Best way to start investing given Canada's hot market?

[Francis Beattie]

Hi everyone! I'm at the beginning of my real estate investment journey in Ontario, Canada. I'm 27 years old and I'm finally making a high income that I'd like to use to invest, and start building my portfolio. I started reading books on rental property investing - but then realized that with the current state of the market in Ontario - it's pretty much impossible to buy anything at value, let alone under value, in order to build a cash-flow positive portfolio through renting. 

With all the different real-estate strategies out there, it appears to me that it's not a good time to start with rental properties. What advice would you have, or suggestions, around where to get started in terms of investment strategy given the crazy hot condition of the market?
