Shootings on Toronto Transit Commission vehicles or platforms, such as the one that occurred at Osgoode subway station Thursday, are rare, though not unheard of.

In one of the most brazen shootings in years, a group of young men opened fire inside a crowded subway car in between the St. George and Spadina subway stations on March 28, 2008.

A 17-year-old woman was shot in the leg in that incident. Remarkably, there were no other injuries.

In 2004, a 24-year-old man and an 11-year-old girl were wounded during a shooting on a TTC bus in the middle of a Sunday afternoon.

Police said in that incident, about 40 people were travelling on the bus in the city's north end when a group of young men began speaking to another man at the back of the bus. One member of the group pulled a gun and began shooting.

In 2005, a TTC driver lost sight in one eye after being shot in the face. The driver was caught up in a skirmish between two groups that erupted at a TTC bus stop in Scarborough.

Another shooting was reported in July 19, 2000, near Lawrence Avenue East and Markham Road. A man was shot on the bus at 3:30 in the afternoon.

Most recently, on Dec. 21, 2008, a TTC bus driving along Eglinton Avenue West near Dufferin Street was struck by two bullets fired by someone on the street.

Police said the bullets "narrowly missed" the passengers on the bus.
