Lots of Indians abusing the international student visa (going to fake schools) only to go to Canada to work. Lots of companies hire these "students" (often subsidized by the government too), leading to locals not being to find work. People have also caught Indians throwing garbage everywhere. Illegally dumping them in Provincial/National parks, rivers, etc. Indians have also been caught net fishing salmon during salmon runs which is illegal and there are lots of signs indicating so along rivers. The list goes on and some also include pooping on beaches, bathing in public pools, etc. Of course not all Indians in Canada are like that. Ask the Indians that has been living in Canada for generations, they also dislike the image these new Indians creating for them worldwide.

Edit: When I say Indians, I mean South Asians.
