The multicultural approach attempts to create unity through difference, holding that although a nation's subcultures are diverse, those subcultures share common values. In terms of legal policy, Canada was one of the first nations with an official multicultural act and they are an officially bilingual nation, using both English and French. Cultural assimilation is a process of consistent integration whereby members of an ethno-cultural group are "absorbed" into an established, generally larger community. This presumes a loss of many characteristics of the absorbed group. The two approaches are quite different. The contrasts between them are often given comparative analysis in France (assimilation) and Britain (multiculturalism). The world continually refers back to these two case studies in order to weigh the pros and cons of these two social models. With both countries holding tight to these different models and with other countries diverging in their choice between them, the debate continues to be hotly contested and highly important to how societies deal with diversity in an attempt to construct the best, healthiest, safest, most dynamic, and most productive nation and world.
