What are the proposed legislative changes?
The new rules would allow us to focus on getting the people we need.
Anyone will still be able to apply, but CIC would no longer be required to process all new applications. The new provisions would allow the Department to select among the new applications and choose those that best meet Canada’s labour market needs. Under the current system, which is much less flexible, CIC processes applications from skilled workers in the order in which they are received.
The Department will use this flexibility in an open and transparent manner. It will be based on instructions from the Minister, which will be published in the
Canada Gazette and reported in the Department’s annual report to Parliament.
The Department will maintain its commitment to the broad objectives of the
Immigration and Refugee Protection Act—supporting Canada’s economy and competitiveness, family reunification and protecting those in need. The legislative amendments are intended to respond to Canada’s labour market needs.
It will not apply to refugees and is not intended to affect our objectives related to family reunification.
