Ontario is in the middle of the largest speed limit increase in its history. Between late June and the end of September 2026, roughly 938 additional kilometres of provincial highway move from 100 km/h to 110 km/h — and two of the biggest phases land this month, on August 21 and August 31.
Once it is finished, about 89 per cent of the provincial highway network will be posted at 110 km/h, up from 43 per cent.
The reaction we hear most often is some version of "so the police have backed off ten kilometres." That is not what happened. Almost nothing about how speeding is charged, priced, or punished has changed. One threshold has actually moved against drivers, and it is the most serious one on the books.
Which highways are changing, and when?
The increase is being phased in by corridor, not switched on province-wide:
- Late June — sections of Highways 401 and 416 in eastern Ontario
- July 31 — Highway 402 near London
- August 21 and August 31 — a larger group, including sections of Highways 7, 115, 400, 401, 416 and 417
- September 30 — the QEW, plus Highways 403, 404, 406, 407, 412 and 418
New highways still in development, including Highway 413 and the Bradford Bypass, are being designed for 110 km/h from the outset.
The number on the sign is the limit — not the number on the highway. This is the part worth carrying with you through the next two months. "The 401 is 110 now" is false in both directions: some sections changed in June, some change in late August, and some are not on the list at all. If you are driving 120 on the assumption that the whole corridor moved, you are speeding on any section that hasn't.
Default limits where nothing is posted are untouched: 50 km/h in cities and towns, 80 km/h elsewhere.
How is a speeding fine calculated in Ontario?
This is the mechanism that makes the rest of this article make sense. An Ontario speeding charge under s.128 of the Highway Traffic Act is priced on how far over the posted limit you were — not on your absolute speed.
The standard set fine brackets:
| km/h over the limit | Set fine rate | Demerit points |
|---|---|---|
| 1–19 | $3.00 per km | 0 |
| 20–29 | $4.50 per km | 3 |
| 30–49 | $7.00 per km | 4 |
| 50 or more | No set fine — court appearance required | 6 |
Add the victim fine surcharge and court costs on top. Fines double in a community safety zone and in a construction zone where workers are present.
Because everything is measured from the posted limit, raising the limit by 10 km/h genuinely does reduce the penalty for the same road speed. At 130 km/h you are 20 km/h over in a 110 zone — three demerit points, at the $4.50 rate. That same 130 km/h in a 100 zone was 30 over: four points, at the $7.00 rate, and a meaningfully larger fine.
So on the ordinary speeding side, the change is real and it favours drivers.
The one threshold that did not move
Now the part almost nobody has been told.
Stunt driving under s.172 of the Highway Traffic Act is defined by regulation — O. Reg. 455/07 — and it has three speed triggers:
- 40 km/h or more over the limit, where the limit is under 80 km/h
- 50 km/h or more over the limit, where the limit is 80 km/h or more
- 150 km/h or more, regardless of the posted limit
Look at what that does on a 110 km/h highway. The "50 over" trigger would put stunt driving at 160. But the absolute trigger is still 150, and it applies first. 150 km/h remains stunt driving on a 110 km/h highway — which is 40 km/h over, not 50.
On a 100 km/h highway the two rules coincided perfectly: 50 over and 150 km/h were the same number. Raising the limit lifted the floor and left the ceiling exactly where it was. The cushion between legal and catastrophic is now 10 km/h narrower than it was in June.
And stunt driving is not a bigger speeding ticket. It is a different order of problem entirely: a 30-day roadside licence suspension and a 14-day vehicle impoundment the moment you are charged — before any finding of guilt — then fines from $2,000 to $10,000, six demerit points, a possible jail term, a licence suspension on conviction, and the worst insurance consequence in the Highway Traffic Act.
Which means the driver most exposed by this change is the one who reads "the limit went up" as "there is more room now," and drifts from 130 to 150 on a road where 150 costs him his car at the roadside.
Will police enforce a 110 zone differently?
Nothing in the change alters enforcement powers, equipment, or discretion. Radar and LIDAR are used the same way, officers exercise the same judgment about what to charge, and the Ministry has been explicit that the higher posted limits do not signal tolerance above them.
If anything, expect more attention on the corridors that changed. New limits draw enforcement and media interest, and 400-series speed enforcement has already been a visible provincial priority through 2026.
What if the limit changed around the date of my ticket?
This is the practical litigation point in a phased rollout, and it is worth a call rather than a guess.
A speeding charge alleges a specific speed against a specific limit at a specific place and time. During a staged change, three records have to agree: the limit in force on that section on that date, the signage actually posted when you drove past it, and what the officer recorded. Regulations change on a fixed date; sign crews work through a list.
Nobody should assume a discrepancy exists. But this is precisely the kind of detail that gets examined in disclosure, and for the next two months the chance of the paperwork and the roadside disagreeing is higher than usual. If you were stopped in late June, on or after July 31, or in the days around August 21 and August 31 on any of the corridors above, the date on your ticket is worth checking against the date the section changed.
What this means for you, plainly
- Read the signs, not the headlines. Through September, the same highway can carry different limits on different sections.
- Your fine still comes off the posted limit. The higher limit lowers the penalty for the same road speed — that part is a genuine break.
- 150 km/h is still 150 km/h. The stunt driving trigger did not move an inch, and you now reach it 10 km/h sooner relative to the limit.
- Don't pay a ticket to make it go away. Paying is a guilty plea — here's what that actually costs you on your record and your premiums.
