New TRV for an infant residing in Canada

[Elchinec]

Hi,

• I am a PR living in Canada
• My wife and child are here with me on TRVs. PR sponsorship app has been recently submitted
• Kid's passport expires in May, 2019 together with his TRV.
• We got him a new passport and are looking to apply for a new TRV.

Question: Is this possible? has anyone had a similar situation?
I might be doing a paper based TRV for him with an explanation letter and send it to Ottawa.

Any feedback from similar experience?
