Hey. So I contacted IRCC multiple times after getting the COPR and visa in July, they responded with the standard email about March 18th, contacted again 3 times in Nov-Dec telling that my papers will expire in January and I’d like to come. But didn’t get any response. Then called the CBSA, some of the people I spoke to told it’s ok to come as long as we have valid papers, some of the officers told to wait. But we just bought the tickets and landed in Montreal, where we passed through all the immigration process, and then flew to Vancouver, just claimed the baggage, took the cab and came to the apartment we rented. We spent about 3hrs in Montreal on paperwork, so if you enter a city which is not your final destination and you have to travel to another citu straight away, make sure to have ~5hr waiting time
