From @sjamieit.bsky.social:
The City of Ottawa posted the raw speed data from before and after Doug Ford banned speed cameras and the effect is so obvious it's not even necessary put a line marking when that happened.
This chart shows the percentage of drivers going 15km/h or more over the posted limit.
The data: https://open.ottawa.ca/datasets/52f34797978c44c1820b8b2d7a4ae3ed
