There is no point of visiting the embassy. First of all they don't let non Canadian citizens enter the embassy unless they have an interview. Secondly, they will only answer general questions, and nothing about a specific case inquiry so as I said there is no point of wasting time and money. As for proofs, do send them updated emails, phone call logs, and proof of visit such as tickets, boarding passes, Passport stamps etc. that would definately help them make a positive decision during your initial review.
