Foreign nationals who are inadmissible or who do not meet the requirements for Permanent Residence may make a written request for consideration under Humanitarian & Compassionate Grounds under subsection 25(1) of the Immigration and Refugee Protection Act. There are some restrictions with respect to examination of applications for H&C consideration.
Individuals who are without status and have been living in Canada for at least 3 years, can potentially get permanent residence on H&C Grounds depending on their circumstances.
