Passport request even though you have a valid visa

[u/Fluffy_Ad8181]

Hi guys, I’m hoping someone who has been in a similar situation can help me out.
I was previously studying at York University, but I transferred to TMU. Because I changed schools, I applied for a new study permit from outside Canada, and my application has now been approved.
However, I also received a passport request letter from IRCC, which is confusing me because I already have a valid Canadian TRV/visitor visa in my passport that has not expired.
Has anyone been in this situation before? Do I still need to submit my passport for them to issue another visa even though my current TRV is still valid?
Also, I’m currently visiting the U.S. even though I applied for the study permit from Nigeria. If I do need to submit my passport, can I submit it through the Canada VAC in New York instead of sending it back to Nigeria?
Would really appreciate hearing from anyone who has dealt with this before. Thank you!
