Durham Regional Police allege that the man was riding his bicycle on a sidewalk on Monday morning, before entering a crosswalk and striking a car that was making a turn in the Simcoe Street and John Street area.
Police say the cyclist was treated for minor injuries. He was not wearing a helmet.
The 52-year-old man has been charged with two offences under the Highway Traffic Act, including riding his bike in a crosswalk and driving the wrong way on a one-way street.
In a telephone interview, Sgt. Bill Calder told CBC News that he did not have statistics immediately available on how often cyclists are charged in Durham Region.
"We know even as kids we have to walk our bikes in a crosswalk," Calder said.
