It is very clear that they are not intentional in some cases. It may be made by a consultant or perhaps even by a family member. It can happen in situations that we can call humanitarian. Let me give you a concrete example.
A young Congolese woman was raped in that country when she was 14 years old. She did not declare her child. Her parents were accepted as refugees through family reunification. The young woman came, but she was ashamed to declare that she had had a child as the result of a rape. She was caught by that darned paragraph 117(9)d of the immigration and refugee protection regulations. She was helped to put in a sponsorship application on humanitarian grounds.
In certain cases, people do not declare family members. She could have been accused of making false statements. Luckily, she was not charged. If she had been charged and found guilty, not only would she not have been allowed to bring her little daughter with her, but she would also have been inadmissible to Canada for two years. Under Bill C-43, she would be inadmissible for five years. That example shows the extent to which the measures are much too extreme.
