Yes, once you get your passport, you can simply move. When you arrive in Canada, if you're not given a record of entry as a Canadian citizen, ask for one.
You'll likely need it years from now when you apply for Old Age Security and they ask you to prove when you arrived. When I entered at a land border, I had already prepared a list of items I was entering with and their value (not the original cost, but the used value in Canadian dollars). Of course, I was coming across with a moving van filled with all the contents of my previous home. Anything on the list enters free of tax, but if you want to go back and get something to bring in later, and it's not on a list of things to follow, then you may be taxed on the new things. If I were you, I'd make a list (even if its small), just so you won't be held up when entering.
