Enforcement fixes the problem:
The province’s ban on speed cameras has “significantly” affected speeding and driver behaviour at former automated speed enforcement sites, according to City of Ottawa data that shows compliance with posted speed limits dropped from 87 per cent to 41 per cent in the first three months after the cameras were removed.
High-end speeding, where drivers are at or exceeding 15 km/h above the posted speed limit, has also increased from 0.3 per cent to 4.5 per cent since the cameras were deactivated in November.
...
Instances of high-end speeding dropped from 14 per cent prior to the cameras being installed to 0.3 per cent after four years.
That rate rose to 2.2 per cent within a week of the cameras being removed in November 2025. The rate rose to 3.3 per cent after three weeks, 3.9 per cent after eight weeks and 4.5 per cent after 12 weeks.
