Which of the following does not contribute to Toronto’s healthy economy?

Because of its diversified industrial base, with adequate land and substantial opportunities for manufacturing and development, Tornoto boasts a healthy economy. A large local market and labor force is provided by nearly 4 million population of metropolitan Toronto and more than 5 million people who live less than two hours by car from the city.
    As the center of Canada’s financial and corporate community, Toronto is headquarters for its largest banks and for most of the foreign banks in the country as well. The head offices of half of Canada’s top 50 corporations are also located there. The Toronto Stock Exchange is one of the largest in North America. The Eaton Center and nearby Simpson’s department store form one of the continent’s largest retail facilities.
    The Toronto metropolitan area has by far the greatest concentration of manufacturing activity in Canada. There are also high-technology firms, port-related enterprises, arts and culture industries, and numberous business and consumer services.
    The film industry, which began flourishing in the 1980s, is one of the fastest growing parts of Toronto’s economy. Each year more than 50 full-length films for cinema and telvision are produced. Many are financed by Untied States companies, which may use the location to stand in for other American cities - for example, Chicago, New York, or Seattle. Television programs, commercials, and rock music videos are also produced.
