@AKKH thanks very much, this is an amazing thread. I did some research, although each consulate may have their own process, but with the excellent crowd-sourcing threads in the Canada forum
1. Montreal F2A tracker: https://docs.google.com/spreadsheets/d/1phSTiwuIBzBBDGDSwBTgA6iwPt6vhWgd_JQWlHoj7vE/edit#gid=0
2. Montreal IR1 tracker: https://docs.google.com/spreadsheets/d/1LvnDvX95_tfWtTvsJJM49PDPPvPKal0WG2rgdZHhsz0/edit#gid=1797779787
Average wait time from DQ to IL for F2A is well above one year, while that wait time for IR1 cases are almost non-existent: it's just one month.
In case anyone in the future comes across this thread, IMO it is a no-brainer to do the F2A to IR1 upgrade, plus that is also legally the most accurate state of your case anyways after citizenship.
