As the same as the other Commonwealth countries, Canada and Australia have a lot of similarities in the culture. The first is the advantage in language. English is the official language both in Canada and Australia and this can greatly lower the risk of communication difficulties in business, which will undoubtedly reduce the cost in language transformations. The second advantage is the immigrant background. Both countries are nations of immigrants, which make them easy to share the same immigrant value. Canada is a typical immigrant nation, which immigrants come from different regions of the world having different languages, customs, religious beliefs, historical and cultural background, economic environment and lifestyle and come together to create the multicultural society. On the basic of diversity, the different background of history and reality has forged Canada into a multicultural society--Mosaic Community (Watkins 1993). In Canada, multiculturalism is advocated by the Government as a matter of policy. However, despite multiculturalism has many advantages in social integration，the disadvantage is also very clear. In Canada, in addition to English and French as the official languages, many languages are spoken by residents in life. According to 2011 National Household Survey，the population reported speak English as their mother tongue is 57.8% while the French is 21.7%, and 20.6% of Canadians use the other language as a mother tongue except English or French, which is 6.8 million people in Canada. (Statistics Canada 2013). Religions in Canada also show the diversity, the largest faith in Canada was Christianity. About 22,102,700, or two-thirds of Canada's population (67.3%), reported that they were affiliated with a Christian religion. Muslim, Hindu, Sikh and Buddhist also have a huge population. Such diversity also appears in the immigration, place of birth, citizenship, ethnic origin, visible minorities and so on. So fully considering the Canadian multiculturalism is the obligatory course. Regionalism is a problem that been in existence since Europeans come to Canada. “Regionalism” is one of the preeminent facts of Canadian life (Simeon & Elkins 1974). The cleavages between English-Canadian and French-Canadian are everywhere in Canadian politics and economics. Each province has its own unique tradition, which will bring much difficulty in formulating a unified investment strategy.
