Const. Brian Montague said the men were involved in a confrontation Friday evening and Reynolds was hit as the man tried to escape from an underground hotel parking lot.
"There was no substantial injuries at all," Montague said Monday.
He said officers have spoken with Reynolds, who had a sore knee and back but was OK to return to work the next day.
Montague said police spoke with several people, pulled security video and identified a suspect "quite early."
He said a man from Richmond, B.C., was arrested at the police station and remains in custody. His car has been seized.
Montague noted a charge of intimidation is uncommon and applies to someone who persistently follows someone or watches where a person works or lives.
Investigators considered Criminal Code and Motor Vehicle Act charges including assault, assault with a weapon, criminal harassment, hit and run and failing to stay at the scene of a crime but intimidation seemed most appropriate, he said.
Vancouver-born Reynolds is in the city to film his new movie "Deadpool."
