Obviously being a Québec resident is a delay itself because the province of Québec has complete control over who it approves as a sponsorHonestly I don't think it depends only on if you have an straight forward file or a complex one or a red flag, but also if the agent who's working on your file is a fast one or not, if the office is fast or not (apparently Montréal really slow, Vancouver rather busy and Winipeg super fast..)..
I'm Sept 24 applicant, still no news, not even a ghost update and I do not see any red flag in my file. I've lived the last 5 years with my common partner at the same adresse abroad, I was never out of status (visitor while application send, now OWP), I'm even working now. I'm from a non problematic country as well. My partner has a very good paid job, but that dosen't matter for Quebec applicants. My partner is canadian. We have no kids or dependant, no criminal records. I only lived in my home country, few travelling and mostly here to visit my partners family. I speak English and French fluent. The only thing that could slow down is that we are living in Québec, but I saw now some Québec applicants getting updates... So I really don't see where there could be a red flag that causes that my application isn't getting any updates... I have probably just a slow agent or a new one that needs more time or I'm in one of the slower proccessing centers who knows... I don't worry cause there are 6 more months to go before we hit the 12 month mark.. so relax
The ones who got already a letter from CIC (AIP, SA, DM or Landing) which one is your processing office (apparently it should be stated at the bottom of the page)?
All Québec residents are expecting delays you are not the only one
anything can be the reason of delay even where you live causes delays and everyone knows that
