcycle-specific rules.
