Mischka - I called the CIC today to ask the same questions about the travel documents. The operator I spoke to suggested that I should call the consulate for the countries I have visited during the time period given (for me this is the UK, where I am from, the US and Mexico) and ask them about their procedures. I called the UK consulate in Ottawa and was told that my only option is to call the individual airports where I landed in the UK to ask if they can help. It looks as though there is some standard set up in the US for requesting that information at least but goodness knows who I am going to call in Mexico (I only went there on vacation!).
