In February 2018 a petition was presented to the parliament
https://petitions.ourcommons.ca/en/Petition/Details?Petition=e-1263, which has to do with files that get sent to the CBSA and get stuck for indefinite amount of time. IRCC claims to have "no control" when files go to partner agencies - so basically there is no accountability.
I have been looking at cases that have had judgements when a Writ of Mandamus has been filed (Mandamus, or a ‘Writ of Mandamus’ means “we command” in Latin. Simply put, it is a command issued by a superior court to compel a lower court or an administrative body (a government officer/ ministry, agency, or corporation) to do or refrain from doing a specific act which that body is obligated to do under law or refrain from doing. Mandamus is used as a remedy by applicants to compel IRCC to do a specific act. One of the most common cases where mandamus is used is to compel IRCC to make a decision on an application where there has been an unreasonable processing delay.) Most cases seeking mandamus for the processing delays of a permanent residency application pertain to delays due to security screening. The problem with that is because it has to do with security, most people lose in court because the judge can't force IRCC to make a decision when security hasn't been cleared
I totally understand the importance of a security screening and have no problem with that. What I do have a problem with is the length of time it takes - again, no accountability, and files sit with the IRCC for years. As per the petition that was put before the government, there should be time limit to conduct security screenings. Unfortunately this is not the case.
