Just to finalize the whole story, just received a copy of GCMS file (actually by email from the ATIP office). It seems that it was actually really good that we've sent a TRV app. In there I provided fresh tax returns, updated info and addressed some concerns on the prev TRV app. Looking through the notes, the officer had concerns that there is not enough evidence of our relationship and my intent to return to Canada. However further there is a correction, that now that he/she has seen the latest TRV app, she/he is satisfied that all is good and imm visa issues instead of TRV. So there you go, extra info and some effort to do a write up never hurts ;D
