The entrance to McMaster University is just east of the McMaster University Medical Centre; from Main St. W. westbound, turn right at this entrance then turn left almost immediately and proceed onto campus. Turn left at "College Crescent" and follow for about 150M to the parking gates on your left - directly across from the Arthur Bourns Building (ABB). The cost to park is $5 per hour up to a maximum of $20 per day. You must pay the parking ticket prior to leaving the lot at the kiosk located near the parking gates.
If you are only here for an hour, you can park on the street directly in front of ABB - you must pay for the parking ticket at booths along the street and leave the ticket on the dash of your car.
