the way i look at it is it can go one of two ways at this point:
1. IRCC reaches out to you asking if you can land before a certain date when your medicals are expiring.
2. IRCC extends our medicals validity date and/or requests you to retake the medicals.
the first i'm assuming will only happen if your BG check has cleared and you're in the green. the second will happen if your BG check results still haven't come in fully. keep in mind, this is no just the RCMP results we are talking about here; this is all agencies: FBI, Interpol, local agencies etc. i honestly feel a lot of these delays end up being due to th processing times taken by local law enforcement agencies, since that is not in IRCC's control.
either way, at this point it is highly unlikely to be rejected based on eligibility at least. let's hope this week continues to see some movement in the backlog in the Ottawa office
