In this case entire family was not PR. it was economic migration and not family one.
Sadly IRCC is ineffective which seen many cases before. Treating brain cancer would cost over 120k+ over 5 years. We’ve seen cases where only current medication is counted and nothing else not even scans over 5 years, oncology appointments, radiologist reading scans, etc. There would be significantly more costs than thar but some are likely while some are guaranteed. Not to mention nobody can predict treatment past 6-12 months in most cancer patients. Meanwhile some longterm residents are waiting months to see an oncologists (sadly some dying while waiting), many months for an MRI, we’re paying to send some to the US for treatment, etc. There is zero extra capacity in the system.
