The following excerpt is from Tomlinson v Canada (Public Safety and Emergency Preparedness), 2013 CanLII 100313 (CA IRB):

This responsibility, the respondent submits, rests on the applicant at the time of completing the application for permanent residence and is a continuing one. It was held in De Leon v.
