house,
Vanguard ETF would be fine for you. Note normal Vanguard index funds available to Canadians is limited, but they have a great selection of ETFs. ETF would be fine since you're not making regular deposits and they have low MER. See

What I'm doing ATM is keeping my RRSP money in a bunch of TD index funds (e funds with MER of .3-.5%). I don't think you're allowed to use ishares or vanguard ETFs to fund an rrsp, so that is my reasoning.
