These notes should first be requested from the IRCC as they are the main department dealing with Immigration related applications, such as Permanent Residency. The CBSA and CSIS are other government organizations, which the IRCC can engage, as required, for a particular case. Usually, CBSA and CSIS are engaged for detailed Security Screening. However, the CBSA and the CSIS are not directly involved in the immigration process.
Which department did you request your notes from? Keep in mind that notes from the IRCC can be delivered through email if that option was selected while ordering the notes. However, if the notes were ordered from CBSA and CSIS, then they usually come in the postal mail, even if a request for online delivery was made. As I mentioned above, notes should be requested from the IRCC first. After they arrive, and based on what you find in them, only then go for notes from CSIS and CBSA (which may not be detailed as well).
