How the Speeding Fine Calculator Works

Who this calculator is for

Use the interactive Speeding Fine Calculator when you know your recorded speed over the limit and want a general sense of where it lands on Ontario's fine scale. For the full explanation of how speeding offences work — including when speeding becomes a stunt-driving matter — see our Speeding in Ontario guide.

How it works

The calculator takes the speed-over-limit figure you enter and maps it to the same general fine and demerit-point bands shown in the table below. Ontario does not publish a single dollar-per-km/h formula, but the bracket structure is consistent: the further over the posted limit, the more serious the offence is treated, in both points and fine amount.

Why the exact number varies

Two tickets for the same speed over the limit can carry different fines depending on factors the calculator can only partly account for. Community safety zones — areas such as school zones or construction zones where Ontario allows increased penalties — can raise the fine for the same recorded speed. Whether the ticket was issued by an officer or by an automated speed camera also matters: camera tickets go to the vehicle’s registered owner and carry a fine only, with no demerit points, while an officer-issued ticket to an identified driver carries both. And set fines themselves are adjusted from time to time, so a figure from a few years ago may no longer be current.

What this tool can't tell you

It can't confirm whether your specific location was a community safety zone, whether your ticket was officer- or camera-issued, or the exact current fine schedule if it has recently changed. The most reliable number for your situation is always the amount printed on your actual ticket or court documents. Use this page, and the live calculator, to understand the general shape of how speeding penalties escalate — not as a substitute for the figure Ontario has already given you in writing.
