The four immigrant categories in Canada are refugees, family class, economic immigrants, other. The immigration and refugee protection act establishes categories that decide whether someone from another country can come to Canada and make permanent residency there and it lays out the objectives for these categories. The objectives of the immigrant and refugee protection act are Pursue social, cultural and economic benefits for all Canadians, respect the bilingual and multicultural character of Canada. More are support the development of minority official language communities in Canada, share the benefits of immigration and support a prosperous economy across all regions of Canada, reunite families in Canada and promote the successful integration of immigrants into Canadian society, recognizing that integration involves mutual obligations for new immigrants and Canadian society. Canada's point system only applies to economic immigrants not refugees and family-class immigrants if a person is not a refugee or a family class immigrant they must qualify under Canada's point system also economic immigrants make up the biggest group of immigrants to Canada. The six categories for Canada's point system are English and/or french skills, education, experience, age, arranged employment in Canada and adaptability. Health and safety help factor in accepting immigrants by seeing their health because their health could put Canadian health at risk, they have a condition that could endanger public safety or their health could put an excessive demand on Canada's health services. Canada's policy towards refugees is that in 1976 Canada made refugees one of its immigration categories. The change meant that Canada accepted refugees steadily, instead of crisis by crisis. Objectives of refugee immigration are to save lives and offer protection to people who are displaced and persecuted, fulfill and affirm Canada's international commitments to protect refugees. Two more objectives are to grant fair and consideration to people who claim to have been persecuted, as an expression of Canada's humanitarian needs and offer refuge to people facing persecution because of race, religion, political opinion or membership in a social group, and to people who face torture, or cruel and unusual treatment or punishment.
