Canadian High Interest Savings Bank Accounts

I have about 37500 cash (all I have no house etc.)
I would like to buy a house sometime in the future so my money needs to be 100% secure. My banks interest rate (scotia) dropped to 1.25%.
Im am pretty much losing my money in this account what should I do?
I dont want to lock my money in for too long, a year at the max (preferably not at all).

I've looked at a few things like Government of Canada Bonds "not canada savings bonds" they seem interesting but I cant find much info on them ie how to buy, interest payed, etc.

If you have any idea's or info I'd appreciate it, thank you.

Ryan.
