If you’re stuck in traffic on Hwy. 400 Tuesday, the root of the problem is likely celery.

No injuries have been reported.

Drivers can expect the highway to be closed for several hours.The ramp from Hwy. 9 eastbound to the highway is also closed, OPP said.

Celery isn’t the only produce to take stalk on Ontario’s highways. This past July, thousands of apples spilled onto Hwy. 401 in west Toronto after a tractor struck a meridian in a westbound express lane just past Keele Street.
