RideFairTO, a group that advocates for stricter regulation of Uber and other ride-hailing services and which shared the emails with the Star, says the company’s impatience over the delays shows how its business model relies on a steady stream of low-paid drivers who quickly cycle out of the industry. The group says that since Uber arrived in Toronto that business model has led the company to resist any regulations that would hinder its ability to sign up workers fast.
