Cory Barry was charged after Justin Wendland was stabbed twice in the chest without provocation at a bus stop outside the Times Colonist newspaper building in 2010.
In convicting Barry, a Supreme Court judge found the defence failed to prove the man suffered from a mental disorder to the point where he should be found not criminally responsible.
The question of whether Barry was mentally capable of understanding the severity of his actions played a key part in the trial.
But the judge ruled Barry understood that death was a likely outcome when he forcefully stabbed Wendland twice in the chest.
Barry will be sentenced later. (CFAX)
