Answer:
The main difference between the American melting pot and the Canadian mosaic lies in the reception of the cultural differences of the immigrants in each country.
Thus, the United States historically sought to integrate immigrants to the predominantly Anglo-Saxon American culture, incorporating specific issues of each culture. Thus, for example, Italian elements such as pizza or pasta, German elements such as beer, or Latin elements such as Caribbean music were incorporated. But always within the framework of a single integrative culture, which discarded other less interesting issues for the cultural mainstream.
On the other hand, in Canada it was sought to adopt all foreign cultures, promoting the permanence of cultural values different from those of the Canadian mainstream. Thus, each nation maintained and continues to maintain certain cultural values that are celebrated alongside traditional Canadian values.
