My thoughts (sorry I missed this)and I could be off the line here and others may not agree,but here are my thoughts:
Since most of the test candidates are directly moving to decision made and Oath, IRCC is probably picking some random cases to check and verify travel details again. It is a random check and since you have completed residency requirements in a stretch, I dont believe there are any flags. My gut feeling of possible question would be around your tourist trip and what made you think of applying for PR (proud moment?). Perhaps that is it.
When you submit your document: make sure to put it with a cover letter explaining the tourist trip and what you did, where you stayed (no need to provide any supporting documents). In my opinion, your only supporting document will be :
1- entry and exit stamps for you and each applicant
2- bio page of that passport (if there is a new passport then attach biopage of that passport too)
3- flight ticket (check in details - perhaps your email would have it) and hotel stay (if you have, if not provide a name of hotel and address)
4- (you may want to do this - if I were you, I would do this): attach all pages of current,last passport to show that there are no other travels in and out of Canada. My reason for doing this : IRCC may want to check with CBSA and that can be time consuming, so better provide them information upfront. There is always a discretion invovled , but full disclosure helps.
That's all I can think of. Others may add.
All the very best.
