A striking York Region Transit worker was struck by a vehicle while walking a picket line in Richmond Hill on Thursday morning.

Ray Doyle, president of Amalgamated Transit Union Local 1587, said the worker wasn't seriously injured in the collision, which occurred in the bus loop at Richmond Hill Centre.

Doyle said the worker was hit by a car driven by a person who was trying to force his or her way through the picket line.

He said the car's driver remained at the scene.

York Regional Police officers were called to the scene, but it's not known if any charges will be laid.

Striking workers also picketed outside a Veolia garage on Keele Street, where a rally was held earlier this week.

At both picket lines, workers held up buses for a few minutes, causing delays during the morning commute.

More than 500 YRT and Viva bus drivers and mechanics have been on strike since Oct. 24, shutting down about 60 per cent of the region's bus routes.
