My wife was with me on visit visa and later traveled back to my home country and again came back as landed immigrant.
1. Does the CBSA report even say when she left the country during the visit visa?
2. How to order CBSA report?
1. Unfortunately, CBSA record will not list exit records except maybe if you and wife went to US. (Canada and US now share exit records). If you still have flight itinerary, plane tickets, they can be used as evidence of when your wife left Canada.
