GrandRiver and Hamilton CarShare's nonprofit co-op grants drivers a self-serve, environmentally conscious, and space-saving alternative to automotive ownership through occasional car rental on a pay-per-use basis. After their applications, Simple Plan members pay an additional hourly rate for actual drive time ($9), monthly insurance fees ($9), and refundable deposits. Located in central, easy-access lots in Waterloo, Kitchener, and Hamilton, drivers harness one of CarShare's 16 vehicles, for which gas, regular maintenance, and occasional time travel is included in the hourly rate. Drivers may reserve the closest car to their current location or choose their favourite four-wheeled steed, such as a Toyota Yaris or Mazda 5 via phone, Internet, or telepathy. GrandRiver and Hamilton CarShare plans to begin offering cargo vans and pickup trucks in the fall. Rental slots run as short as 30 minutes and as long as is necessary. Through promoting occasional car use, GrandRiver and Hamilton CarShare aims to encourage greater use of green transit modes such as public transit, cycling, and giant piggybacking.
