The service sector in Canada is vast and multifaceted, employing some three quarters of Canadians and accounting for over two thirds of GDP. The largest employer is the retail sector, employing almost 12% of Canadians. The retail industry is mainly concentrated in a relatively small number of chain stores clustered together in shopping malls. In recent years the rise of big-box stores, and Future Shop, have led to fewer workers in this sector and a migration of retail jobs to the suburbs.The second largest portion of the service sector is the business services, employing only a slightly smaller percentage of the population. This includes the financial services, real estate, and communications industries. This portion of the economy has been rapidly growing in recent years. It is largely concentrated in the major urban centres, especially Toronto and Calgary (bangking business services).
The Canada education and health sectors are two of Canada's largest, but both are largely under the purview of the government. The health care industry has been rapidly growing, and is the third largest in Canada. Its rapid growth has led to problems for governments who must find money to fund it.
Canada has an important high tech industry, and also an entertainment industry creating content both for local and international consumption. Tourism is of ever increasing importance, with the vast majority of international visitors coming from the United States. Though the recent strength of the Canadian Dollar has hurt this sector, other nations such as China have increased tourism to Canada.
