I don't know if Toronto's Automated Speed Enforcement cameras have a 'grace' margin, either baked in or by policy, but expecting an absolute accurate speed control by a driver is a bit unrealistic. Transport Canada - or the US DOT for that matter - do not have regulatory standards on speedometer accuracy. North American manufacturers use an SAE target as their benchmark:Except that the camera system can't issue demerit points. So, drivers are already getting a "discount" over being caught by an officer. The question is though, why should anyone be given a margin of grace? Everyone driving on the road (legally) has been tested on and issued a license based on their ability to follow the rules of the road. A single warning first maybe, by email, automated phone call and mail seems more than reasonable. But why reduce fines? If someone commits theft under $1000, I don't personally think they should be allowed to keep some of it for themselves. The maximum speed limit is also not simultaneously the minimum. Even by driving the exact maximum, people know that is the maximum.
"Manufacturers are guided by a standard set by the Society of Automotive Engineers known as J1226 Electric Speedometer Specification. At speeds above about 90 km/h the allowable range for speed is 4% of the highest reading shown on the speedometer."
As for issuing warnings, I don't know if the technical aspects of the ASEs allow them to be networked and store incident data. Even if they are or could be, the legislation would have to allow increased fines for subsequent convictions (note, 'convictions', not incidents, so it would have to be a previous infraction where the fine was paid). Actions such as phone calls and letters sounds like an administrative nightmare. As far as I know, the MTO does not record email address of vehicle owners.
