If you're already maxing your tax-advantaged accounts, plunk it all into an index fund (probably 70/30 stocks/bonds if you are risk-averse, but go as high as 100% stocks if you are 10+ years from FI). Not sure what specific products to recommend since I'm American.
Unless you'll be tripped up by your own psychology, do it all in a lump sum, NOT via dollar cost averaging. DCA limits your downside, but it also limits your upside. Over a sufficiently long period of time, lump sums always beat DCA.
Bonus: stocks (at least American ones) are on sale right now!
Canadian residential real estate is pretty pricey, though some blogs I have read suggested farm land is attractive, but that's way out of my knowledge zone. I'd stick with stocks and bonds myself.
