Quite logical.Personally I think (although only a guess) that this is the case, too - we're now about 3.5 years post-covid border restrictions being lifted, a lot of people delayed their arrival/return to Canada until after that. So yep, 3 yrs + is when people have accumulated the physical presence days. Numbers applying for c'ship probably will start to decline gradually some time in 2026.
And even if IRCC were to 'staff up' for this, it would take some time from when they started seeing numbers rise.
