If you live in canada, I would do these in this priority:
1.Drysuit - Water is cold. Being warm = more watertime = more fun
2. Advanced Open Water with: Navigation, Deep, Night, PPB and Nitrox specialties. -> This combo will give you access to the tools you need to be a confident (if you practice) diver in colder/darker/murkier waters and it will grant you access to the benefits and safety factors of nitrox (If you don't ride your NDL) and give you access to most warm water destinations. It will also ensure that you can use that drysuit into the darkness when winter comes. Winter is coming!
3. GUE - Fundamentals: When you have built some familiarity with the drysuit, book a Fundamentals class. It will fine tune your skills and make you an aware, buddy/team oriented diver with skills to keep you out of trouble. (There is no such thing as too early for fundamentals, but do your drysuit and AOW first because it gives you better outcome of fundamentals to have dived a drysuit first, and having deep and night keeps you diving through the year)
