Hi i need some help. my TRV was granted on 5th oct. this is the date which i mentioned to travel when i applied. Now due to some emergency situation in my family i have to postponed my visit to 27th Oct. Will this create any problem for me at port of entry and can i go with same itinerary of my visit like i have mentioned in my file that i have to go to jasper sky tram and jasper park, banff park etc or do i have to change anything because of winter coming in Canada. Any help will be appreciated. I have to book tickets as well.
