The CCFTA allows Chileans to work in Canada without a Labour Market Impact Assessment (LMIA). The process of applying for an LMIA is usually expensive, the cost of which is incurred by the employer, which means not all employers would want to go through this to hire you. It also takes time. For you, though, as a Chilean employee, you are exempt from this step, and you can start work immediately after arriving in Canada with a valid work visa.
