Immigration, Refugees and Citizenship Canada (IRCC) rank candidates in the pool using a points-based system called the Comprehensive Ranking System (CRS).They select the highest-ranking candidates from the pool and invite them to apply for permanent residence.
Each invitation round has a set of instructions that are:
- posted online at the time of the invitation round
- used by the Express Entry system to invite candidates from the pool
The instructions include:
- the date and time of the invitation round
- the number of candidates that will get an invitation to apply
- which immigration program(s) are included in the round (some invitation rounds may only invite candidates for 1 program, for example only from Federal Skilled Trades)
