I agree with the simplicity -- we have two holdings. VDY for Canadian dividend paying stocks and VFV for the S & P 500 (listed on the TSX to reduce the conversion charges). 
The intent was to have about 50 50 but with the Trump presidency meaning bad news for Canada, coupled with a complete lack of confidence in Canadian leaders (except Wall), my Canadian holdings are now 1/7 or thereabouts. When our loonie falls below 70 cents -- and it will! -- I will increase the VDY component.
This strategy has done very well to date.
