Anything fully Canadian is best taxable (ZCN.TO is what I use, hmm and some XCS.TO) due to the preferential tax malarkey. Then, something that holds stocks directly - not a wrapper for a US based ETF. Vanguard Canada are just releasing a global-ex-Canada ETF. Should be pretty funky, meaning a two ETF portfolio for stocks...
Canadian Couch Potato is a good site.
