Retail There are three major shopping malls in the City of Victoria, including the Bay Centre, Hillside Shopping Centre, and Mayfair Shopping Centre. Mayfair, one of the first major shopping centres in Victoria, first opened as an outdoor strip mall on 16 October 1963 with 27 stores. It was built on the site of a former brickyard in the Maywood district, a then-semi-rural area in the northern part of Victoria. Woodward's was Mayfair's original department store anchor upon the mall's opening. Mayfair was enclosed and renovated into an indoor mall in 1974. The mall underwent three later expansions in 1984 (with the addition of Consumers Distributing), 1985 (expansion of the mall food court) and a major expansion in 1990 that saw the addition of more retail space. The Bay (now Hudson's Bay) replaced Woodward's as Mayfair's department store anchor in 1993 following Hudson's Bay Company's acquisition of the Woodward's chain. Mayfair now offers 117 stores and services including Hudson's Bay and Toys "R" Us. It has of retail space and it also provides customers with rooftop parking. Technology industry Advanced technology is Victoria's largest revenue-producing private industry with $3.15 billion in annual revenues generated by more than 880 tech companies that have over 15,000 direct employees. The annual economic impact of the sector is estimated at more than $4.03 billion per year. With three post-secondary institutions, eight federal research labs, and Canada's Pacific Navy Base, Victoria has many of the elements required for a strong technology sector, including Canada's highest household internet usage. Tourism Victoria is a major tourism destination with over 3.5 million overnight visitors per year who add more than a billion dollars to the local economy. As well, over 500,000 daytime visitors arrive via cruise ships which dock at Ogden Point near the city's Inner Harbour. Many whale watching tour companies operate from this harbour due to the whales often present near its coast. The city is also close to Canadian Forces Base Esquimalt, the Canadian Navy's primary Pacific Ocean naval base. Downtown Victoria also serves as Greater Victoria's regional downtown, where many night clubs, theatres, restaurants and pubs are clustered, and where many regional public events occur.
