Merivale Road is an arterial road in the western part of Ottawa, Ontario, Canada. It starts at Island Park Drive just north of Highway 417 and continues south until it ends at Prince of Wales Drive in Rideau Glen. South of Clyde Avenue, Merivale is known as Ottawa Road #17, while north of Clyde it is Ottawa Road #63.
From Island Park Drive to Carling Avenue the road is as a small collector route, passing the Westgate Shopping Centre. South of Carling Avenue it is a minor arterial road that goes through the Carlington residential neighborhood. It passes just west of the Central Experimental Farm, land owned by the federal Government of Canada.
South of Baseline Road, Merivale Road turns (it is actually the continuation of Clyde Avenue and Maitland Avenue) and becomes a major arterial route through a commercial district that contains several major malls, dozens of restaurants and radio and former CTV broadcast facilities (CJOH-TV, building structure was badly damaged by fire in 2010 and the building was demolished in 2011). During the 1950s through the 1990s prior to the City of Nepean's amalgamation with the city of Ottawa, this area of Merivale Road formed the largest commercial shopping district within the city of Nepean and a major shopping area for the National Capital region. During the 1950s and 1960s several major box stores, such as Towers, Miracle Mart, Pascals, and Kmart, were located along Merivale Road along with major Canadian grocery chains such as Steinberg's and Dominion. The late 1970s saw the building of Merivale Mall at the intersection of Merivale and Viewmount Drive on the site of a former farm house and farm lands. It contained the box store Woolco as one of its major anchor stores. The building of the Meadowlands Mall at the intersection of Merivale Road and Meadowlands Road took place around this time, but it contained no large box stores.
