It is the average processing times of "most" complete applications in the past 12 months.
"Most" means %80 of the applicants.
The remaining %20 of the cases are generally called "complex" cases and they are expected to take more than 27 months.
So yes, some lucky applicants who are in this group of %80, may get their MRs 3-4 months earlier.
But the AVERAGE processing time is still 27 months.
Besides, after AoR, it does not matter whether your application is online or paper.
Because all paper files were scanned and entered to IRCC system at the time when they issue AoR.
Also for Quebec cases,
- IRCC does not need to validate applicants educational certificates such as degrees, diplomas etc.
- IRCC does not need to check language proficiency and scores of particular language examinations.
and many other extra checks no need to be done.
While they also have to do these above checks for other residency streams they take shorter than Quebec.
Anyways, when I check the provincial processing times and compare it with Quebec, I see that there is still huge 6 months of difference.
