Is it possible to buy gold within an RRSP? Of course I can't just take cash out and buy it because I'll be taxed, but if I have cash in my RRSP account is there a way to use it to either buy physical gold, or buy gold in some way that can be redeemed for physical gold at some point (like when society collapses

)?
Or even just thoughts on investing in gold.. traditionally a historical high isn't usually the best time to "get in", but the ongoing weakness of the US and as a hedge against inflation is it appropriate even at this price?
