Don't give up. You may not get the first job you apply for. Keep looking.

Ask the employer why he/she did not choose you.

Talk to your friends and family.
Keep in touch with people you know are working.

Take a part-time job while you look for other work.

Get into a job training program
(contact Canada Employment Centres).

Do volunteer work - you may make helpful contacts. This may lead to paid work.

Work for yourself.
For example, are you good at sewing?
Cooking? Cleaning?

Think about moving to another city or town.
There may be work there.

Review your skills - (See: Know Your Skills). You may have work skills in areas you never thought of.
