Implemented in January 2015, the Canadian Express Entry program is Canada's new system for managing immigration applications for several of the country's economic immigrant programs including Federal Skilled Worker, Canadian Experience Class, and Federal Skilled Trades. People interested in immigrating to Canada to live and work on a full-time basis, who meet the criteria for at least one of these immigration programs, can formally express their interest in becoming a permanent resident of Canada by creating an Express Entry profile. Once added to the Express Entry pool, candidates will be scored according to the program's point-based Comprehensive Ranking System (CRS), and this score will determine the candidate's rank within the pool. People with the highest scores will then be invited to apply to immigrate to Canada as permanent residents.
