Yes. There may be some variations, but most are processed in this order.
This is very logical too.
The first stage R10 (completeness check), if the application is incomplete, it will be rejected. This is why it is the first stage. Along with the R10, based on your PCC, the criminality is done, unless you are an inland applicant who need to submit the RCMP, which is requested later.
Around this time, the medicals is also done. Usually the eligibility will not start unless medicals are done, because if an applicant or a family member is medically inadmissible, there is no need to do the eligibility.
Then starts the eligibility, which is the comprehensive review of all your documents. It takes place in 2 stages and is time consuming, eating the most of the processing time.
Only after the eligibility is passed, the security will start. Since the security is done by agencies other than IRCC, like CBSA, CSIS and Public Safety, this is the last stage.
If your AoR is February 1, your R10 should be complete, and criminality passed by now.
But, since you have requested the notes, you should get a clear picture.
