My net worth is 3M with 1.6M invested in the stock market at the moment.
With XAW, VCN and ZAG it is impossible to reach certain % for emerging and international indexes.
Also, I have added preferred shares, REIT ETFs to my portfolio... and my TFSA is only TD bank at the moment.
I add 200K each year to my portfolio so my contributions far exceed the returns and it should stay the same til I retire.
In conclusion, you can and should tweak the CCP model so that it will suit your investment profile and your goal, especially once you have reached a certain amount of money.
