A long-standing immigration policy apparently forces people with the surname Singh or Kaur—common Sikh names—to change their last names: Common Sikh names banned under Canada's immigration policy. If you apply to become a permanent resident, you'll recive a letter from the Canadian High Commission in New Delhi stating "the names Kaur and Singh do not qualify for the purpose of immigration to Canada." That's ridiculous.
