Need advice on clearing a incorrect IRCC flag?

Hoping to get some help and clarity with this case.

My friend who currently lives in the Netherlands, wants to come visit me and tour Ontario for about a week or so. However as things stand right now they're not able to attain an approved eTA from immigration.

The reason for this is because they used to live in Canada for a bit from 2006-2008, we went to the same middle school, they were a minor child at the time, and in 08 their parents had received a removal/deportation order, therefore they moved back to the Netherlands and have been living there since then.

My friend did try visiting back in 2024 with their mother, because their grandfather who lived here at the time and was a Canadian citizen, was in the hospital. However their application got flagged, got linked to their parent's removal order back in 2008 and their ETA got rejected. They tried to appeal it but it didn't work and just received the same message they got the first time from the automated system. And unfortunately their grandfather passed away and they weren't able to see them one last time.

I think it's highly unfair that they were rejected because the IRCC's own policy states that they should be exempt and shouldn't have had their application flagged since they were a minor at the time they got the removal order with their parents in 2008. Some of the IRCC tier-1 agents suggested that they may need to apply for ARC, however this is what their OWN website states:

IRPA Provision: Paragraph A42(b) (Imcompanying Family Member Inadmissibility)

IRCC Operational Manual: ENF 11 (Verifying Departure) explicitly states: "Persons who have been issued any removal order on the basis that they are an accompanying family member under paragraph A42(b) do not require an ARC."

Official IRCC Public Guidance: Under the Authorization to Return to Canada overview on Canada.ca: "If you were removed from Canada because you were accompanying a family member who was removed from Canada, you don't need an ARC to enter Canada."

I have gotten a case worker from my MP's office involved who is acting as a liason and has taken some records and documents from my friend, and my friend has also given them an authorization form to make me a legal contact as well. However this was back in May of this year and there hasn't been any progress. The only thing we've heard is that the IRCC member is looking into the matter, but this was back in early July. And since then the case worker at the MP's office has said they have not heard anything from their IRCC contact.

I understand these types of things can take some time but the lack of communication and no outlook on ahead is kind of making us both pretty anxious and frustrated. Considering the case itself isn't anything complicated in regards to their own policies. And if there's any way or other avenue to possibly expedite this matter it would be a huge help.
