I haven't done any thorough research and my comment was not about the entire Canadian market, I can notice some correction in my local market anecdotally.

Real estate markets correct themselves and normally on a localized level.

It’s been my observation that a lot of today’s real estate investors have not been through a market correction, therefore they're still being aggressive because they haven’t faced any consequences of being too aggressive at the wrong time.

I try to read books on different kinds of realestate investing and house fliping and I do think that they are useful but the information never seems to have a correct fit.

The correct way to measure the overall performance of the investment would be through a Cumulative Return or Compounded Annual Growth Rate (CAGR).

But is WORTH it if you can do the correct things and really learn how this works.  

Correct, think of the IRA as a separate person.

And then I'd ride the wave and grow my business with it and stop when the music stopped. 

I think you did the correct thing here. 

But, in the event you really are persuaded that it is important to separate each asset, ensure that whoever is managing the books/monies on the LLCs are doing it 100% correctly as even a small mistake can allow would-be litigants to pierce the corporate veil and render all of it in vein anyway.
