C

Today, we have a world economy. Canadian businesses and workers must compete with businesses and workers in other countries.

Every year, more Canadian factories are closing or moving。 They cannot compete with factories in countries where wages(工资) are low. In the future, there will be fewer jobs for factory workers in Canada.

Many Canadian businesses are trying to spend less money. For example, they are hiring more part-time workers and more temporary(临时的) workers. They are employing fewer permanent(永久的)full-time workers. More services, fewer goods. Canada’s economy is changing. Businesses are making fewer goods(for example: shoes and radios). But Canadian businesses are providing more services to people.

In the future, there will be more jobs for people who provide services. For example: sales people, waiters and waitresses, home health care workers, bakers and cooks.

There will be fewer jobs for other kinds of workers(for example: farmers , miners , fishermen, forestry workers and factory workers).Many new jobs will be in small businesses with 20 or 30 employees. Technology machines are changing the way people work. Business are using many machines (for example: computers and robots).

Businesses will need fewer workers. And some jobs will disappear. Many grown-ups will have to go back to school or train for new jobs. Workers will not stay in the same job for their lifetime. The population of Canada is changing.

Today, many Canadians are in their 30s and 40s. They need goods and services. As they get older, they will need different goods and services.

Canadians come from many cultures. They have different customs and religions. Employers and workers must learn to work with many different people.
