McMaster University's peak demand for parking is 2,803 vehicles, or 69% of capacity (est. 3963 total) according to their campus capacity study of April 2011. To create a required 30 metre naturalized buffer zone between the existing parking and Ancaster Creek, McMaster has committed to remove up to 480 parking spaces along the creek edge this spring (2013), which means the total supply drops to 3,483 spots.
