A tractor-trailer flipped on its side at the intersection of Prince and Wales and Woodroffe around 2:20 a.m. this morning.
Ottawa Fire says the truck was leaking fuel, and had downed some power lines.
The truck driver was able to get out of the vehicle, and no injuries were reported.
A hydro pole was hit in the incident, and power was shut off to high tension wires.
A Hazmat team was called in due to the fuel leak. At this time, it's unclear how much fuel was spilled.
Crews are still on scene assessing.
