More than 4,000 crimes have taken place on TTC buses since 2010, with fraud the most prevalent criminal offence.
According to a report by The Toronto Star, fraud, particularly relating to bogus Metropasses accounted for 952 of the 4,000 crimes, with assault on bus drivers a close second with 896 incidents reported.
Assault on bus passengers was third, with mischief and threats rounding out the top 5.
The report by the paper also identified the routes where most offences took place.
The 36 Finch West route, which runs on Finch Avenue between Finch subway station and Humberwood Boulevard was the most dangerous route with 322 incidents, mostly related to fraud.
The 35 Jane route was next with 260 incidents also mostly fraud related, with the 32 Eglington West route up third, registering 164 incidents with assault on an operator the top criminal offence on this route.
The Lawrence East Night bus also got a special mention as when ridership numbers were factored in, this route was associated with the most incidents per passenger.
However, despite these figures, the overall crime rate on Toronto buses has steadily declined over the past three years.
