RIM Park is a 500-acre (2 km²) city park facility offering both outdoor and indoor amenities located at 2001 University Ave. East, which is on the northeast side of the city of Waterloo, Ontario, Canada, close to the Eastbridge neighbourhood. Key facilities and features include the Manulife Financial Sportsplex and Healthy Living Centre, the heritage Elam Martin farmstead, The Benchwarmer sports bar, and the Grey Silo Golf Course. The eastern edge of the park borders on the Grand River for 1.5 km, and the park grounds host about 7 km (4 miles) of asphalt trail loops.
In the planning stages, the multi-amenity park had been called Millennium Recreation Park, however the name RIM Park was chosen to acknowledge the large contributions from its primary donor, the employees of Research In Motion (RIM) (now doing business as BlackBerry Limited since January 2013), who contributed $2 million in 2001. The total up-front cost of building the park was $56.7-million, most of which was financed by a lease-style loan. Parts of the park opened in June 2001, and the grand opening was held on November 3, 2001.
