On our application form we stated our intended living areas as Vancouver, BC. However, when we finally are in a position to validate our landing visas we will probably do so in Nova Scotia because it's nearer for a quick holiday and we have some friends there we want to visit. Once we get back to the UK and sort our affairs we'll then start to look for jobs in Vancouver.
I asked this question on another forum, most people think it is irrelevant which city you put on the application form, you can complete your Record of Landing anywhere in Canada.
Generally I think the officials upon landing are only interested in your landing documents and proof of funds.
