I wouldn't be heavily invested in the Canadian market except for the dividend tax breaks. You say it isn't diversified - no shit, half the listed economy is banks + energy. And while I understand that financial companies allow business to happen, they are *pretty much* parasites - they output nothing useful themselves. Not saying they shouldn't exist or anything, but as an investable market, such a high proportion in one sector... no, in 5-6 companies? The TSX60 is horrible, a horrible index. The Composite isn't all that much better. Compare the market caps of anything past the first 50, to the bulk of the S&P 500...
10%, maybe. For a plain vanilla couch potato portfolio, 10% TSX Composite, 30% US, 40% ex-US and Canada, 20% bonds. Something like that. And the 10% unregistered; RRSP full of VTI, TFSA full of ZEA + XEF or whatever.
