Toronto now has open boarding (i.e. you can enter at any door) through all its streetcar lines and many bus lines. The new streetcars have totally separated the drivers from the passengers, so payment is more of an honour system + fare cops* proposition, compared to the old "show the pass/pay the driver" paradigm. Boarding speed and fare evasion have both increased.

*: "Revenue Protection Officers", a totally non-Orwellian job title.
