Immigration categories are shown for the three main groups of permanent residents—family class, economic immigrants, and refugees—as well as for “other” immigrants who do not qualify in any of these categories. On an exceptional basis, the Immigration and Refugee Protection Act gives Immigration, Refugees and Citizenship Canada (IRCC) the authority to grant permanent resident status to individuals who would not otherwise qualify in any category—for example, in cases where there are strong humanitarian and compassionate considerations. In reference to labour market characteristics, the economic immigrant category is further divided into two subgroups: principal applicants, and spouse and dependants.
