You could try putting some of it in the 5 year HSBC "Great Rate GIC" (currently 3.7%) and some of it in the 2% Ally Savings Account. INGs rates are too low these days.
Also, if you have room to do so, put $10,000 of the cash in a Tax Free Savings Account version of the above two options since the TFSA limit for 2010 will be $10,000 per person.
