Read https://www.canada.ca/content/dam/ircc/migration/ircc/english/resources/manuals/enf/enf04-eng.pdf Section 11.4I also spoke to an immigration lawyer in BC, and she said same thing as CBSA. Funny they would both say the same thing. She also said I had mitigating reason to be away longer anyway. She said even if CBSA asked me questions they would still allow me in, as have proof as to why I was in UK. Prosecuting a parent for historical abuse is reason for compassionate grounds. Nobody can be at fault for having no control as to how long a crime takes to be investigated. However, she said I would be able to get back in anyway. She has been immigration lawyer for 21 years.
In cases where: permanent resident status is established; and the BSO believes on a balance of probabilities or reasonable ground to believe, as the case may be, that the person is in non-compliance with IRPA for failure to comply with residency obligation (A28, A41(b)), or inadmissible to Canada for any other reasons outlined at A34, A35, A36, A37, A40, or A41;
the BSO at Immigration Secondary may report the person (pursuant to A44(1)) if there is sufficient evidence to support an inadmissibility allegation. In the absence of sufficient evidence to support the writing of an inadmissibility report, the BSO may enter any available information into GCMS (date of entry, last country of embarkation, current address in Canada, etc.) and forward notification of the same to a CBSA inland office in Canada to determine whether an investigation is warranted.
