6. Will there be a cap on the number of candidates admitted to the Express Entry pool?
There is no limit to the number of people who may enter the Express Entry pool. We expect this to result in a range of candidates with a greater variety of skills and experience from which employers, provinces and territories can select to meet their needs. However, we will base the number of candidates who get an ITA for permanent residence on the Annual Immigration Levels Plan. The Levels Plan will still set out the broad admission ranges for the immigration programs that are part of Express Entry.
Express Entry will create an inventory of high-quality candidates who employers in Canada will be able to consider when they cannot find Canadians or permanent residents to fill job vacancies.
Under Express Entry, labour market demand, in the form of a job offer supported by a Labour Market Impact Assessment (LMIA) or a nomination by a province or territory will provide candidates with enough additional points and be ranked high enough to be invited to apply at the next eligible draw of candidates. Draws will be made from the Express Entry pool on a regular basis, and instructions for each draw will be posted on our website. Note that all job offers will be subject to Employment and Social Development Canada’s (ESDC’s) LMIA requirements in place at that time.
Employers and potential candidates will also benefit from faster processing. CIC’s goal is a six-month or less processing time from the day we receive a complete application for permanent residence to the day a final decision is made.
