Take your time developing your financial plan. Don't be in a rush. It does sound like you are trying to theoretically formulate a plan prior to acting upon it. Which is great.
It seems that you have alot of USD, which is surprising if you aren't really interested in holding any US equities.
To begin, I would keep it very simple, maybe 1 Reit ETF, and 2 Canadian ETF's if that is your plan. As mentioned use the Canadian Couch Potato portfolio and modify as needed.
