I think you are justified in following up given that TR to PR was supposed to be a streamlined (faster) process. There is a big difference between Service Standard (the goal) and Current Processing Times (the actual performance). I believe the 26 month processing time you were quoted is generic for all PR applications, and is not specific to TR to PR. And, although there isn't a highly publicized Service Standard for TR to PR Pathway, they have been 'trying' to meet a Service Standard of 6 months (for 80% of the applicants). It is actually listed in the document at the link below which is a review of 2021. Here is a repeat of a reply I provided back in July:
Technically the agent is misinformed. The Standard of Service is 6 months (for 80% of applicants) for TR2PR, but they appear only to count the time from Linking or AOR.
The following information was posted by IRCC in Feb 2022 and seems to confirm a desired TR to PR Service Standard of 6 months. It fits with many recent timelines where TR to PR applications are being processed in under 6 months (at least from time of linking or receipt of AOR to the time of PR). Of course, Service Standards aim to have 80% of the applications completed within the standard time, there are always exceptions, and IRCC does not seem to be counting the many months that people's applications have already been sitting in the original application portal where we all applied in 2021. It appears the 'Service Standard' only starts ticking when the applications finally get loaded into the GCMS (which then allows account linking &/or AOR and initiates the start of actual processing).
