Canada's multiculturalism

Canada was founded on the basis of balance and dialogue among three very different peoples – Native, English and French. Canada’s current multiculturalism policy is a natural outgrowth of this founding – diverse peoples maintaining a strong sense of cultural identity within a framework that is supportive of all and encouraging of dialogue as the means to make decisions and maintain national unity. Based on Moghaddam’s description of the psychological phenomena relevant to functioning in a multicultural environment, would you say that he is optimistic or pessimistic about the long-term social benefits of Canada’s multiculturalism policy? Why?
