1 mile = 1.609 kilometers, so 114 km/h = just under 71 mph. Speed limit here in Ontario is only 100 km/h = 62 mph, although some other provinces have raised it to 110 km/h = 68 mph. This was in a rural area where it’s easier for the cops to pick out a speeder. In the heavily travelled parts of the 400 series highways around Toronto speeds in excess of 130 or 140 km/h are quite common - there’s little room to pull people over, and there’s safety in numbers. It really makes no sense, because in good weather the lightly-travelled rural parts of the 401 would be perfectly safe at 150-160 km/h, while even 120 is too fast in the heavy traffic around Toronto.
Thanks for the explanation.
