A TTC bus collided with a fire truck while the emergency vehicle was at the scene of an earlier crash on Avenue Road and Wilson Avenue on Tuesday evening.
Crews responded to a two-vehicle collision in the area around 6:30 p.m.
One of the drivers reportedly suffered leg injuries.
Toronto police say the intersection was closed to traffic and the TTC was notified.
While officers were on scene investigating, a bus collided with the fire truck.
No injuries were reported in the second collision but roads were closed for a short time for the investigation and cleanup.
The intersection has since reopened.
