@SVChucko For Ottawa, I think the cure has been less-bad than the disease, but that will obviously vary from city to city depending on how well the taxi service was run before.

When I've talked to Uber drivers who used to drive taxis, they've told me that they earn about the same, but the big improvement is being able to choose when they drive rather than having it dictated by the plate owners (who often forced them to drive inconvenient or low-paying shifts).
