If you are under a removal order, you might be served with a Pre-Removal Risk Assessment which is an application you may chose to complete should you have a fear of returning to your home country. You will need to demonstrate that you have a risk to your life and that your country of citizenship will not be able to protect you upon your return.
If your Pre-Removal Risk Assessment has been denied, Canada Border Services Agency will ask you to leave Canada within a few weeks. You will have 15 days from the date of the refusal to submit a judicial review at the Federal Court of Canada.
