You will be able to see some insight information.See a sample. Please note that the details in your file will depend on your individual circumstances and the stage of processing. Why it is important? Well in 2022 a story broke out of thousands and thousands immigration application were assigned to an inactive officer for processing, and those applications stuck in limbo. CBC did a story on it: https://www.cbc.ca/news/canada/ottawa/ircc-immigration-officer-container-placeholder-code-inactive-list-1.6669571Can you explain why GCMS is good idea ? How could affect the process and how to request it ?
Thanks
Having access to your GCMS notes at least equip you with some information and insight that might be useful and helpful down the way.
I have to agree with @yyzstudent it most likely will not help with your application in any way (will not speed it up)
