Express Entry was first introduced in 2015 and replaced the former first-come,first-serve category system. It is the simplest and fastest way to immigrate to Canada as a skilled worker. It uses a comprehensive ranking system ( CRS ) to allocate points and evaluate applications. The points are based on various factors such as age, education, language, work experience and adaptability. The online profile remains active for up to 12 months in the pool of candidates after applying. The minister announces regular rounds of invitations based on the cut-off draws.
