You've posted this question a few times now. I know it's agonizing to make this decision.
If you buy an index fund, you are also owning, in essence, "bricks and mortar" of the businesses listed on the stock market. There is tangible value there as well - it's not just throwing your money on a roulette table, though maybe it can feel that way. If you're worried that you might panic sell in a downturn, then you need to think about a safer asset allocation, like 60% stock ETF and 40% bonds and pref shares. The bonds will drop less, and allow you to rebalance in the case of a market correction.
Also consider that RE values can also go down, as you are witnessing in Vancouver this past month. You are taking far more risk by having all assets in one basket, in the limited market of Vancouver real estate, vs. owing shares of thousands of companies around the world. If I were you, I would be looking to diversify as much as possible.
