The attack happened about 6:45 p.m. Friday. Witnesses told police one man suddenly stabbed another.

Police say the suspect stabbed the victim and then boarded a train in an attempt to leave the scene, but the train was held and the suspect was arrested.

The victim suffered life-threatening injuries and was taken to hospital, where he later died.

"The two gentlemen are unknown to each other and we believe it was random in nature," said Insp. Don Coleman.

Gagnon is scheduled to appear in court on June 23.
