We tried but since our old yahoo account has bee "recycled" by yahoo, it was impossible to get missing information. But CIC knows about our relationship for long time, because they have already issued me TRV to visit her family before we could start with building family together. And the problem with phone record is you can only go 6 month back, so we have kept record of last 2.5 years.
We never ordered notes for TRV refusal (honestly did not know before joining this forum that you can) the standardize letter we got was the purpose of the visit is not covered by this type of visa, and we are not sure if my spouse will leave Canada. We stated the purpose to start building the family together if TRV was issued (quite stupid, eh?)
