The East Gwillimbury GO Station was selected as a field site for evaluating cleaning practices on permeable pavement for the Evaluation of Permeable Pavements in Cold Climates.   The site was constructed in 2004 and consists of permeable interlocking concrete paver commuter drop off and pick up area as well as parking.

This 3 year study of the performance of different types of permeable pavements at the Living City Campus at Kortright in Vaughan is a research collaboration between STEP and the University of Guelph.  The different cleaning treatments ranged from hand sweeping, low and high suction vacuum, pressure wash, mechanical sweeper, regenerative air and vacuum-sweeper trucks.
