A worker died in hospital after being electrocuted in Vaughan Tuesday morning.

The victim was rushed to hospital with critical injuries after an industrial accident that happened around 9:30 a.m. on Highway 7, near Dufferin Street.

York Regional Police say the man was working along the highway when the boom of his vehicle struck the overhead hydro lines.

"As a result the truck was electrocuted as well as the worker and a portion of the truck actually did catch on fire," said Const. Andy Pattenden.

One westbound lane of Highway 7 remains closed between Dufferin Street and Langstaff Road for the investigation, the rest of highway has reopened.
