Cleanup efforts are underway after a single-vehicle collision shut down a Highway 400 ramp in Woodbridge.

Ontario Provincial Police said the crash occurred around 4:15 p.m. Monday on northbound Highway 400 near the westbound Highway 407 ramp.

No injuries were reported in the collision. However, the ramp connecting Highway 400 northbound to Highway 407 westbound remains closed while crews clear the scene.

Police have not provided a timeline for when the ramp will reopen.
