I also think DM could come in a reasonable time, and yes, it likely will be in Montreal for the landing, as there is no office here in Quebec city. But honestly, the main thing for us was to get AIP; within the hour after receiving the letter, we were able to register my wife to RAMQ (Quebec health insurance) which we could not do before. We will also be able to register her for a French course supported by Quebec immigration, which we also could not do before getting AIP. Today was a huge step for us!
