Canada's wealth comes from the exploitation of its rich natural resources and from the work of its citizens. Canadians are employed in a variety of jobs. All of these jobs can be grouped into one of three categories: extractive industries, manufacturing industries and service industries. Industries that take raw materials from the natural environment are called extractive or primary industries. Canada has a wealth of natural resources. The extractive industries that have been developed to exploit these natural resources make an important contribution to the wealth of our economy. Without these extractive industries and the money they bring from other countries, Canada's economy could not exist in its present form. Yet only a small percentage of Canada's labour force work in extractive industries. Extractive industries rely on laboursaving machines instead of human labour. Manufacturing industries process the products of extractive industries into finished products. Manufacturing industries transform raw materials into many different forms to be used by consumers or by other companies. This processing may be done in one or more stages. For example, iron ore is transformed into steel in factories. This is called primary manufacturing. The steel is then sent to companies for further processing into cars, mining equipment, machines, nails, and other products-such as bicycle frames. This is called secondary manufacturing. Manufacturing industries are located in many towns and cities across Canada. Companies try to build their factories in densely populated areas because they want to near the people who buy their products. If they locate near their customers, then they save money on shipping costs. Manufacturing industries provide more jobs to Canadians than do extractive industries. Yet the number of people employed in manufacturing is still small in comparison to the third category, services. As with extractive industries, manufacturing process use many machines that require relatively few workers. Service industries provide services needed by the extractive and manufacturing industries, and by society in general. Without these services, society could not operate. The majority of Canadian workers do not produce 'goods' in their jobs. Instead, they provide 'services' for others. The range of services is very great and includes such things as retailing, office work, education, health care, communications, government, transportation, and personal services. Service industries in one form or another are spread over the entire country. In every community there are stores, banks, schools, police forces, and dozens of other services. The majority of service industries are found in town and cities because services are provided for people and there are many more people in urban areas. Canada's economy depends upon the creation of jobs in all three types of industry. Introduction All 1.________can be divided into three categories: extractive industries, manufacturing industries and service industries. Extractive industries Extractive industries are also called primary industries, which are 2.________with the exploitation of raw materials from the natural environment. 3.________ industries Manufacturing industries 4.________raw materials into products, which can be used by people or companies. Manufacturing industries can be grouped into primary manufacturing and 5.________ manufacturing. Primary manufacturing 6.________ steel from iron ore for further processing. Secondary manufacturing will then use the steel to make products like cars, bikes, etc. for people to use. Service industries Service industries provide services the other two industries need. Without these services, our society cannot 7.________. Service industries provide jobs for shop assistants, office 8.________,  teachers, doctors, and many others. Service industries mainly provide services for 9.________. Closing Our society is 10.________on all three types of industry.
