n. — Automotive
a building, usually above-ground and with several storeys, serving as a parking area for motor vehicles.
Type: 1. Origin — Parkade is probably of Canadian origin, linked to the Hudson Bay department stores, which first appeared in Western Canada (see the first 1958 quotation). Boberg (2010: 179), with data gathered from self-reports, considers it primarily a Prairie and BC term (from Ontario eastwards parking garage is more frequently reported than parkade). Parkade is also the majority term in PEI (Boberg 2010). Chart 2 substantiates this finding. The term is most common in Alberta (see Chart 2), confirming overall the Prairie dominance from Boberg (MB, SK, AB) and BC, which can be partly explained by the western Canadian connection to the HBC department stores, as the first six of which, the "original six", opened in Victoria, Vancouver, Edmonton, Calgary, Saskatoon and Winnipeg (see HBC reference), where the term is frequent to this day.
Apart from Canada (see Chart 1), the term has currency in South Africa, where it is most likely an independent development. Some US locations have adopted parkade (see the one shown in Image 2, from Spokane, Washington). From a North American perspective, the term is Canadian also by virtue of frequency (Type 5).
See COD-2, which labels the term "Cdn". See Gravol and day parole for other terms with a Canada/South-Africa parallel.
