Final answer:
The two fastest growing immigrant groups in Canada are the Chinese and South Asians, making these communities significant in Canada's diverse population.
Step-by-step explanation:
The two fastest growing groups of immigrants in Canada are the Chinese and South Asians. According to the 2010 Canadian census, there are more than one million Chinese and over half a million South Asians living in Canada. While the current surge of immigrants to Canada includes people from many different areas of the world, these two groups are particularly notable for their rapid growth. Although there are significant populations from other parts of the world, the influx from Europe, for example, is relatively smaller compared to past periods of immigration.
